The big problem with "tuning" via cables rather than simply selecting the most neutral cables is that cables are passive devices and there are clear tradeoffs in any deviation from neutral. For example, you want a warm cable, ok... it won't be as resolving and it will "smear" fine detail. There is absolutely no way around this. I use gold to add warmth in my high end ICs, I feel it's far better vs using copper but the price is higher and there is still a tradeoff. I do feel like a small amount of warmth is required in many system as recording studios generally use warm cables and so playback using a totally neutral system will deviate from what the artist intended, circle of confusion and all that... So I actually have three different high-end ICs depending on how much warmth you want!
You argumentation is centered on two things that are non-existent in stereo - neutral gear and the possibility of listeners knowing what were exactly the artist intentions. However it is very clarifying to know your perspective and how you tune your cables. I have no doubt that people who share your preferences will be very happy with such cables. The Crystal Dreamline cables also use gold to add some warmth - too much of it in some systems, IMHO.
You assumptions are completely wrong, no point debating your fertile imagination. IMHO using the word garbage in this subject does not help a proper exchange of points of view, the winners are the cable skeptics.I feel you're far better off with more neutral cables, clean AC power and choosing the source, amp and speakers from there. That said, it's super rare for anyone to actually do this. It seems like you select your gear using cheap, colored garbage cables with no regard to AC power and then you deal with the rest. The problem is it's all a SYSTEM and doing it that way isn't treating it as such. It's very common for folks to buy a system without regard to the cables and then, when they try neutral cables, they can hear issues with the system they previously didn't recognize.
I think one big issue is information overload and the fact people often can't recognize, understand or define what neutral is. The thought that the cables studios and live sound venues use are the definition of neutral is an example, and it's so common, Ron himself has said he wants to start with Mogami, which is very warm and reduces resolution to a shocking degree vs an actually neutral cable. IME such an IC cable alone can cripple a system.
Nice to see we agree on the impossibility of finding an accepted reference for neutral wires. So all is left is picking the non-neutral we prefer or create a never ending inconclusive thread on cables that we think are neutral.
