As I read from the website, new batch of TG!334 are going to use 006 cable too, no info for the mh334 though.
Too bad, I really liked the 001. It was my favorite cable with the TG334 and 335SR. I tried other cables but always liked better the sound of stock one.
The 001 is hand made and the 006 is not. That's why they switch the cable I believe. The 006 seems to be faster and easier to build.
