Has anyone ever tried cables made with OCC (Ohno Continuous Cast) Copper?

As others have pointed out, OCC copper does sound better (transparent, detailed and smooth) than anything I’ve tried.

My system is wired with Audio Envy cables which uses OCC wire and priced reasonably.

Lately, I've been preferring the Iconoclast OCC XLR cable over my favorite for many years, the Audioquest WEL. 

It does all the right things with regard to frequency extension, silent backgrounds, bass weight, smoothness, etc but I'm finding I'm really liking the way copper contours the sound in a different way versus silver.

I had high expectations when I tried a pair of OCC copper interconnects. They were very transparent and hyper-detailed but lacked body. There's obviously more to cables than just conductor material.

I added WireWorld OCC cables when I ordered my Emerald Physics KCIIs, which I replaced with EP 3.4s and replaced the speaker to outboard XOs to WW OCC jumpers, after a few weeks of listening to shitty supplied jumpers. No contest

HTH

Recently made a pair of vh audios v-twist with eti connectors...im rounding the suggested hrs burnin (which is a lot) and nothing lacking here...just nice clean,no hyper detail...great sounding pairing.
