I never used word “faithful”. That’s one.
Two - this thread is a clickbait. The OP doesn’t have a set of premium speaker cables that are 1ft too short. He was implying that using premium to connect speakers that use lesser quality internal wiring makes no sense to him. That’s all there is to it.
I’ll answer your question now. I normally refrain from using terms like neutral. We don’t know what neutral is. As far as I’m concerned there are no “faithful” cables. Every cable will color the sound to a certain degree. I’ve heard cables in my system that rendered tone of instruments and vocals completely unnatural.
In addition, we weren’t there to hear instruments or vocalists in the studio to have a point of reference. So neither you nor I can call out any specific cable as faithful.
The way I approach is simple. Get the best possible components and speakers, get your room acoustics right and then try different cables. Whatever sounds the most natural to you and gives you goosebumps that’s the cable for you. But there’s always room for improvement.
Your logic with cheap wires inside speakers negating all possible benefits of quality upstream cables is faulty. Going by this logic we should not even worry about quality of components upstream. So amplifiers, DACs, preamps have zero to minimal impact because ultimately cheap wires inside speakers will just completely negate all of it. If you don’t agree with it, ask yourself why better cables wouldn’t natter.
I’ve been at it for a while now in this hobby and tried plenty of cables. Price isn’t always an indicator but in most cases good stuff costs more.
But then you have another variable. You. Can you hear these differences? Are they enough to justify the purchase? Some people just don’t have the ear.
