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.
I haven't touched my system for over a week now but did do some extended listening last night. The E-Cards and Total Contact are the real deal. Using just a modest (but well engineered) Yamaha receiver I'm getting really, really good sound. But, of course, I can't leave well enough alone so I've been looking at the Audio Magic line of products and have exchanged brief emails with the owner Jerry Ramsey. Here is a quote from his website which is VERY interesting:
"The theory about Pulsed Electron Alignment is based on how electrons spin. They spin either up or down in a phenomenon called spintronics. When there are billions of electrons all spinning their own way, it can create chaos in and around components. By aligning the electrons, you create a more efficient space and eliminate noise. This means that your listening experience is more realistic, with a more musical presentation featuring tighter, more dynamic bass, highs that are delicate and more natural and beautiful midranges."
