Tvad's suggestion for the Audio Control C-101 Equalizer is good if you can get it for anything like $30. Don't forget that you will need to add a calibration microphone to fully utilize the C-101. I'm not sure what kind of mic is needed, but I have used an Audio Control "Richter Scale" (a low frequency range 1/3 octave equalizer), and its mic was unique.
Yeah! Finally some support! Thank you, Eldartford.
BTW, the C-101 comes packaged with a mic, and this is a question you should ask a seller before making a bid or purchase.
Even at $100, the C-101 will make a more profound, and cost effective improvement in your system than any other change. The formula begins to break down if you're going to spend several hundred dollars on a new CD player. But, I still maintain it's a significantly more valuable investment than a corresponding $100 spent in cables.
