David,
If you go the Decware route I have a like new Torii MKIV I'd make you a good deal on but to be honest, as far as I'm concerned, the MZ2 sounds MUCH better.
The LIO looks very intriguing. Vinnie Rossi has some interesting products. I ordered his mini Pure DC-4EVR power supply for my MZ2 and am looking forward to hearing what difference it makes. As far as other tube amps I can't help as I'm sold on the Aric Audio SET KT 120 and will be ordering it Friday. I'll be getting the Concert Fidelity 040-BD DAC from Audio Archon in the next few days also. Once I get the CEC TL3.0 cd transport, I'll have the same system as teajay.....or at least the DI version of it. Imitation is the sincerest form of flattery.
