Do speaker cables really make a difference ?

Having recently replaced my Blue Jeans speaker cables with Mogami, I can weigh in on this discussion. Two totally different sounds, for sure. After playing the Mogami's for a couple months I was not so sure they were what I was looking for and switched back to the BJC's, big change and I prefer the sound. I will switch back to the Mogami's once more to get a fresh impression, but likely looking at trying something else in the "lower" cost range.

If you wanna stop messing around with entry-level cables, buy these Acoustic Zen Satori cables at a great price and go to the next level.  If they don’t work out just turn around and sell them at little/no loss as there’s a fluid market for AZ cables.  Just do it.  You won’t be disappointed.

Thanks for the heads up, I will take a look.
