First Foray into XLR

I know this is a topic like ‘oil’ or ‘tires’ on a car forum, but I have to ask...

Marantz AV8802a to Odyssey Stratos amp to Aerial 7T’s. Looking for advice on 1M XLR’s from pre/pro to power amp.

I’m skeptical of cables and snake oil claims, but I’m trying to be open minded. I’ve not used XLR before, so I’m not replacing anything, and not looking to spend a fortune, but would like input from others who’ve been where I am.

thanks
