i have my 80's bi-wired as well, And no i couldnt tell a difference either... However, the 8 gauge 4 conductor cable im using is as big around as a hose, so i just decided to leave it because it looks alot better than my skinny little AQ type 4's.

And hey what the heck, differnce or not i figure the bigger the better. And no I didnt pay alot for it. Nothing infact. It was used when we had a 13KW generatator, It provided the power from the generator to our entire house. I figure it does the job.
