I used to bypass the amp speaker fuse protection with short stranded Monster cable as fuses. Then I tried solid copper. Each had a distinct sound that was better than the stock fuse.This is not news, P. Aczel(in his first life)said the sound of the Amber stereo70 could be improved if you bypass the speaker protect fuse.I have tried the Iso Clean and for the money they are a reasonably priced upgrade, and still offer the protection of a fuse.
