Valve Amplifier suited for my system

I have heard Living Voice IBR-X driven by Shindo and it sounded GREAT. I am sure your other choices are just as good. Try to keep it above your 15wpc mark as suggested earlier.

Another amp you might want to consider is Consonance-Opera Cyber 211
($5500 new) or 300B PSEs' 15 watts . It was compered to famous Audio Note in Enjoy the music review.

To sum it up. Tubes will work great with your speakers.

Another vote for Vac Phi 300.1 amp. A "statement" piece.

Yet another for the Phi 300.1, I just ordered my second one and am going to run them as monoblock's.... :-)

How about SET amps from Audionote UK

The KR Audio amplifiers aren't lush sounding. They aren't hard or brash either. I haven't heard the other amplifiers you have named ,but I can tell you the KR amps are EXTREMELY transparent. The bass from these units must be heard to be believed!They have been called the Krell of SETS..I agree 100%.

If you're looking for backgrounds as black as the abyss. This is the quietest amplifier I have ever experienced. I mean nothing from the speakers. Even with your ear an inch from the driver.

I would be careful with what preamp you match with one of these. Because if the preamp is noisy..your going to hear it.

These have to be one of the best kept secrets in audio. For the used prices they are a steal!

Your wallet may thank you even if your back doesn't.
