$800 to spend on speakers, $1500 on whole system

I agree with @soix that you should get a local audio dealer to let you audition the speakers in your home rather than take your amp to their spaces. The thought being that YOUR SPACE will determine the sound you get out of your speaker/amp combo much more accurately than their space.

You mentioned you're in a smaller room. I think that will help quite a bit with the concerns mentioned in this thread about under-powering your speakers. A smaller room is easier to load and will provide some natural gain (https://trueaudio.com/st_spcs1.htm) as well as placing you closer to the speakers when listening.

Naturally you'll want to up your amp game at some point, as the additional power will afford you more headroom, manifesting as more dynamic sound and added transparency, but you have plenty of time. The audiophile pursuit is an ongoing journey, and you've got decades of tweaking ahead of you. 

The chances that a dealer is going to let someone demo speakers at home is pretty slim these days, let's try to be realistic here.  

The GoldenEar speakers do interest me. I know of a local dealer where I can test them at the least, and I plan to. 

I also see a couple pairs of Vienna Acoustics Haydn speakers here on audiogon for sale. Does anyone have experience with those? 

I loved the bach Grand but was disappointed in the Haydn Grand, they were bland to me. A great deal is a pair of Quad 21L that was just posted. The Haydn Grand seems to sell for very little less than the Bach Grand

fortunately/unfortunately there are dozens of very good speakers in your price range...
