I purchased this after using a Behringer U-phoria 404HD for the past 3 years. The preamps and DI when used with my Lewitt mic and electric guitar are leaps and bounds above the 404. Clean, full-bodied, excellent transients and low noise floor, and great harmonics. Recorded audio sits well in the mix without much processing so this could easily be used to make commercial tracks. The dynamic range of the DAC is amazing and really makes untamed transients much more apparent.I have 2 sets of monitors, and A/B-ing and mono-ing them with the press of a button makes my life so much easier. I have not had any problems with the drivers running on Windows 10.
I know from checking forums that people have complained about stability with their past drivers, but the new version 4 has been rock solid.
iD44's connectively is insane for the ₹'s and the box feels reassuringly solid so I expect to grow into all the features of the interface.
Initial impressions are outstanding.
