 Benchmark AHB2. Reputed to be the quietest amp on the market. Around $3000 used.

Always liked the audiosource amps when I had them, pretty reliable, even when driven hard.

May get flak from this, but they were nice amps at a great price point.

50w up to I think 150-200wpc

nice little amps

always did me well

or find a used one of other brand check the Gon

Adcom 6002 is a nice low power amp with great headroom  

still wish they made their preamp-one. Great preamp, still have one wrapped in storage in basement somewhere.

You might like the Konus Audio Integrale (integrated amp) or Robusto (stereo or mono power amp). Fast, natural, alive.

Here are a few professional reviews:

What’s the budget? 
 

LTA has fancy pants tube amps that weigh next to nothing for 4K+ and are supposed to sound excellent. I can’t see the value there but I don’t know what goes into it but they are pretty much universally praised.
