Usage:
I use these for putting my rack equipment together - patching fx loops, feeding poweramps, etc.
Quality:
Signal quality is astonishing and you can really tell the difference, especially when a/b testing overdrive/distortion guitar signals. Clarity goes through the roof and the overall sound becomes really tight and punchy.
Personal Thoughts:
I used to think cables don't really matter that much especially for signals at line level but after checking these out I see i couldn't have been more wrong. If you want an upgrade for your setup, this is a must to consider.
I wish there were longer versions of these cables, though.
Conclusion:
High quality cable well worth the money - get one, try it out and I'm sure it will stay with you :)
