Hi Jon,

Thanks for the reply! OK, well that's annoying, as I already bought the cable specified on the TNT website from my local Maplins (I live in the UK) the stock number was the same. The foil looks decent enough to the eye at least- is there a specified thickness I could check with a gauge, if the production runs are so hit and miss? I must say, it's a good job I happened to post on here about it if there are issues which could cause potential damage- one would think the guy on the TNT site would be responsible enough to update his site and inform people the cable is no longer suitable.

Anyway, OK I hear what you're saying about the stranded construction, but it was one of the main reasons I was interested in a UBYTE-2 build, to be honest. Although this seems like a good opportunity to ask, since we're on the subject of stranding ;) because I've heard so much negative about it and yet some of the best speaker cables seem to use it, e.g., Kimber. I think they use a technique called 'varistrand' where each small gauge conductor has strands composed of different diameters to 'spread' skin effect over different frequencies, or at least that's the theory. What I've never understood, and it also applies to the braid example in the Belden you describe, is won't all the little thin wires, which aren't individually insulated, just short together and act as one bigger conductor, and will you get tiny distortions as the wires short? Maybe you don't, I'm just really curious for an explanation! I've noticed that even Kimber have started using solid core on their highest range interconnects and speaker wires now.

I suppose the other alternative is ro use the cable with the foil AND copper mesh in place?

Coming back to the foil only construction type for a moment, has anyone found alternative foil based coax? There are so many on the market here using pure copper foils and foamed Teflon dielectrics. Regarding self winding the cable in copper, the UK site hificollective.com does sell copper foil in various sizes for audio use (Mundorf brand, if memory serves), so that's a possibility I suppose, although that seems like it would be quite a job, would anyone who's been there and done it care to comment?

Best regards
