The LM-845 Premium is a SET integrated amp that uses massive output transformers and a massive separate power supply. The driver tubes are 300B and output tubes are 845. I've upgraded the tubes to Western Electric. The authority, richness and soundstage this amp provides is outstanding. With the Aerial 20T V2 speakers it presents a huge soundstage that is silky smooth and powerful.
The Black Box is a Low Frequency Resonator Array that works in conjunction with the Atmospheres and FEQ X4 to solve bass node issues.
Thanks @aniwolfe!
I use Herbie's Iso-Cups under my Impact Monitors and have added some weight on the top of the monitors to stabilize/couple them to the Iso-Cups. It did make a very nice improvement. I haven't tried the Aurios or Rollerblocks. Please let us know how they work-out. With these speakers you can hear every change you make to your system!
