A motley collection of components and cables that sounds pretty good. 99% streaming via Tidal. The SQ is full-bodied, dynamic and immersive.
I'm from the school that everything matters. Constant tweaking over the years. I didn't know what my system's potential was until the electrical power was cleaned up. As it's become optimized, the music is magical.
I prefer large monitors and powered subs over full-range floorstanders. This allows better fine-tuning of the bass to the room nodes.
Transparent Audio believes that the power to each component should be isolated to prevent cross-contamination - especially with digital gear. Digital gear regurgitates noise back into the system circuitry which affects the SQ of the other components. So, each primary component in my rig (analog & digital) has its own dedicated Transparent Audio PIMM (Power Isolator MM series). Each PIMM is plugged into balanced power. In other words, the power to all the components is both conditioned and balanced - including the modem & router. The power to the SS amp is not balanced - only conditioned (non-current limiting). All LPS's - no wall warts. After-market footers under everything.
After installing the PIMM's, it was extremely easy to hear how a power cord influenced the SQ. It's taken years of auditioning many different brands & models of power cords to find a synergy that works for my ears - matching specific pc's to specific components. The analog & digital interconnects are Synergistic Research Atmosphere Level 4 and speaker cables are WyWires Gold Series.
My latest tweak was to deal with the EMI that was emitting from my large transformer-based components. The SS amp & balanced power conditioner have been repositioned - from below and behind the rack - to one on either side. This places them further away from the cabling and source components. The EMI was definitely affecting the SQ. Better everything - timbre, sound stage, imaging.
Older Wilson speakers with the Focal 1" titanium coated tweeter have a bad reputation for harsh highs. Not in my rig.
Getting a decent equipment rack is on the To Do list.
