Using 2 different brands of interconnects?

No. More than 2.
Doug advises against it so what do I know?

you'll get changes from one on vs slightly different changes form the other. it may all be complimentary as total stack of effects and considerations, or it may not be all complimentary.

No harm will be done and it certainly won't stop the tunes from flowing.

And there's not much else to say about it... try it and see kinda thing.

Good? bad? You're the guy with the cable...

no cables were harmed in the making of this comment.

OK, thanks. I’m done if y’all are done.

It's not a problem, especially in your price range, unless you're talking about about mixing within the pair, e.g.: Brand X for the right channel, Brand Z for the left.

There are no problems with using different interconnects on different pieces of gear at all in act in most cases t is preferable.
