Esoteric Audio USA speaker cables


I've got an old (and I think rare) bi-wire version of Accu-path speaker cable from Esoteric Audio USA, which I like a lot, but I cannot find any literature online.
May anyone point me on eventual site expert of this brand?

If anyone tried them, I'd like to know differences between Esoteric Audio USA Accu-path and Ultra-path cables. I see also in the market some Esoteric Audio Ultra (without "path" in the name) cables. Are they different from Ultra-path?

Which would be a comparable (or better, of course)  cable of today production?
Thanks to any opinion.

I exchanged some emails with Acro Japan (Acrolink), and we found that there is confusion between the two Esoteric brands:
- Esoteric Audio USA
- Esoteric (Japan, a TEAC company).
Acro Japan made cables (the last ones were Mexcel) for Esoteric Japan, and has nothing to do with Esoteric Audio USA (which they didn't even know existed).
It seems that Esoteric Audio USA was acquired by MTX.

I had confirm today, from  MTX Audio, that Esoteric Audio USA was acquired by MTX Audio in 1999.

Production of Accu-Path cables by Esoteric Audio USA stopped the same year. There is no equivalent in today production.
