I've a somewhat similar system in my office and I'd assume it is the Rotel. I bet a tube amp would be spiffy.
What's in your Wadia iTransport system?
I am having a difficult time working out the "hard edge" in my current system: iPod 160gb Classic (lossless) > Wadia iTranport > Cambridge DacMagic > Rotel RSP-976 > Rotel RP-985 MKII > Paradigm Studio 20 v3. The Rotel components and speakers were purchased used on AudioGon, the remaining purchased new. Total investment ~ $2,500. I would appreciate hearing about your iTransport system and investment. Also any suggestions on next-step cost effective improvements on my system. Thanks very much.
