I really like these cables. They are solid build and sounds great. I use them from my Allen & Heath Xone 96 mixer to external effects and back to the mixer again by the send/returns.
When I'm using them, I can't hear any noise in the sound and that is really important to me.
Another important thing is the quality of the cables. I have these cables plucked in and out at every single gig I play as a DJ and not a single issue with them after almost three years now!
