I got an LFD LE V Plus from Gene Rubin Audio for about the top end of your price range (it was on sale). (the 2018 version is $4,995). Get on their mailing list, there are specials occasionally. This amplifier is (very) long on punch and musicality and very short on features (no remote). Build quality is good but looks (and is) handmade. I'm driving B&W Nautilus 805's and I think it sounds every bit as good as my other system, which is AR VSi75 driving big Thiel's. Different, of course, but I don't think it suffers in comparison at all. Very highly recommended.

There is also the LFD Mistral Plus with phono stage ($3995), that I don't personally know anything about. The LE Plus does not come with a phono stage.
