Off the top of my head the sweetest sounding in about that price range would be the Rowland Model 2...but this suggestion might not mean much not knowing what speakers are being used.
HELP: I need a solid state amp with a tube sound
I am very much into tube amplifiers, but it seems that they need alot more maintenance than SS amps do. Is there an amp out there that will get a good tube sound, but with low maintenance of an SS amp? I am working on my budget and I will probably spend about 2500 for it. I already have a tube pre-amp that I like, a Zen ZTPRE, and does a good job for my needs.
