Well, well, well...where to begin???
First, lemme say that I posted the question not necessarily out of a need to "fix" anything. Rather, out of curiosity as to the "collectives" thoughts/opinions.
For those curious, my systems is composed of the following:
Klipsch Heresy (front mains)
Klipsch KV3 (center)
Klipsch RS-3 (surround)
Klipsch KSW-15 (sub)
I realize this hodge-podge of speakers is not an ideal matched system. But the wife get's her new couches and bedroom furniture first, so cut me some slack here.
For the most part, I'm happy with the sound. There are certain program sources and music that sound overly bright and even harsh from time-to-time, but that I can generally cure with the Denon's tone control. OTOH, I'm not that keen about how the Denon's treble tone control affects the mid and upper mid frequencies.
However, in a former life I've witnessed how a properly equalized system (using a premium equalizer) tamed a room's acoustics. I agree that it's possible to introduce distortion and that one can drive an amp into clipping by being overly generous with boost. But what does one do when revising speaker placement is either not an option or doesn't solve the problem nor is moving walls?? It seems plausible to me that a properly designed, high-quality parametric equalizer set-up to get a flatter room response, using a pink/white noise generator, should not appreciably degrade the sound or ruin the "performance". After all, recording engineers use certain amounts of equalization.
Having said all that, I would also admit that my ears have disliked the sound of a system that was equalized to achieve a flat response.
Anyhow, like I said, just probing for comments/opinions/theories/etc. How else am I ever to get smart??
ps: I too am a recovering dancing lights aholic. Fortunately, my lava lamp keeps the urges at bay.
