Best cable for short monoblock runs?

There is no better cable than Anti-Cables. They are cheap, but simply get out of the way.

Stringreen, actually there is for short runs, and it isn't commercial. Cardas is just awful, if you insert it anywhere in a really revealing system. I know, because I tried it. Of course, if a person's amps throw off objectionable HF sounds....

I use very thin, .003" 12 gauge copper ribbons lightly wrapped in Saran Wrap to prevent shorts. The sound is thrilling in it's stage depth, and optimally realized bass and treble extensions.

Ribbon cables are a good solution. Two non-DIY brands that come to mind are Decware and Grover Huffman (which I'm using in a 2m run). They are both available in 1/2 meter runs, and longer if you decide to go that route.

Stringreen: I've considered anti-cables and will have another look.

Clio09: I've seen Grover mentioned frequently but I didn't know Decware offered cables. Mmmm...

Mural: 3 mils ribbon. I assume the 12 gauge refers to total cross section in the ribbon case so your cables must be wide-ish, which is not a problem. Your ribbon source?

Yesterday I installed 15" lengths of RG-8x, single lengths per channel and I think it may best everything else.

Obviously I'll have to try multiple commercial offerings and hope for a return policy. I've exhuasted DIY alternatives except ribbon.

I wonder how Al foil would sound? Probably ghastly.

Finally, what do you guys think about short vs long for monoblocks? Convention holds that shorter is better for SCs and ICs, but in this case long SCs allow for shorter ICs, which may be more critical. Not sure.

Also, curious about copper purity. What is the high-end standard, 99.9% -- or better?

Side note: 7 nines is the only way to get warmth out of silver. Anything less will be bright. Heard this?
