I had the non-tube version, was using Nordost Heimdall RCAs and an old PS Audio Mini Lab cable. This sounded pretty good to me. I later upgraded to the Frey (but had a difference source component), which was a major step up from the Heimdalls. What kinda "muted" the sound was a really heavy PS Audio Statement power cable (not SC version). This killed the mids and highs. A few folks have told me to avoid these kinda AC cables on my front end (ie, ferrite in the jacket).
All in, I really liked this set up. BTW, I'd also tried Cardas Quadlink (not bad, mids were really cool), and DH Labs (couldn't stand 'em, sounded really compressed).
