looking for a Integrated amp $6,000 range

John1,
which speaker are you referring to?
thanks,
Dan

Luxman. On the used market. You can save a bundle. I own the L-507uX MK2. Wonderful amp. Customer service is outstanding. 

Not sure if your preference is for SS or Valves but I can certainly recommend a used or discounted Ayon Triton III with its 8x KT150’s and Triode/Pentode options.

Amazing tech and build quality, maybe check the manual out online for an insight.

I’ve used it with Harbeths, Escalante Fremont Mk2 and Tannoy Arden Legacy’s.

Ayon Triton III does the business, try and hear one or if taking a risk, it’s minimal taking account of its quality although I imagine a few of the suggestions here fall into that category.

Remind me what your speakers are?

Lots of great choices here.  I love my Mimas.   
Good luck.  

The speakers I’m using are the
 Legacy Focus 20/20 late 90s version
