“ Some users really enjoy this cable, but I have not read any comments (other than negative) that indicate a realization of significant changes in frequency response.“
I have to wonder at just what is your agenda here!
I have no dog in this fight and yet from a merely spectator perspective you seem to be working very hard at discrediting an audio product that you have neither owned nor heard, your self considered opinion is mere speculation.
In the interest of not appearing so do consider changing your “Some” to The vast majority and your “ but I have not read any comments (other than negative)” to literally The One or Two !!!
