+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.
