WARM 5 channel amp - suggestions?

With a budget of $2500 ish (could go more, or happy to save less) but nothing outrageous either direction - if you needed a 5 channel amp what would be your suggestions for an amp. Could be new (based on street prices) or used (I'm open to it if in solid shape).

I DO believe there are sonic differences in amps as I've done enough a/b testing DB matched etc. I don't think differences are great, but I do believe differences exist. I don't need a ton of power (call it 100-150 wpc) and I'm good, but more certainly can't hurt.

The other thing, I'm not real big on fan cooled amps.

Thanks.
