Hahaha! It's always a good topic to bring out the sour pusses dining on sour grapes. My experience in audio has been enriched by listening and trusting my ears. My experience and ears don't match everyone's I listen, or am in contact, with and I can only speak to my experience: the very large number of audiophiles I've had contact with, am in touch with and have sat together and listened on each other's systems pretty much all agree that everything can make a difference - and that cables are, and should be treated as, components. They to take burn in much like other pieces of gear. Trust your ears - you're on the right path in that you are listening and taking stock. Keep an open mind and experiment.
Cary gear tends to be a bit warm in their house sound and that can be heightened by cabling so it depends on the sonic landscape you enjoy. Keep listening and enjoy the tunes!
