I have a few similar cables and for me the change in sound wasn't desireable. The highs are rolled off slightly for me. I would suggest not to go for cheap cables and buy something decent but not very expensive. If you really want the cable to make a desirable change to the sound . If you just want to tame the highs then it's a different matter altogether however for that I'd go with a good quality pure copper cable. Sorry for the rambling.
What I want to ask is whether the newer batch is rid of QC issues?
My blue replacement pair have been problem free.
