cool, thanks for your input. I have seen and read several threads about longer IC's vs longer speaker cables, but most of those discuss runs or 30+ feet. which is why I asked if there would be noticeable differences when dealing with shorter "normal" lengths. As you say, there's only one to find out. but it'll probably be a little ways off before I try anything else out.
oh, and you very well might know me from etree. I've been posting a lot of new, uncirculated sources for Phish shows on bt.etree recently.
