I need a speaker system that disappears completely into the room, and when combined with resolution that takes you layers deep into the recording, creates a completely convincing illusion that people are in the room with you.

Ditto! And when non-believers listen they can't believe the the performer(s) are right there in the room.

Mission accomplished!

I don't really care much about soundstage, but tone, beauty, and resolution are all at the top of my priority list.

So how about others. I would be curious to know what is really good sound to you!

Almost always it's what the other guy has!

Clarity acd clean sound

[JackD201]

Ideally, easy to hear into, immersive and tactile.

Given real world limitations, I'll settle for a high level of intelligibility of elements.

a non fatiguing sound. accuracy. tone.

[OzarkTom]

Highly detailed and transparent with 3D holographic imaging without losing the magic. What I currently have now.

I listen to mostly classical (orchestral, piano, chamber music) and jazz.  Instruments are clearly defined and in a space, resonant with accurate decay.  Piano has resonant bass and clear attack in mids and treble.  Drum sets should have different drums in slightly different spaces.  Notes should be dynamic in attack and decay. The recording should also capture the echo of the venue.  Surely that's not asking for much 

None of it matters if the performance is lousy or the music uninteresting.
