looking for an integrated amp in the $1500 range

Agree with @perkadin that if you’re looking for better low-level listening you’re better off with higher-sensitivity speakers, and they don’t need to be floorstanders.  Speakers that are easier to drive tend to open up easier at lower volume levels, and I highly doubt you’re gonna find what you’re looking for driving your speakers with a $1500 amp.  Put another way and more directly, I think you’re barking up the wrong tree here in terms of what you’re looking for.  I’m no expert in high-sensitivity, easy-to-drive speakers from the likes of Klipsch, horn speakers, etc., but I’d be looking there first, and it’d also open up more options for an integrated amp as you wouldn’t need nearly as much power.  Just my $0.02 FWIW, and best of luck. 

Thanks Jl35. Interesting but over my price range unless used

Thanks soix. It's just that I don' want to be selling and buying more than I can least do. 

If you want to waste your money, buy an amp.  If you want to solve your problem, get higher efficiency (93db and higher) speakers.  Buying a bigger or more powerful amp will NOT help low level listening. 

Thansk stero5. Normally I might go with that, but I'm just trying to downsize.
