Go to Immediasound.com and read the Audio Physic speaker placement guide. It's a different approach than most others. Also, try the Cardas.com speaker placement, which is opposite of Immedia's approach. If you get the same results, it's your speakers or music your listening to. I used to use Cardas i/c's. They are fine. You should try their speaker cable, you'll be amazed at the step up. Might be best to keep the same brand of ic's and speaker cables, they tend to complitment one another.
Widening my soundstage
I can't seem to get my Spendor S-100s to soundstage any wider than the speakers themselves. They're off all walls. Been toed in, toed out, placed on axis, moved, tilted, turned, twisted... Powered by Jolida int. tube amp. Arcam CD. Cardis interconnects. Speaker cables = weakest link = heavy gauge Monster cable copper. Could that be it? Suggested repacements????
