I take it the Supra has 100+ hours on it? I’ve not used a Supra coax but have their ethernet and power cord and was very impressed with them, especially for the money. If you want to try something cheap that is very good look into the Canare with their crimp end and not another brand as it’s not the same. Had one of these years ago and no idea where I placed it. I have Canare XLR balanced cables currently and they are very good, and again for the money good luck finding something better. I use a Nordost Silver Shadow which are NOS and are reasonably priced. Very happy with the Silver Shadow. I’d suggest try the Canare first as it’s silly affordable.
