I also think the Lynx is not a bad unit call your dealer.
But if you want to change many classical engineers in Germany use stuff by RME.
My opinion is that their converters are good and clean and do not color anything. RME: Fireface 800
For sure you can pay a lot of cash for better conversion but I think RME and Lynx are playing in the same ballpark. And with my RME I never had trouble except one accident caused by my flat mate.
Beside from this since 4 years running here without any trouble stable drivers fast support within one working day... great company. They know what professionals want.
Just a suggestion.
