Best cable for short monoblock runs?

My blocks are elevated so that I only need 15" or even 12" of cable. I've done a lot of DIY experimentation with short and more conventional (2 meter) lengths and results suggest the composition and configuration of short runs may be more critical than long runs.

Probably my best short run results were with 4 - #24 bare Cat5 copper runs for each leg, spaced widely apart, like a fan. 8 wires total.

Your experiences, suggestions? Doesn't have to be DIY. Commercial is good.

I've tried Jon Risch's 89259 2 meter runs -- not too impressive, to be polite. I just ordered a 2 meter pair of Signal Ultra cable. I'll use long runs over that short 12-15" distance if results are superior. May as well put the blocks on the floor if I do.

I'm using DIY monoblocks now but have a pair of Clayton M200s coming soon.
Regards,
Dave

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?

Steve uses all silver. The Grover Huffman cables are a combination of copper and silver ribbons.

For copper I prefer Ohno Continuos Cast, but have had good results from other types as well.

Since I run balanced I'm using longer runs now. For single ended 1m would be my limit.

Wow, a lot has past since I introduced the copper ribbon. I teased my 12 gauge ribbon from a Goertz 12 gauge ribbon inductor. It is about 2 inches wide, .003" thick, and all nines pure.

I use plain old Reynolds Aluminum wrap cut into ribbons for the return to the amp. Yes, aluminum sounds ghastly. The amp has never complained though. :-)

Interlochen - Most of AQ stuff is 99.9999% pure and some is 99.9999999% pure copper. Some manufacturers like Acoustic Zen in addition forge copper into hot forms (continuous cast) to prevent crystal formation (impurities reside between crystals). It has zero crystals (one continuous crystal) while standard oxygen free copper has about 2000 crystals per foot.
