- Cube Audio Nenuphar (retired)
stock single driver full range TQWT floor standers - 92dB sensitivity / 30Hz to 18kHz frequency range / custom isolation stainless steel frame. An amazingly coherent speaker with nuance and resolution of mids but lacking critical balance of the entire frequency range.
- Tekton Design Moab (retired)
With beryllium tweeter. The classic ‘wall of sound’ speaker type, with cabinet colourations added to every track to the result of homogenised effect. Terrific depth of bass, to quite the lack of nuance in almost every other department.
- Townshend Audio Seismic Isolation Podiums
Size 3 / E cells for WVL Chicago
Size 2 / D cells for WFL Son
Enough has been said about these speaker isolation platforms - nothing floats speakers better to cleaning up slack in all frequencies.
- IsoAcoustic gaia isolation feet with customised speaker isolation platforms IsoAcoustics GAIA (retired)
Speaker isolation for the nenuphars had to be customised because the speaker employs passive downward porting for its bass frequencies, with a back tilt for greater bass impact to the front of the speaker - with clear gaps of 40 to 41mm at the front and 5 to 6mm at the rear of the speaker base to the floor, it was not possible to use any isolation products just off-the-shelf: regular OEM feet would have just raised the speakers a level height off the floor, ignoring the designed back tilt of the speaker for wave throw and something like the Townshend podiums would have put a damped platform right where a solid floor surface was planned to be for the downward exiting low frequency waves. The customised platforms are made of 6mm thick stainless steel and plate, cut and welded to design in order to be lift each speaker to it’s designed angled height off the floor surface, in tandem with three Gaia 1’s for each speaker, calibrated and matched by weight of speaker to Isoacoustic’s specifications. The jump in sound quality, of natural and dynamic timbre throughout, nuance of bass, and fleshy rather than ‘wet’ realism, was unexpected and gladly welcomed.
- Lessloss C-Marc loudspeaker firewall
These little skin filters sit between loudspeaker cable and speaker binding posts to help eliminate high frequency noise pollution from the signal. Counterintuitive as it may seem, having added points of contact along the final part of the signal chain, these small tubes of tech create a subtle but clear lowering of the noise floor, lifting the music to greater clarity and air.
- Siltech Cables Royal triple crown speaker cable
These cables brought a significant change to the realism of sound in my system - a small bottleneck cleared to allow more upstream to come through. I have not heard such change to sound balance or realism in any other speaker cable regardless of cost, than with the siltech triple crown cables. Other cables tested include range topping cables from Audioquest, Argento, and Inakustik, the Kharma Enigma Veyron, and Tellurium Q Statements. The Nordost Odin Gold came close, but was let down by a subtle exaggeration to the high frequencies, besides being unmanageably stiff along its flat axis and a handful to route. The only other speaker cable I would consider, siltech aside, would be the Inakustik LS-4004 pure silver cable, the best performance for money I know of.
Custom cable lifters have been made from plastic subsoil drainage piping and zip ties.
- Tellurium Q silver diamond speaker cables (retired)
stock locking banana connectors with custom plastic cable lifters made from flexible subsoil drainage piping and zip-ties.
Good all round cable, but in final estimate, not worth the cost over the super affordable duelund v2 speaker cable.
- Silversmith Audio Fidelium speaker cables (retired)
These cables were originally used between the AS125 211 amp and the Tekton Moabs, followed by the Cube Nenuphars and then the WVL Son speakers, in all cases to a loss of balance in the low frequencies. The cables are decent value for the money, but lack authority, midrange flesh, and nuance of bass.
- Duelund Coherent Audio V2 speaker cables (retired)
Where the silversmith fideliums lack control over bass frequencies, the duelunds fail to bring life to the highest frequencies.
- Elac 4Pi omni-directional tweeter
The little elac tweeter was chosen on account of its 360 degree ribbon driver. Many super-tweeters feature considerably more focused dispersion, with only the Arya Audio Airblade topping out at 180 degrees, to effect that they compete with the tweeter/s of the main speaker instead of performing the role of subtle augmentation, being the primary idea behind the typology - in many cases, the Airblade itself functions best when turned away from the listening position for its benefits to be best heard as reflections off the front wall.
The strength of the high frequency soundwave emitted over its narrow dispersion band is both the blessing and curse of the typical supertweeter.
