Looking for an integrated amp around 4000 to 5000.

The Ayre AX5-Twenty was the most amazing integrated I’ve heard. I got a VX5-Twenty amp and pair it with my BAT preamp but the integrated sounds better at least in my system and with my musical tastes. I believe you can find a used AX5-Twenty in your price range. 

I looked at the Ayre but no line out for my sub.

Klh007 just ready for a change. Part of the audiophile phobia.

Unison Research?

@pal As @klh007 asked, what can you tell us about the sonics you’re seeking in an upgrade that you’re not getting from your amp? I can’t believe (well yes I can) people are just recommending gear left and right without even understanding your musical priorities. People will always just recommend their favorite brands or what they use themselves without listening to you or asking probing questions.

Can you describe the "change" you’re looking for? If you are simply looking for a change then that’s easy - just buying something else....anything else.

And why do you need a line out for a sub?  Many people find it sounds best to simply connect to a high level input on a sub.
