Hi, love the system, I can imagine how satisfying it must be, to be able to enjoy it on a daily basis.
Up until a couple of weeks ago, I was using the A 23 Auditorium speaker cables too, but I tried Tempo Electric's solid-core silver in teflon tubing, and I sold the A 23's the next day. Great match with my SET 300B and vintage Tannoy HPD's.
Best regards, and enjoy,
Dan
