I have had two speakers that I could recommend. Currently I have Focal Micro BE speakers with an Electra sub. These speakers are effortless and have a great sense of space. I thoroughly enjoy this speaker. Footnote: they do take awhile to break in so make sure your demos have a few hundred hours. Also, they are not forward sounding at all. You get the sense you are hearing everthing without being too artifically detailed.
The other speaker is the Wilson Benesch ARC. Not as much top end extension (air) but the bass is deeper (not better). Very coherent. I think the WB can play at a louder level (not a real benefit for me). Both are easy to drive. Both have a teriffic midrange. I could live with either. See if you could listen to both. Not sure of your electronics but both work very well with tubes (I use BAT separates) Good Luck
