The best tube poweramp. . What do you think about ?

+1. There are plenty of suggestions, and some are better than others. I would not make any change without a home demo showing a clear improvement

ebmVAC stick with a winner.

I've had Cary and VAC for 20 years.  Never saw  any reason to change.  Sound, soundstage, and every other factor has me getting lost in the music every night, without exception.  If I had to upgrade my VAC at this point I'd probably look for a used 300i!  If you need to upgrade, stick with VAC.  They are brilliant, and the best customer service I've ever encountered.

... sorry, meant to reference the phi 300.1that you already have :-)

Yes, articdeath, but Carver 275 + a pair of Carver 350’s in biamp’ed setup is even better.  I’ve never heard the Silver Sevens.

McIntosh!