Not so with the Elac 4Pi - with its fully omni-directional wave dispersing the intensity of the signal over 360 degrees, it recreates the propagation of soundwaves the way they would be heard in a venue of live music. The elac delivers the most nuanced rendering to the space and air of each recording in seamless congruity with the how the WVL Chicago dipole speakers function. The strength of timbre and decay from drum, violin, voice, piano strike or guitar, and the powerful way the resonant air of each recording venue distinguishes every track from another, creates a deeply palpable realism in the remarkable effect it has on the soundfield.
The tweeter sits on a custom frame integrated with the main speaker base, with lateral support from the audio frame of the WVL speaker. The tweeter frame has been fabricated from brass for the relative dampness of the material in relation to the required strength, and has been designed to be retrofitted or removed independently of the main speaker itself. The assembly for the tweeter frame is incremental, beginning with the level adjustable feet screw-bolted to the existing threaded holes originally intended for the proprietary feet supplied with the main speaker. The main speaker together with tweeter support frame thus rest on the same speaker base, with the entire assembly seated on the Townsend isolation podiums.
- Inakustik LS1205 silver air speaker jumper cables
The Inakustik line of silver cables have consistently been found to be the best value for performance through listening comparison with many others. In this particular case, by a wide margin. Connecting the elac tweeters to their respective channels via the main speaker cable junctions to the lessloss speaker firewalls, the LS1205 cables were customised with black sleeving instead of the standard white throughout, rendering them indistinguishable from the air copper cables. Sound quality from this addition is extraordinary - for inexplicable reasons, the realism of decay with piano strikes, strong instruments, the resonant air in whatever venue the track was recorded in, everything comes to life with the cables put to the omni-directional tweeters.
- Lavricables Master line v2 silver speaker jumper cables (retired)
These cables replaced the omega mikro flat cables to considerably greater realism in spatial texture and detail - its sound quality to cost value is extremely high.
- Omega Mikro Ebony speaker jumper cables (retired)
Connecting between speaker binding posts and Elac 4Pi omni-directional tweeter, these were the first cables used for the function. Far from the best value for their performance in all frequencies, even with almost unusable fragility and durability aside.
- Rythmik Audio F12SE subwoofers
Four F12SE servo-assisted subwoofers in an asymmetrically configured distributed bass array. Fed from pure silver power cords from lavricables and supra rondsubwoofer signal cables split-wired from the high level signal path of the speaker binding posts. The subwoofers sit on basic douk audio spring isolation feet for the high amplitude vibrations experienced by low frequency excursions inherent in subwoofer drivers, which neither revopods, isoacoustic apertas, or other subwoofer specific solutions were able to tame.
- Supra Cables Rondo speaker cables and CombiCon connectors

- darTZeel NHB-108 MKII amplifier
With CMS 2m isolation, this amp delivers a midrange and upper frequencies with a realism I’ve not heard in any other amplifier. While its performance with bass frequencies may not be the very best, it still holds its place as one of the most balanced amplifiers available at any price.
- Kinki Studio EX-M7 power stereo amplifier - dormant
This amp may not be in current use in the system, but of all the tube and solid state amps tested and demoed, it has so exemplified the powerful equation between cost and value, that it has stayed while others were returned. In relation to everything the best amplifiers do, which is to get out of the way of the signal in merely amplifying it, this little black box may lack refinement in the mid and higher frequencies as compared with the Dartzeel NBH-108 model2, but I almost all other aspects, walks among the best. Armed with its internal fuse replaced with a solid rod of graphene, equivalent in sense, or perhaps even bettering the magnetic circuit breaker the Dartzeel amplifier employs, the kinki amp takes sound quality up very close to levels commonly the domain of Pilium and the Swiss amp army.

The amplifier that began and tuned the journey of my second system was also ultimately what held it back, it’s western electric based hand-wound transformer insufficiently coiled to deliver the highest frequencies for timbre and air.
- Arya acoustics Revopod isolation
six in total for the base mass damper which the amplifier sits on - together with the independently sprung plinth beneath in vertical isolation from the rack, and the CMS feet above it in horizontal isolation from electrical vibrations from the amplifier, the mass damper provides a third intermediary isolation layer to complete the set up.
Also employed under ancillary components - four each to the custom steel shelf for QNAP server lifted over the isolation router and switch, external power supply for preamp, and Melco CD ripper.
