I'm curious then when you mean more open in the sound stage do you mean a wider sound stage? That is one big issue I had with the 334 was the closed in sound. Great depth but lacked much of any width to its sound stage. Perhaps the 000 cable adds even more depth to the sound which seems to be soullinker's cup of tea ;).
Having owned the TG334 for many months, I don't think it sounds closed in at all. Simply put, it sounds real. Not wide, not closed in but simply real and proportionally accurate.
