AVM SA 6.3 Stereo Amplifier - Any thoughts?

Hello all..Looking for your valuable opinions. I have an aging Gamut D200 amplifier and I am looking for a replacement. As Gamut no longer manufactures electronics I am looking at the AVM SA 6.3 stereo power amplifier vs an offshoot of Gamut, the Gato Pwr222 Monoblocks. I’m looking for opinions on either but mostly the AVM brand, as Gato shares near identical topology with Gamut. Unfortunately no AVM dealers anywhere close. Thanks to all! 

Figured I would chime in quickly to say how elated I am with my SA 6.3. It is far and away the best amp I’ve had in my room, and possesses tube-like qualities, musicality and smoothness in spades. Together with a PA 5.2 running NOS tubes, I am getting incredible performance. I plan to upgrade to the PA 8.3 at some point but would really like to hear it first.  I have mention that the factory 803T tubes that come with the PA 5.2 were.. Not. Good. lol.. max performance is significantly higher with NOS tubes in my experience. 

Frankly, I am surprised that there is not more info circulating about these products. They ought to send more out for review, I think. 

Glad all are enjoying the SA 6.3. It’s a great amplifier!  I actually went on to purchase a Coda 16.0 which shares many excellent sonic qualities with the AVM line. Enjoy!