- Arctand prototype RCA cables
These rca cables handily outclassed all the others before it in relation to dynamics, air, and realism of timbre, sitting between DAC and preamp, and preamp to amp. Interestingly and oddly so, they also outperformed the specially designed impedance-matched 50ohm zeel BNC interconnects between pre and amp. Compared with this cable, the siltech triple crown XLR between DAC and pre sounded hard, almost digital-like, and a touch lifeless.

In a sense, the dartzeel pre was the component which began a divergence in the direction of the system build, and formally created the second part of the journey.
Up till then I had always believed valve preamplification and amplification was the best way forward as the means to tame the glare of digital streaming. Through a startling home demo followed immediately by lots of reading about preamplification, i began to realise that the taming of digital glare, or what most refer to as the creation of warmth, was a complete misuse of analog preamplification, if indeed capturing every nuance of realism in the signal is the intention. While its original functional as a switching hub for multiple sources may appear redundant in a purely digital system, the other most vital function of the preamplifier still stands - this being its responsibility of executing the very first amplification step of bringing the infinitesimal millivolt recorded signal up to that of a line level signal which can be easily taken over by a power amplifier - in any transaction of life, be it taking off or landing in a plane, the act of purchasing a house, birthing a newborn, or bringing an electrical pulse to accurate sound waves from a speaker driver, it is inevitably always about the flow and precision of the handover. This was what the preamplifier was about.
Moving on, and with a few more alternative home demos after the first shock of hearing what a good preamplifier could do, I also began to hear and understand that for this vital first stage, tube preamplification simply introduced too much distortion for that first signal gain to sustain accurately - in the same way odd high order harmonics creates the illusion of loudness, what i perceived to be a widening or deepening of the soundfield with the tube preamplifiers I demoed was actually bloating, an odd ambiguous expansion across all recordings, with the nuance and detail in that soundfield commonly lost. It was only in the most exceptional solid state preamplifiers that I heard the soundfield of each recording for what it was as recorded, and the soundfield of each track would be exactingly wide, deep, or both if recorded so, or narrow in bits or whole, skewed or asymmetrically focussed if recorded otherwise; the soundfield changed according to the specific context each track was recorded in.
That pinpointing of every and indeed, any player in the space of the soundfield, together with the tone and timbre of each instrument or voice coloured by their place and location in that soundfield was what ultimately drew me back to the dartZeel pre, something I have since found only the most refined solid state preamplifiers do.
- Telos Audio Design BNC/XLR terminator caps
These terminator caps were acquired for the preamp with its multiple unused input and output ports - points susceptible to the entry of EMI/RFI disturbance.
Their effectiveness is small, but still detectable without an A/B, contributing to a finer grain of texture and air in the music. This, with 12 BNC and two XLR ports plugged.

This preamplifier, cost for value, was easily one of the best components in the system, doing everything preamplification is supposed to do. Everything else levelled in my listening space, it came close to equalling the Pilium Ares preamplifier at close to five times its cost, with A/B listening required before the strengths of the Pilium could be identified over the LM129.

current reference DAC with CMS 2m isolation.
Compared in the same listening space with a large variety of other DACs of multiple price points, the wadax atlantis possesses a degree of realism unparalleled by almost all others. It is more realistic than the stock MSB select II DAC in every aspect of timbre, soundfield, mid range, nuance and control of bass, bettered only in the highest frequencies and finest details. The select II exhibits slightly sharper detail when running on XDMS, but even so, is unable to keep up with the depth of realism of timbre and soundfield with the wadax on roon, which it’s architecture was built around and upon as a foundation.

- Taiko Audio Olympus / iO server
While power is everything in high fidelity audio, in the highly sensitive realm of the digital source, too much power corrupts, and in the very silent environments of an ultra low power server or streamer, high resolution files above 192khz will not sound as good as those at the basic 44.1khz sample rate - the reason being the greater power needs required to process higher resolution files produces such huge quantities of electronic noise, that very noise overwhelms the benefits gained with that file of higher resolution. Few servers underline this issue better than the Taiko Olympus, the gains of which surpass the previous Extreme in the system by a substantial margin of sound realism. It draws home the point of signal corruption through digital noise in source components being one of the primary contributing factor to the degradation of every aspect of the frequency depth and nuance, dynamics, timbre and realism of the soundfield.
Together with the taiko router and switch, the Olympus and iO server with its XDMI interface isolates and reduces digital noise to such a degree, its results equal, if not exceeds the delta more commonly found in the cleanest power and basic full system grounding solutions.

