SirSpeedy, addictions are tough to kick...
You've got to ween yourself down a little at a time - cold turkey can kill ya'.
I've been slowly walking myself down the crossover point and volume range steadily. Surprisingly, the difference is increadibly subtle for such a large output difference.
But, as you suggest, lower levels allow more detail to sneak through. I also moved my subs to the corners(obvious, but I never tried it) behind my mains and moved the mains further out from the wall.
The corner loading actually reduced bass output from the between-the-mains position substantially. But, it also cleaned things up nicely. The lows aren't as obvious as before and blend well with the rest of the frequency range.
Corner ubs and mains farther from the wall created what my system has been lacking since I upgraded a few months ago - DEPTH!
Before, it was wide but flat. Now, I am beginning to get a sense of the distance between performers on stage with good recordings. And I get touches of that 3-D effect at times.
I tried the Cardas Golden setup, but that really wasn't any better than other positions and essentially rendered my living room useless with the speakers almost 7 feet from the front wall and my seating position 6 feet away. That's way too close for 6 foot tall speakers.
I hope to get a couple of other fanatics over to my house this weekend to help with positioning. It is just too hard to do alone with speakers this big. Get up, slide them a few inches, measure, re-measure, slide them again, sit down, listen some music, get up again and again and again.
After a while, it becomes impossible to tell the diference between positions. Yet, I slug on in the spirit of this crazy hobby.
