Teajay,
The MZ2 is still amazing me as an integrated amp. Purity, clarity, blackest of backgrounds, amazing tone, very dynamic, amazing bass........what more could one want? Well.....maybe a tad bit more texture and air.....the meat on the bones you refer to. I'm currently using NOS 40's RCA 12SN7's with NOS 50's RCA 12AT7's. I have a pair each of NOS TungSol round plate and KenRad 12SN7's with a pair of NOS 40's Mullard 12AT7's on order. Any idea which of these might provide some of that meat on the bones? I'm sure the Mullards will add some of their famous warm tone. Any other tube suggestions would be appreciated. I figure I'll play around with tube rolling in the MZ2 until/if I get an amp. The Triode Lab 2A3 FFX seems like a winner to me, especially since it fits into my budget.
Thanks