- TP-Link TL-WR902AC AC750 wireless travel router
As with all source components, power in the digital realm corrupts the timing and nuance of the digital signal. Few other examples demonstrates this better than the little TP-link WR902ac, a tiny pocket wireless router with just one single function in client mode: to pick up the streamed signal from the mother router over a WiFi bridge.
The discovery of its use as an ultra low power consumption WiFi bridge over its single function in client mode was made by the German audio hobbyist, Eric Giese of ethernet-sound.com, and then circulated globally through audio forums.
Basically, the common mode noise created by upstream components right up to and including the mother home router, becomes isolated from the signal chain downstream with the use of the travel router as a WiFi bridge, it’s super low power consumption aiding in the further reduction of noise to the signal.
Its effect is not just palpable, but the equivalent or more, of the addition of a very high end switch or major component change. Further investigation involving Ethernet choke cables as configured by Eric await implementation.

- Plixir Statement BDC 12V linear power supply
Feeding the modem and asus router, the soundfield produced by this power supply to the basic modem and ASUs router is deep and powerfully nuanced - its definition brings timbre of realism to instruments and voices created by the character of each venue the recording may have been done in further differentiating one track from the next. From having demoed other power supplies working off super capacitors in the system, it is apparent super caps degrade soundfield quality when used on source related equipment of modems and routers. The plixir statement BDC sits shoulder to shoulder with the Sean Jacobs DC4.
Twelve groundaray bullets plugged into the unused terminals/ports of various pieces of equipment - three into LAN ports of modem and two routers; two into USB ports of server; three into BNC and RCA ports of DAC; and four into RCA and XLR ports of preamp. The groundarays make the greatest difference to sound quality plugged into source equipment, removing haze and all the edge that characterise noise. Are passive grounding solutions such as the CAD grounding boxes and these groundarays better than active solutions with their connections to power outlets? Time will tell.
- Sablon Audio Ethernet cable

- Russ Andrews Technical weave Ethernet ground cable
The ground cables which connect modem and primary router to the grounding post of their plixir statement BDC power supply, are the same ones that begin the journey of the daisy-chained ground line which follows the digital signal path. These technical weave grounding cables perform the task of cleaning the fine EMI introduced by the source components of modem and router, in creating a low noise environment for better signal transmission.
- Lavricables Custom 10x26awg pure silver component grounding cables and 20x26awg pure silver speaker grounding cables
These black silk sleeved grounding cables were the final step in the system build, replacing the cheap lamp cord which alone had already brought such dynamics, nuance and depth to the music, the custom silver cables were an experiment of sorts, to see if greater sound realism could be achieved.
The cables were made in two sizes, correlating to component and speaker grounding networks. Totalling approximately 15awg in stranded individually Teflon insulated woven cables for the components, and 12awg for the speakers, both in pure silver.
Component grounding follows a tested star-ground configuration to the grounding router, while speaker grounding was routed in two lines per channel; one daisy chaining speaker drivers back to the same grounding router shared by the components, and another grounding the negative speaker post to a dedicated CAD GC3.1 box, one to each channel.
The grounding lines were laid incrementally, beginning with components, followed by the negative posts of the speakers, and finally with the speaker drivers. Each step of the way brought realism uplift far beyond expection - the profound effect with all three ground lines in equalled the combined improvement of every large and little change to each component, cable and vibration isolation device in the system.
- Russ Andrews super router SE with premium technical weave ground cable
This simple grounding router is at the heart of the system; the single place where every component finds its way to by means of a grounding cable network. Pure silver 12 and 15 gauge woven cables connects each component separately to the WBT binding posts of the router: LPS for modem and ASUs router; dc distributor; isolation router and switch; server, DAC and their battery supplies; negative inputs for each channel of the amp and preamp; and the ground post on the primary power distributor all find their way to one or another of the binding posts on the super router. Two more posts take ground cables from the connected steel field coil drivers of the speaker of each channel. A premium technical weave ground cable with total cross-sectional area of 7gauge connects the router to a solid copper grounding rod in the garden. Together with the external ground copper rod, the connecting premium technical weave ground cable, super router and entire network of ground cables taken as a single structure, no other component addition or development in the build has had greater impact of refinement to the system in entirety.
- Tokai Concrete Inspection chamber, brass clamp with copper fastening bolt and 19mm diameter 2500mm solid copper grounding rod encased in marconite.
