My 2 yen worth,
These are my thoughts from a very brief impression. To be honest I round it hard pressed to tell the diff between the 000 & the BTG cable. In terms of price, sonics, and ergonomic the BTG makes sense. It's not sonically better than the 000 but a $100 cable that sounds on par with a $300, it's a no-brainer.
The only thing though about that particular BTG cable (as that was the only one I experienced) was its durability. It belonged to a friend of mine and initially one channel was partially cutting out. I was told recently that the cutout is now permanent. Possibly it was the rare odd case.
Meanwhile, I'm still on my 000 since I already have it.
Thank you AnakChan!
Always appreciate your input.
