Edit: After reviewing the responses I sat down and really gave my system a listen with my eyes closed to try and get a better understanding and feeling of my thoughts and what Im looking for.
After about of an hour of listing what I came up with is as follows:
Everything sounds very good at a lower volume. Once I get in the groove and start to turn up the volume things start to change. I noticed the music starts to get flat, no real separation in instruments. Vocals sound strong clear. So is it the speakers , source, amplifier that is limiting what I am looking for?
