MOTU Traveler RME Fireface 800
I sold my FF800 after buying an M-Audio Ozonic controler. It sounded about the same and the drivers behaved better.
The RME driver release policy, that some regards as outstanding, is pure madness... on almost an weekly basis there is a new set of drivers or firmware. Beta as beta can get.
The finest sounding FW card i tested til this very day is the Onyx 400f. It has the same AD\DA of the FF400 but it over samples at 128 bit instead of of 40bit. Its drivers however scared me away. I had my share with RME already.
The Onyx pre amps are just sweet, I can´t find words to do justice to its DI: forget about your plugin folder, sit back, relax and enjoy what has been recorded instead of searching for plugs to mask the short comings of not so good I\O.
The Traveler is not comparable to a 828. period.
There are more reviews. Isaw one on Computer Mag where there was a shoot out between FF800 And the Traveler. Both scored 10\10 IIRC.
The Traveler however got two awards on top, editor choice and best buy.
I´m eager to try the new YAMAHA n series too. They know a thing or two about audio interfaces
