Knownothing,
Yeah, sorry, the thread's kind of a mess.
To bring some order to it. Bobby Palkovich, owner and designer at Merlin, recommended the 9 gauge, copper speaker wire. Actually, he particularly recommends some flavor of Cardas wire, but that's way beyond my budget. I'd had some Anti-Cable here that was braided into a bi-wire configuration at the factory. Just sold it, since the Bobby P. recommended using his supplied Cardas jumpers and just running the speaks in single-wire mode.
I checked at the Blue Jeans site. They have a Belden cable which is almost there -- 10 gauge. Almost.
I finally found that a company that advertises quite extensively on Audiogon, called Supra Cables (made in Sweden, of all places) has a cable that fits the bill, and it's "cheap" by audiophile standards. It's called "Classic 6.0." It's 9 gauge, all copper strands, tinned to reduce "skin effect." And it's only $72 for a 3 meter pair, unterminated, from the distributor, sjofnhifi-dot-com, or you can also order it from Madisound. Anyway, Bobby from Merlin said he hadn't heard it but it looked promising, so I'll give it a go. By the way, sjofn sells it direct with a 30-day money back guarantee.
