It would probably easier to audition the same brands. It gets complicated very quickly auditioning all sorts of combinations.
I assume you have some kind of connector in there now. Probably just cheap. Good.
I highly recommend you listen for many many hours to make sure you understand what your system sounds like. Personally I use DHLabs interconnects as my standard “starting point”. I make sure everything is broken in and settled. Then start thinking about what cables would be good. I have fifty years of experience and know what the major companies sounds like. Audio Quest, Transparent, and WireWorld and Cardas, and a bunch more.
But I recommend getting at least three sets that are at the upper end of your budget and try them. Dealer or lending library… or friends. Take your time… like listen for a day each and switch. The improvement must justify cost.