With the rod buried in the garden vertically in a six inch cylinder of marconite for maintenance free grounding, the ultra conductive compound has brought sound realism to unexpected levels - high piano notes and guitar plucks are crisper the way it actually sounds, soundfield depth has once again increased, voices are heard from the throat in living realism, drum beats have become fully fleshed and heard from the skin of the drum, guitar strumming comes from the sounding hole of the instrument, choral voices are distinct and separate (never mind the absolute clarity and distinctness of duets, and the unique character and detail of recorded room decay, resonance, instrument and vocalist separation has developed distinct outline and absolute nuance. Comprehensive system grounding has been found to be about the most impactful part of the system build.
While the previous daisy-chained ground path to the single GC3.1 outperformed star-arrays for signal and chassis grounds into separate GC3.1s, the same uplift found by daisy-chaining did not apply with the external ground rod in place, with a single star-ground of component chassis to super router connected to externally embedded solid copper ground rod delivering the closest approximation to realism yet, and profoundly so. Each component is separately grounded to the super router, except for modem and ASUs router which are Y-grounded to the binding post of their plixir LPS, and from there connected onward to the super router. All components with external power/battery supplies have those supplies first connected to their associated component. The Furutech Powervault distributor is grounded directly to the router, with each channel of the dual-mono pre and power amplifiers Y-connected to ground inputs of the router. A final premium technical weave ground cable of combined cross-sectional area of about 10mm2 connects the super router to the marconite encased 2.7m solid copper grounding rod just outside the listening room in the garden.
The uplift to sound realism with this single star-ground compared to the previous daisy-chained path to a single CAD ground box, as well as the original twin star-ground configuration to separate signal and chassis grounds with the twin CAD GC3.1s is profound and far beyond any need to A/B the result.
Also chassis grounded are the steel field coil drivers of the speakers, left and right channels silver wire daisy-chained to the super router. The mere act of grounding the chassis of the field coil drivers was almost equal to the effect of grounding the entire system.
Having been tested with a variety of different configurations of grounding routes and types of cables/wires for the most realistic outcome in relation to soundfield/timbre, the entire grounding network has now found its final implementation in the pure silver insulated cables hand woven by Konstantin of Lavricables cables. Stranded and solid high cross sectional copper, woven pure solid core silver, silver plated copper, and woven copper ground cables, all underwent test listening prior to the final decision which presented the greatest refinement to sound realism.
- Computer Audio Design GC3.1
Previously used in combination to route signal and earth ground cables separately to two dedicated GC3.1 grounding boxes, each box in star ground configuration. Over time and experimentation, it was discovered that better sound realism could be achieved, oddly enough, by following the signal path in a daisy-chained chassis-grounded combination of CAD and Bibacord ground wires connected to a single CAD GC3.1 following the sole signal path of the digital source.
With a nine foot long solid copper grounding rod now in place which all component chassis are now star-grounded to for far greater realism, the GC3.1s have been repurposed for the sole routing of signal grounds from the negative terminals of speaker posts, one ground cable each to dedicated GC3.1s for left and right channels.
- Swiss Digital fuse box 240V - 10A / 4A / 3.15A / 2A / 0.5A
The little device that will fundamentally change how electrical protection systems for audiophile equipment are designed, has replaced the traditional fuses in my server, DAC, external battery supply for preamp, linear power supplies for modem and primary router, and DC distributor to isolation router and switch. Another serves the power supply for the field coil drivers of the WVL speakers, with four more for each subwoofer in the distributed bass array. The swiss digital fuse box is the single greatest value-for-cost addition to my system.
Prior to the final configuration of fuse boxes in my system, they were tested on all downstream equipment which employed fuses that could be replaced. The effect on these yielded better sound quality than any power cord change, but not as dramatic an improvement as with their effect on source equipment, meaning from the DAC and everything else before that, including linear power supplies for switches, routers and modem. The effect on the modem and mother router was almost equal to that of the server.
Above and beyond power supply being the most vital part of any sound system, the swiss digital fuse box has shown it is specifically on power supply to source equipment that creates the greatest difference to the dynamics, timbre, and realism of sound depth, more than any other part of the signal chain in a digital audio system, with just one significant exception. The preamplifier in my system is the Dartzeel nhb18ns, which employs an external battery power supply. This being the case, I did not think the replacement of its fuse with a sluggo would be of any consequence whatsoever. I was wrong. From initial belief that source equipment benefitted most from the digital fuse box, I was stunned to hear the tremendous effect on the sound depth and timbre of realism brought by the graphene sluggo in the mere battery power supply of the preamp. The fuse within the pre has not been replaced with a digital fuse box and sluggo because it’s battery supply is hardwired to the pre, and the fuse within will require opening up the pre to replace - leading to more difficulty than I am willing to currently endure.
