@OP,
Yes, cables (and just about all equipment) benefit from a 'break in'. I guess it just gets those electrons moving in sync.
I'm glad the AQ cables are working for you. They are a good company.

Gdnrbob,thanks for reply!I do like AQ 

I do like Aq.  I have their speaker wire as well and have no desire to change.

Bill Low, AQ designer, has done a great job for many years at offering cables in the line that provide incremental steps up in performance.  As you move up a cable you either get better conductors or dielectric. It comes down to what your wallet can bear.  The sound just is more open and sweeter as you move up.  Bass detail and depth I've found is most affected by the dielectric, at least in their interconnects.  After A/Bing Columbia and Colorado, the difference between the two was the bass performance.  I lucked out on the half price sale on Colorados at Music Direct!!
