Yup. I heard a difference with my KZ AS06s. Inexpensive (35$?), but full-balanced drivers. Copper cable (Tripowin Zonie even, I think) versus the 35$ “silver” cable above. I did not believe the cables would make any difference, I bought the cable because it looked good, and I actually wish it would not have changed the sound signature, because I’m treble-sensitive and the subtle “sparkle” added by the silver cable just adds a bit of sibilance and “air” I don’t like.
Man I also hear the “interiors” of my old smartphone working with the KZ AS06s, lol. They’re not detail monsters, but it’s funny hearing interferences going through, sometimes, like, when a page loads. Yup, BA drivers, even inexpensive ones, are sensitive!
Long story short, everything matters… but Amazon basics cables are still excellent. Lol. When I bought my first speakers, I only had tiny, thin cables to plug em. Monoprice 12AWG oxygen-free copper cabling arrived, and the speakers gained like +5dB bass.
There’s a reason why oxygen-free copper is the standard. I feel like everything else is like… adding tubes to your sound. Sometimes subtle, sometimes extremely different stuff, different materials, will just add a different flavor or mess with the sound. In fact, I already said in this forum, “if you believe different materials make a difference, chances are your favorite cable might be at the dollar store”. Silver is more conductive than copper, but uh, yeah, quite rare, quite expensive.
TL,DR:
-My bet would be on silver for achieving “perfection”. Why? Science.
-Until then, oxygen-free copper is perfection.
-I stay away of companies not mentioning what materials they use. Be it Monster cables or Audioquest.