The set up currently has graphene sluggos in the server and i/o, DAC, the external battery power supply for the preamp, all linear power supplies for the modem, routers and switch, and rhodium coated tellurium sluggos for just the subwoofers.
- Revelation Audio Labs Modified Furutech FI-28 rhodium and FI-50NCF 3-pin NEMA to C13 iec adaptors
These adaptors were customised by Brad Vojtech using solid cryogenically treated silver connections within. The adaptors were commissioned as a less compromising and more compact alternative to the pigtails connecting digital fuseboxes to components. Lift to sound realism is subtle, but a clear step up.
- Zayin Suprareg Lite linear power supply
This little power supply currently feeds just the taiko DC distributor, which powers the taiko isolating router and switch, to effect of greater detail to the soundfield and a lighter more realistic character very different from the thicker sound of the farad super3 power supply.
- Farad Super 3 linear power supply (retired)
With fuses replaced with graphene coated sluggos, fthese previously fed all source equipment of modem, routers, and switch. Over time and evident listening, it was found that the supercapacitors in the power supply presented a weighty sense to the sound and a more opaque view to the soundfield, Having been comprehensively supplanted by the plixir statement BDC, a single farad super three now feeds the QNAP NAS via a 2.5mm farad level 2 silver DC cable, sound quality on the main signal path being generally unaffected by power feed to the NAS.

Comprehensive listening tests place this unheralded cable in the realm of range topping power cables from Ansus, Furutech, Argento, Nordost, and Siltech, with shortfall, if any, only in the nuance of bass frequencies, discernible only with A/B/A testing.
- Furutech Project v1 cables (retired)
Good as they were, the project v1 power cables have been entirely replaced by the Inakustik 4005 power loom which perform at a significantly higher level of resolution to the soundfield.
- Inakustik AC-4004 air reference power cable (retired)
Formerly feeding amplifier and dc distributor for the taiko switch and router.
- Lavricables Grand power cable
For power connection to all subwoofers.
- Ansuz Acoustics C2 power cable
Serving as a pigtail between the Swiss digital fusebox and the WVL speaker power supply; and as power feed for the linear power supply to the QNAP nas.
- Shunyata Research Alpha NR V2 power cable (retired)
For connection between Furutech wall outlet and preamp external battery power supply.
- Synergistic Research Powercell SX (retired)
With all components previously connected except for the power amplifier high voltage input and the preamplifier. This power distributor was disappointing.
- Synergistic Research SRX power cable (retired)
Connecting the powercell to the Furutech shielded wall outlet.
- Furutech power vault - shielded/unfiltered distributor
The power vault serves the power needs of server, DAC, preamplifier and amp. It sits vertically in its wall mounted custom isolation holster bracket, with two large Isonode hemispheres for the base and four small hemispheres to isolate the upper body within its holster. A brass clamp beneath secures the incoming power connector to the vault. The vault with the SA-TT7 which powers the source components of modem, router and DC distributor, forms the foundations of power delivery for the entire system.
- Sound Application SA-TT7 240v filtered power distributor
The SA-TT7 feeds the entire source chain from modem, to router to DC distributor, with the distributor itself powering the taiko router and switch. It was ultimately felt that whereas supply to the power hungry components had to be well-shielded but completely unfiltered for the least constrained flow, that the more power sensitive source equipment would benefit from the nuanced filtering afforded by the SA-TT7. To this end, the filtered distributor profoundly elevates the soundfield to fresh depth and nuance.
- Furutech #1 and #2 e-TP609 NCF unfiltered AC Power Distributor
with internally rewired CB10 cabling enhanced with NPS1260 contact fluid, installed as a six plug wall power banks with Furutech NCF booster bracing for all outlets; and hardwired to the house mains distribution panel with Furutech CB10 10 gauge wiring to a 50amp circuit breaker.
- Wellfloat Delta isolation base - 20mm height
Four isolation bases for each leg of the tower audio rack. The one kiloton capacity of the deltas have replaced four Townshend seismic isolation corners that were barely holding up to the extreme load of the rack.
