Great quality cable, even for the price. I use this cable for my recording guitar DIs though a Radial Engineering Pro 48. Connectors feel great and the length is just right.
Do gold connectors improve sound quality? Probably not. Most likely by an insignificant amount.
Do they improve SNR? Maybe.
Do they help you sleep better at night, knowing that your cables are top-notch and won't mess up your recordings? Definitely.
