The only way you're really going to know for sure is to put them through a battery of tests yourself and see if you notice any difference. Someone could come along and post that they like one better than the other but you might find that you like the opposite better.

🤣 yeah that's true but there could also be some hardware stuff I am not aware yet 😀

Like sliderider said! Test both cards and use the one that is less noisy 😀

Either that or simply pick the lower one as it seems to be a newer release. Personally i never heard differences between modern sound cards, but if you can hear extremely well then just try it out. Personally I'd be surprised if you can hear a difference.

Maybe one is less noisy than the the other? That would be what I would check out. Creative ISA cards can vary a lot in that way from revision to revision.

Since noise is the main factor here I'll check them and report my findings 😀
thanks for the suggestions!
