I don't see why you are so worried about having your EQ after the volume control and before the amps. Every speaker (except the LFE) in my system is run this way (ie. each speaker has a dedicated 10 band parametric equalizer associated with it) and that alone introduces no added noise, problems, or distortion that wouldn't have been present using a fixed line level. Seems to me that mucking about by splicing into a circuit somewhere is inherently more problem -prone. Or maybe I missed the point of the originl post?
