I’ve had the Pass XA25 for 4 years. My speakers are 100dB and could be driven by a small watt amp but I like this sound. 3D sound stage, quick, clean, natural and easy to listen. This amp is made without the usual 2nd harmonic distortion signature that Pass usually has(correct?). Single ended and plenty of power. Note: I use a passive preamp so it is all the amp that makes this nice sound. I have been tempted to try a tube amp but wouldn’t want to spend a lot of money so I doubt it would "beat" the Pass in my system. Another consideration is tubes. Since we have banned Russia this has pushed valve prices up. I saw a pair of tubes the other day for $2500 or so. I know you don't have to spend that but I don't really want to fiddle with my equipment all the time.
