OP
I would recommend that you look seriously at the Prima Luna line. its affordable and sounds good. the Chinese brands can sound good but it’s a hit and miss. some say OK but others are displeased. so, to save grief, just go with a prima luna
look at Upscale audio to see what you like. integrated or separates, it all depends on the investment. The only other Tube power amp (actually integrated) that can compete with the primaluna BUT may take some serious thinking is the Line Magnetic LM-845a but that is another level all together.
Lastly, Look at the Rogue Audio Tube power amps or integrated amp.
for me it's a tossup between Prima Luna and Rogue. I suggest that you do a home Evalutation.
