but honestly... if a CD player is plugged into your integrated amp using a digital connection, the player doesn't really matter (unless it's a real piece of you know what). If it's sending the stereo signal analog, then the player does make a difference because it is decoding the 1's and 0's into music.
i'd buy used stuff, a safe 500 bucks for both the player and the amp. you don't want bad electronics ruining such good speakers.
