Very interesting. Nice catch.
This most definitely sound like it's done on purpose if it's present on both the cables that come with the frosted and stealth. It's indeed there on my cable. I'd like to hear the rationale behind this decision actually.
Do you hear any significant difference in the sound when swapping out cables?
This could make many cable comparisons here with the stock ASG-2 cables useless...
Very interesting indeed...but it seems like such an ordinary cable. I'd test it myself, but I just shipped out my ASG-2 for a loaner.
