I am comparing the old highs, to the new highs on my recently recapped speakers, and the new design cables. The highs were just a bit harsh on the old design, after the recap. Now is is a bit softer and not as harsh. I’m betting it’s the copper wire, compared to the silver coated copper wire. The sound is just nicer and easier to listen to. Before the recap, I did not have the harshness. Also, with the new cables and recapped speakers, the system seems to be a lot more recording quality sensitive. Quality recordings are amazing. Less quality recordings are thin sounding to me. That’s it for now.
