Grannyring and Mikirob, the 6-foot long SCs are already constructed using Cardas GRS spades. They were burned in for over 2 days on the Audiodharma cooker and then for another full day in my system with Ayre's Full Glide Tone. They sound very good and I doubt the spades made much difference one way or another since the signal also routes through two sets of Cardas binding posts, at the amp and speakers. I do believe that running the cables as an external bi-wired pair, doubling both the MF/HF and LF runs (4 wires to each) for less resistance, using the larger 14awg wire for LF while keeping the 16awg for the MF/HF, and the closely spaced/twisted quad geometry (which reduces inductance), all probably played a positive role, particularly since I am driving moderately efficient (but known to be power hungry) speakers using a powerful high current amplifier. I suspect the aggregate 13 awg for MF/HF and 11 awg for LF is more than adequate for a 6-foot run but I would be interested in hearing even larger versions of this wire.
Regarding the ICs, I cannot use the same connectors as everyone else here because my system is fully balanced - so I need XLR connectors. The two I mentioned, Furutech 601/602 and Vampire XLR, are connectors I have on-hand for cable projects, so would not cost me anything. I looked up Switchcraft XLR connectors and the pins are listed as being a "copper alloy." The Vampire connectors are also listed as having copper alloy pins. The Furutech connectors have beryllium copper and phosphor bronze pins that have been treated with Furutech's proprietary Alpha process, which includes demagnetization and cryogenic treatments.
I would have no problem ordering Switchcraft XLR connectors from Parts Express since they would only cost me about $35 for all 8 connectors (I am making two pairs of cables) but I am skeptical there would be a sonic difference between those and the Vampire connectors, since the signal will be traveling through high quality Cardas XLR connectors at the amp and preamp. OTOH, the Furutech connectors have improved the sound of every cable I have used them on.
I appreciate that Mr. Shirokazu Yazaki and Jeff Day brought these good sounding wires to our attention (and that you guys have shared your findings so prompting me to give them a try), but I am not of the belief that the configuration and connectors they use are the only ones that will result in good sound. The laws of physics still apply. I don't mind being the Guinea pig for trying things differently and I will report back on what I hear.
