Yes I find some changes are easily heard others subtle. I havn't changed to Lush 2 yet kind of waiting for things to settle but now its moved to other cables. I do wonder if Nordost have already discovered what you have with these recent advances with screens. The more I think about it they can only do so much with materials. Mind you when you can afford a 24/7 design team its highly likely you discover things.
I really see the benefits of the Stealth III the source has always been critical in audio.
Xxhighend software still has hidden talents.
