Best amp for Sonus Faber

+1 @lalitk I acquired an Accuphase A-80 amplifier a few months ago. This machines makes the most beautiful music I have ever heard in my system. Over the years, I have gone back and forth between solid state and valves. Each time, I would miss the virtues of each design. When I went solid state I loved the bass control and authority, but I would start missing the beautiful midrange, the air, and dimensionality of tubes. So I would go back to tubes.

With the Accuphase, it is the first time in my journey that I don't miss tubes. I don't know what Accuphase has done recently, but this is about as perfect as it gets for me. The sound is rich, somewhat midrange centric, full of harmonics and tonal density that only tubes can otherwise provide. Yet, thanks to it's high damping factor, this beast produces the most satisfying bass I've ever heard in a solid state amp.

"MacIntosh produces a very heavy midrange and bass but is light on the details..." 

For what it's worth...

This was my experience as well.

Earlier this week I listened to the SF Cremonese, powered by McIntosh mono-blocks (600 Watt, each). In fact the entire rack was McIntosh, including the Mc Turntable (Clearaudio).

For $55K speakers, the sound was VERY disappointing.  After a minute or two I realized that I was hearing a very clear representation of the McIntosh gear.  Heavy mid-range, anemic in the highs.  I was expecting much better...

Always demo, and good luck.

Are you considering tubes? McIntosh or cj or VAC.  Although I guess solid state would be OK for Sonus but I'm not a big fan of solid state except for the base drivers. Solid state probably shred mid range and tweeters sound on the Sonos. It is so much better with the tube amplifier.  

“Mostly from people who do not own a Sonus speaker.”

I don’t think any of us can really know what everyone here has owned or currently owns, so saying it’s “mostly from people who don’t own Sonus” feels a bit presumptuous. Different experiences—whether from current ownership, past ownership, or extended listening—can all add value to the discussion. That’s the beauty of a forum like this: a range of perspectives helps us see things from angles we might otherwise miss.

@lalitak that is why I said mostly.

I try to add my experience as we are able to listen to so much equipment and can offer very good experience to help others.

Our repair and listening facility has in general over 20 amps, preamps, DACs, phono stages in each month to compare with various speakers.  Actually, we are always learning new things and can share those experiences.

I have always welcomed anyone to come to visit us in New Jersey to hear what we hear and learn as we do.

Happy Listening.
