Ken,
One player that is sort of under the radar in your price range is the Original CD 2008 modded by Moon Audio. I believe you can audition this player to see if it works in your system. I did, and ended up buying it. If I had to describe its sonic attributes, the description would be very, very close to just what you have said you are looking for. It is not a tubed unit, but does use Lundahl transformers, which seem to impart a very pure and natural quality to the music. It has very nice imaging, excellent detail retrieval, and that certain jump factor.
There is a review by 6 Moons on this player, which pretty well sums up the player's performance, IMHO. I suggest contacting Drew at Moon Audio for more information. All you have to lose is the shipping cost if you don't keep it.
I have no financial interest in the player or the company. I just couldn't help thinking that it sounds like a match for your situation.
Best of luck.
