This might be an unusual question, but do you know of any receiver that has a equalizer display (like what winamp has when you listen to music, or what some car stereo head units have)? It might be out of fashion now, but I am really into the look where you can see the bars on a equalizer going up and down, etc etc, or various other designs. I'm thinking there probably isn't a receiver with this feature, so my next question is is there some sort of attachment you can add to a receiver that it's only purpose is to produce a nice pretty equalizer display? Perhaps some sort of DJ equipment or something? Please, any help will be greatly appreciated.
