Integrated S.E.T Amp and Bookshelf Speakers Recommendations

Greeting! When I was looking for a CD transport replacement I received great info and advice here.

Now that les fil #3 is adulting, I have my own office/library/hiding place. I am exploring lower wattage integrated SET amps and higher efficiency (92+) bookshelf stand-mount speakers, with a relatively flat signal response. I listen to lots of jazz; smaller chamber music groups and Early Music; acoustic bluegrassy, folk and the like. 

I'm looking for an amp that can do the following- liquid tonality with instruments; good realism and immediacy with voices; solid 3 dimensionality; sweet and airy treble; and defined decays. I want it all, lol.

I'm going to audition the following because these are names I have read about.

Elekit TU8600R, UnisonTriode 25, Sophia Electric Prodigy Dual Mono. Any others?

As far as speakers-Audio Note and Harbeth. Any others?

Budget-I'm listening and learning.

Anyone have any thoughts and recommendations?

Thanks again!

David
