@jsoku I come from SET Tube Amplifiers for over 21 years. I love them for their glorious midrange. The XA25 was purchased from Moon-audio.com on a 30 day trial with a 10% restocking fee if I returned it, but my good buddy whose an audiophile said I would really like the sound of it. I read a few reviews by Terry London et al and his equating the XA25 to a SET amp really floored me.
When I got it setup and heard the first 30 seconds even cold out of the box I was speechless and instantly smitten. There's a tonal purity and inner detail in the midrange that leaps out at you with an immediacy that gets your attention right away.
The bass is very tight, the highs are sparkly. It begins to open up as it warms up and relax it's presentation becoming more and effortless as bloom on the instruments increases. The midrange is now starling realistic and as good to my ears as the best SET amplifiers. THIS is the cheapest PASS Labs amp XA amp and it has the best damping 500, slew rate 100v, noise 50v, and it's 50w class A power envelope is at only .1% distortion which is incredible into any impedance . It can even do 200w into 2ohm momentarily too.
Only 4 massive matched transistors per side, a completely singled ended class A topology through and through. It's a definite keeper for me.
You can find them used for $3000 and you might find one on Hifishark on there right now if it's still there.
I highly recommend the XA25 AMPLIFIER. IT'S PURE MAGIC!
