A few years ago, I went down a bit of a rabbit hole trying different speaker cables.
From 16 awg to 12 awg
From from standard zip cord to high end stupid expensive.
It's near impossible to tell the differences from one to the other based on just memory and time it takes to switch between different cables.
So, I started recording short clips between them.
Listening back to the cips I could definitely hear a difference but it wasn't extreme.
I started reading high fi audio forums and decided to try Belden 9497 after quite a few positive reviews.
To my ears, the Beldon sounded the best (even though it was only 16 awg)
Better detailed mids and high end clarity.
I went ahead and re-wired all my cabs with it, and have been completely satisfied.
