Allright. Enough of looking at bigger amps and more expensive receivers. I want to make a purchase that is going to make a significant sonic difference in my system. So I figure that if I can buy something that will flatten out the nulls and peaks in my frequency graph I would be making a wise purchase.

So here's the question. Is the BFD that is frequently mentioned around here really going to help me? It would appear that it is for two channels, so what about multi-channel for music and movies? I read the info at the Behringer site but I am still confused.

How many of you out their have made this purchase and did it make a significant difference. It would seem that if it could flatten out the frequency response that it would be one of the best additions to any system that you could get.

Any help is much appreciated as always.
