Honestly , I put Dave's SCR-14 speaker cables in my system and have yet to pull them out.
There seemed to be an improvement , so I just left it at that..
I would say Tonally there was a slight improvement (not quite as sharp on the top end), I noticed some details that I have never heard before, also my Toes wouldn't stop taping for a couple of days.
I would have to put my old speaker cables back in, to give me more ammunition for more details to explain..
The Cable that I replaced was "CullanCable" Crossover Line With 10 awg Upgrade,
Military Spec Wire
10 Awg 99.99% pure silver plated copper wires
Teflon Dielectric which is extremely Quick and accurate
Ferrite noise suppressor on each 10 awg wire
Teflon wrapped then covered with Techflex Sleeving
Completely Hand built from the Ground up
Made in the USA
I will Have to finish this post later.( at work)
