Reply to Audio Interface Question

Hello.

I have a Traktor S4 but the built-in soundcard is not Windows compatible (latency issues and yes I've tried all the tweaks), that is why I'm looking at an external sound card or audio interface (same thing?).

What do you recommend and advise?

I've heard the Maya 44 USB isn't that great, and there is a Native Instruments thing for basically the same price but I'm worried it is the same as the S4's built-in soundcard.
What else is there?

Thanks!
