Please feel free to tell me if and why this would be CRAZY, but... I have a modest HT setup, fairly low budget. A friend of mine who's way more into audio than I am is all hyped to come over and play with ETF on his notebook and get my room all dialed in. I'm interested, and think it would be fun and educational as well as effective - however my setup consists basically of an Onkyo 601 driving some older Klipsch speakers and a Polk powered sub. I'm not using any "components" and so really the only thing we can stick a (line level) parametric EQ on is the sub channel. However after thinking about it I came up with this insane idea. What if I bought six of those really inexpensive little parametric EQ's they make for automotive use (presuming I could find some that do speaker level) and then hooked them up to a nice DC power supply and shoved this in my rack? I could run each output channel from the Onkyo through one and have an amazingly tweakable system for only about $200 or so more than I've already spent. Is this nuts? Are high level EQ's just evil in the amounts of additional distortion they introduce versus low level ones? Is there a fundamental reason not to do this that a n00b like me is missing? Thanks a ton for any advice (or well-explained hearty laughter).
