I have been using RME since 2007 in my studio and it has never disappointed me. From 9632 to Fireface 800, Babyface first generation and now Babyface Pro Fs.
Pros: Super stable drivers, no latency, impeccable sound, very clean and detailed recordings! Whenever you write an email to RME, they are prompt and respond immediately. I will always stay with RME!
Cons: Nothing, really nothing!
I recommend to all those who want a transparent, clean sound and clear recordings!
