So it's either the OP is hallucinating, or wasting money on cables that cost pennies in parts. That's the gist of what you are saying, right?

The brightness/detail (and harshness) was likely an unstable amp with your Nordost that went away with cheap cable if I remember. The "Transparent" has a few dollars (or pennies) of parts to address instability in wide bandwidth amplifiers.
That detail was just high frequency emphasis ... It was not real. That midrange - upper base punch is because you are now hearing it properly without it being masked by high frequency "hash".
Do you have anything to say to help the OP on this? Other than just denouncing cables as snake oil. What is the purpose of your participation in this thread?
