roxy - regarding speaker cables.
I've been out of the flow and the shows and the budgets to audition or live with 'serious' cables for some decades. But the first generation predecessors of those 'Black Pearls' from an 80s CES rings clear in my memory 40 years on. Also, I heard real Black Pearls in 2012 at the Thiel Listening Room when comparing CS3.7s to the newly finalized CS2.7s. The sound was the best that I've ever heard. I didn't peruse the gear, but I have found out that the Black Pearls were the speaker cables in use.
