"warm" solid state integrated amplifier

Jesus the guy wants a warmer sounding amp and millerlightcarbon comes in suggesting to get some nice warm sounding springs instead. 
 

Go with the springs dude it'll solve ur troubles for sure! I hate it when my damn springs sound like crap!

Place rocks on your components 

The Boulder 866 leans to the warmer side. Also very neutral. 

I want to second the recommendation for the Krell K 300i. I have been using this amp to push my Maggie 1.7i speakers for over a year now. The power is produced via a patent pending new circuit design called Sliding Bias - this keeps the amp in Class A power longer and running cooler than other Class A designs. It’s midrange on vocals is unsurpassed in it’s price range.

Happy Listening!

The usual gear or tweaks/room dilemma seems to have arisen again on this thread. I don't see why they're opposed. The OP is looking for a warmer sound.

We don't know the extent to which the OP has dealt with isolation and other tweaks, nor do we know the kind of room being dealt with or that room's treatments.

If I was the one posting, I would be ready to invest in a new amp only after those other factors had proved ineffectual. Because then I would know the true sound of any amp being tried. I see no reason that this is a dilemma. It's a sequence and we don't know where the OP is in that sequence, yet.
