I have owned XA25 for 5 yrs. 25W Class A and it has over 80 W output capability. I bought this brand because of reliability. It is overbuilt! It weighs 49 lbs. It gets warm. I have 100dB Klipsch Cornwall clones. I use a passive preamp. The sound comes through neutral with dynamics, clarity, great soundstaging. This is the only Pass Labs built single ended.
I have heard Luxman solid state. It is warm and luscious. An attempt to have a tubey sound. This is not a bad thing. Not sure who services them in the US.
Accuphase is near the top for solid state. It is just a natural beautiful sound. It has been a long time but Accuphase and Klipschorns were memorable IMO. A very small dealer network and not sure about service.
All of these companies make very nice equipment that you will not get tired of.
