Naturally, I’m looking for the same brand for all three.
Naturally? Why? I could see this being the case only for buying more of one already known to be good and what you like. To buy three unknown all at once seems a good way only of tripling risk.
Even though you know you love your Zavfino speaker cables that is no guarantee you will love their interconnects. I always take components one thing at a time.
Seems to be a trend now to have LOOMS.
All wires and cables in one brand.
I do this because I am OCD.
