After reading Gerry's comments, I think that a good pair of earphones might be the ticket. They are way way more resolving than almost any speaker. (like I can hear any garbled lyric no matter how mumbled with earphones, but seldom as well from my Magenpans)
Also, the problem of resolving individual instruments in a complex passage is more mind concentration than the fault of the equipment.
IE: Can you do the task listening to a live performance?
I can remember as a teen listening to a symphony and starting to follow just one instrument through the whole thing. I would always be in some quasi trance state doing it! Like my mind was fascinated with that instrument at that moment. And I would snap out if it and wondered how I did that. (I no longer have that nice ability.. it seems I lost it in my 30's)
Back to a stereo that can do the job. As I wrote, a CONDITIONER can help a lot in upping the clarity quotient.
