This audio interface continues to impress me. Not only does it faithfully and uneventfully record pristine audio for me every time, it employs state of the art a/d converters that professional engineers can not tell apart from a $3,000 Rosetta converter. Listen for yourself. This thread is worth reading. And if you own an RME Fireface, you will be smiling ear to ear.
