Pass....Accuphase....or......

+1 @bjesien as an owner of the Parsifal Encore I totally agree with your recommendations for something with both power and a bit of bite.

I have the XA 25.  Digital source is the Esoteric K-01XS, pre is Benchmark LA4, speakers Rockport Atria II (which, thankfully, I bought before the 50% price increase!).

Yes, it IS really good.  My room is a bit larger than yours, 25x45, and the XA 25 can fill the room - I listen to "classical" music and it is supremely satisfying.  Caveat: my speakers are 4 ohm so the XA 25 can deliver 50watts.

The XA 25 is actually push-pull, but is pure class A.  Pure is a word that I would use to describe the sound.  Do read the reviews, the professional reviewers can describe the sound (actually the absence of any signature) better than I.

It is 100% revealing of the source, unforgiving of poor recordings but displays the glories of the best.

I absolutely recommend that you audition this amplifier.

+1 @vinylvalet   The under the radar gem in amplifiers.

I do not know why people use the phrase “too polite” while referring to Accuphase.   I have no idea what that means.  I have an E-800 and a C-2900/A-80.  They each sound great.  

I have not heard Accuphase amps, but recently added a Pass XA-25 to my system.  I have previously owned the First Watt M2 and Sit-3 amps.  I am using the XA-25 with high sensitivity open baffle speakers (100dB, 8 ohms) and Fritz tower speakers (unknown sensitivity, 4 ohms).  My description is that the sound is enveloping.  Detailed, beautiful.  It digs deeper into the music than my two other amps, a 45 stereo amp and 46 monoblocks.  I love those amps with the open baffle speakers, but the Pass in my system just makes me smile and listen for longer. I also get the sense that it has more powerful than advertised. Also it is built like a tank.
