Improvement in Musicality for home theater system

That is a hard one. The problem is surround processors are dense digital electronics in a tiny box. Not a place to create a musical signal. Most musical systems are simple two channel tube based systems (or very carefully chosen solid state). The easiest way to do it would be to use good tube preamp and bypass the processor for music. I would think that another possibility would be a very high end (like $20K… really expensive) surround processor and warm musical amp. I have not been in the market for a while, so I can’t point to a solution. But obviously this wouldn’t be much help anyway.

Primarily it is rhythm and pace. The attribute that connects you emotionally to the music… typically it makes your foot tap… or get emotionally consumed by the music. 
 

it is really easy to get side tracked into hearing more details or more slam and bass, these can lead you away from really natural and musical sound. It took me nearly forty years to be able to immediately sense rhythm and pace. Tonal balance, detail etc are much easier to sense and in many ways much less important.

Typically, one’s foot is a good measure of the musical connection. This is an effect that I noticed in myself and have observed and discussed with many others over many years. Not everyone will necessary be moved the same way. Certainly it depends on the source music as well.… if the music is not compelling it’s reproduction is not. This is my generalization.

Also, some audio folks actually are not in it for the emotional connection / the music itself. I have known a bunch of folks over the years that are in it to experience analytical listening… to marvel at the details and sound space… they are not actually moved by music.
