Thanks for the recommendations. My speakers are Sehring 703s (86 dB sensitivity). The preamp is an old Aesthetix Calypso. My current amp is a McIntosh MC275, which I generally like, but it doesn't offer up very convincing bass with my somewhat bass-shy speakers, heats up my living room to an uncomfortable extent, and seems to have raised my monthly electric bill quite a bit. So I am thinking about downsizing to a less expensive solid state amp that might sound similar to the B&K I used to own, but is newer, more reliable, and will be serviceable if the need for repair arises.
Current production "budget" warm/dark SS amp?
Are there any class A/B solid state amps that are currently in production (or only recently went out of production) that are known for having a warm/dark sound that can be bought used for under about $1500? I used to own a B&K 4420, which I liked quite a bit for its warm/dark sound signature before it died on me. That amp retailed for around $1,100 new but went out of production over a decade ago, I think. The other amp I am thinking of is the Audio Research 100.2, which also went out of production years ago and was known for its "musicality". Are there recent- or current-production solid state amps that are similar to those amps but are NOT Class D, don't cost a fortune, and are not 90+ lb. behemoths?
