Hi Guys,
Just saw the recent thread and thought I would throw in my two cents (about ugrading to higher power amps). I have a TA-1000 Mk 2 preamp, TA-3000 Mk 2 phono amp and used to have the TPA-30's. Of course, they all sounded great together, but I needed more power when I changed speakers (bought Avalon Acoustic Radians). As a result, I sold the TPA-30's and bought Canary Audio CA-160 monoblocks (140 watts ultralinear and 100 watts triode). I've had them about 9 months and couldn't be happier with the amps.
Again, speaker synergy is key with any amp, but the Canary's have been matched with 3 different speakers in my system (Avalon Radians, SAP Audio Quartettes and Von Schweikert VR-6's) and I have been pleased with the results with all of them.
I love the Thor gear though, haven't heard a preamp yet, that I would trade it for.
Best regards,
Dave
