Carver Crimson 275 tube power amp

Naim 272/XPS preamp/streamer

pair of REL T5i subwoofers

Bluejean cables

I upgraded my main preamp from 272/xps to 252/supercap and now using 272 on my office system. The preamp replaced Mcintosh D150 digital preamp and it costs more than everything else combined but improvement was dramatic.
