Don't forget Primaluna, whether integrated, stereo
or monoblocs, they're excellent. I've got the 6s
if you'd like to discuss.
If your system will work Ok with 20WPC, the Antique Sound Labs Wave AV-25 DT (or the older AV-20) is a nice choice. They cost $700 for the pair (monoblocs) new, but could be had for much less used. I've used the AV-20's in an office system for a few years, and they have been perfectly reliable and very nice sounding.
Sophia baby electric was what I tried first - $350 used, but it provided a LOT of what I get through a much more expensive amp now.
what kind of music do you like,how big is the listening room and at what levels do you listen at?
