Just some feedback on these now that I have had them in my system for a few months. I ended up getting two of the "Eight Americans" for my A370 amps and a Eight+ for my Mini Torii tube amp. All three of these go into my MiniBuss. I am going to be using one of Dave's (P.I. Audio Group) PCs for the MiniBuss to the wall that he is building custom for me. I plan on getting a digital american for my DAC and I actually ended up selling both my phono preamp and my preamp.
My new phono pre is a battery powered Sutherland Ph3D, which doesn't require a PC.
I may try out a small isolation transformer on the DAC first. I've been looking at a Dale IT200.
re: the TWL PCs. All I can say is that I am impressed. They have more of everything. More dynamics, more bass, more finesse, more clarity and more blacker backgrounds. The improvement was not subtle.
Plus they have the benefit of being incredibly easy to route due to their heavy, but supple nature.
Pete, consider me a customer for life.
