Auditioned the Bowers and Wilkins CM10 s2 and sonus faber Venere S but actually preferred the Chameleon T in the end.  Although the preamp and amp are solid state, Cary voiced them to sound like they're tube-based, and the effect is astounding.  The Cary drives the 4-ohm Chameleons with 350 watts per channel effortlessly.  

I rolled tubes in and out of the Bellari VP130 phono stage and finally settled on the Mullard 12AX7, which I prefer for its clear, articulate sound, a significant upgrade from the stock tube in the unit.   Overall, however, the phono preamp is probably the next upgrade, in addition to speaker cables and interconnects (using AudioQuest Rocket 33 bi-wire and Diamondback RCAs and XLRs, respectively).  

Presently, my music interests reside solely in physical media (LP, SACD, CD) with no plan to venture into high-resolution downloads, but my preference may change in time.  I guess I have a thing for Marantz source components and deservedly so: they've consistently served as reliably high performers in my systems over the years.
