USB headphone amp for around $100?

[GlenicoNico]

I'm looking for a usb headphone amp. I don't have a budget to be honest. I just want to get the best for my money without being too expensive. Under $200 would be nice. Help?

My headphones are 80ohms.

Any answer will be appreciated.

Overpriced and overhyped(if it were at it's original price tag) but I'll throw this suggestion for an Astro MixAmp Pro in here that's setting up back just above 100USD though you could take a look at these:

Based off of the data sheet for the uDAC3, that would be up my alley!
