You bring back a lot of memories when discussing separate Eq's. Prior to the rise of Home Theater, I had a couple of stereo EQ set-ups and they allowed quite a bit of tweaking but the problem with them was they generally added quite a bit of noise.
The only company I ever saw that came out with a Home Theater multi-channel (7.1) EQ separate was "Audio Control" and they wanted big bucks for it, let alone the horrendous increase in cabling that would be required. Also, it was really only useful if you had "separates".
I guess with all the built in EQ's in AVR's and Pre-Pro's nowadays, these units have pretty much disappeared from the scene. If you are still interested in acquiring an EQ for stereo listening you might want to look at the "BBE Sound" website since they have 15 and 30 band stereo EQ units primarily designed for recording and live performance set-ups that could probably be adapted for home use.
