Lak, I did not try the Pure Note speaker cables.
Lgregoir and Jcbtubes are absolutely correct. Every system will behave somewhat to much differently to a given cable.
With one amp, the Audience Au24 sc's seemed to strip away some of the dynamic punch in the bass regions. With another amp, I heard dynamic and robust punch and PR&T like I've never heard before.
But in both cases, the Au24's cleaned up a decent amount of grain and time smearing now evident in my previous cables.
-IMO
