Do you really think that this system would sound better than this one?
Switch all the cables for cheap $50ish ones > A cd player at half the cost > m-matrix amp (250) > hd800 with stock cable (1500)
Sure getting better components will improve the sound, but its all relative to what you're using. Even on the a 500 cdp and 250 m-matrix or lovely cube amp i'd argue the hd800 would sound faster, more detailed, with a bigger soundstage and more realistic presentation.
