I'm not running an Everest, though I am running two Denali 6000S V2 units.
One handling the whole front end and the other handling the OTL mono block power amps and the individual DC power supplies to the voice-coil drivers of the horn loudspeakers. AND, my results have been simply stunning.
Micro and macro dynamics like nothing I have ever heard, textures on textures and layers on layers. The depth of stage has increased dramatically and the timbre of instruments and voices has become much more vivid and lifelike yet at the same time more effortless, truly incredible. I have utilized Shunyata Research cables, especially NR and XC mains cables before, having some very good improvements, but the (x)2 Denali have been a real game changer, one of the single biggest upgrades I've ever experienced. When the noise floor drops, the transparency really shines through.
I realize everyone's mileage may vary and audiophile hyperbole can get more than a bit ridiculous, but for me, my musical experience, and my kit, it has truly been remarkable. From my experience the amps sound better on it then off it.
DTCD is a very credible and critical aspect of what we do here.
