HAVE CABLES EVER TAKEN YOUR SYSTEM FROM SOUNDING JUST OK TO SOUNDING GREAT? Experiences ?

Yes

15 years ago or so I auditioned the Shunyata Anaconda interconnects and speaker cables as an upgrade to my JPS lab superconductor+
(well regarded)

The improvements were so dramatic. I remember thinking if I have to mortgage my house these are not going back.

and they did not go back

about $12,000 at the time which was quite an outlay for me

didn’t regret it for a second

Worth every penny

Don’t mind anyone commenting but if you don’t believe that cables can make a difference.  Good for you. But it’s not a place to come argue about it. This ain’t the thread for you.

No, because that doesn't happen if you're already using OFC cables at the proper gauge for the length of the run. Period. Anyone who thinks otherwise is lying or willfully ignorant. Science always beats snake oil marketing. Well, it should, but you'd never know that based on some of these replies.

More like, "Now that's more like it", is usually what I experience.  Nothing otherworldly.
