Thank you everyone, I truly appreciate your experience and advice. Now, I know where to go from here, I guess I will look for a used pair of AN silver E or open baffle speakers.
Silverline SR17 Supreme (USD $7500). I'll have a review coming out imminently, but I believe this is one of the premiere speakers < $10k for reproducing acoustic music. Not the best at electronic/harder music, but great for e.g. classical and jazz - very organic and balanced with just a hint of warmth. Very high resolution too, without being too fussy - a forgiving load and easy to match with both solid state and tubes.
I'll add another possibility here, which is that the audio magic you seek may lie more in the recordings that you choose to play than the equipment on which it is played. There are many brilliantly recorded albums that playback on even somewhat modest systems with a spooky, they're in my room, realness. It could just be that your sources aren't that great to begin with and nothing is going to make them sound the way you'd like. I know I have many albums that are disappointing from this standpoint. I still listen to them because I love the music, but it doesn't give the wow factor.
