When looking for used cables, I just check hifi shark. It would list anything up for sale anywhere, even the stuff here on audiogon. A word of advice, go on hifi shark and see if any of your cables are up for sale anywhere and simply beat their price. That will be much more effective than your auditioning offers.
JW Audio Signature Interconnect - I can't get anyone even to try them
I recetntly posted an ad for them on Agon, and it has generated very little interest. I'm offering a 30 day trial with refund if not happy. These cables have been my reference for many years and sounded better than anything I've owned including a pair of $1200 Audioquest silver. I recently found Iconoclast to be incrementally better, but it retails for $1740.
Does anyone have any suggestions?
If a long-time member here with a trusted sales history is interested in just trying them, I will send you a pair if you are willing to pay for shipping both ways. Let me know what you think of them. I think you will be surprised at how good they are.
If you live anywhere near me at 53005, bring your cables over for a comparison. My system consists of a Luxman L590AXII, dCS Debussy Dac with a dCS Network Bridge connected to Canton Reference 8C floorstanders or ProAc Response 1SC monitors.
