@bondmanp FYI the Silver Litz RCA's that worked so well for me are from E-bay. They are MS Audio, Sunnytoto or Sunny Audio is the E-bay store. They were a bit cheaper than the MA4's with cu. Eichman's, but are a big,big step up overall. I have Cullen XLR Interconnect's which I find good, although unlike RCA Interconnect's I hear little difference between XLR Cables but extremely significant differences with RCA Interconnects. I recommended Cullen Speaker Cables to an acquaintance and he purchased some Cullen RCA's as well, said they blew away his Van Den Hul's. So while the MA4's were a step up up from what I had previously (4 years ago), and still reasonable value when heavily discounted, I have now found better at the right price.
Getting back to Speaker Cables, having Mono Blocks with dual Speaker Outs, has been a revelation regarding running Speaker cables, Running dual Speaker Cables just gives so much flexibility in allowing different combinations, I find the SP7's bass master's & the Cullen's absolutely outstanding value for money on mids/highs (when used on bass performance was adequate,but not at the level of SP7's). Much better results than Bi-Wire cables that I have tried.
