I had the same problem with music being forward and went through a lot of cables (Nordost,Mit,Monster,Synergistic...ect) and changing the souce (cdp) 3 times.
I eventually just gave up on trying to get better seperation as each change I made was not to my liking.One day I deceided to run a toslink cable from my cdp to pre and let my pre/pro do the d/a conversion (Rotel RSP 1069).To my surprise this gave me what I was looking for.Music was now more detailed and airy and seperation was amazing.Instead of having a wall of sound I could now pick out each instrument and it being a toslink cable I thought it would end up on the bright side but it is just smooth , detailed and a more realistic listing experence.
