RME Fireface UFX In original box (also have the Octamic XTC for sale). This unit is fantastic and has been a staple of my professional recording studio. I once tried to change to Universal Audio X8P but still had to keep this racked because sometimes the Apollo didn't want to work and when you have clients you need something reliable. This is it and has a great user friendly mix console too.
