I bought the 802 FS AE to extend my 5.1 setup via ADAT, since I’m already using the same unit for my analog gear. Having two of these working together is honestly a dream and they sync perfectly, the ADAT functionality is flawless, and the converters sound fantastic. The drivers are, as always with RME, absolutely rock solid.
I’ve been using RME hardware for 20 years and I wouldn’t consider anything else. This is simply top-tier, reliable, professional gear.
