Hi, as distributor for RME it's probably not really our place to do sonic comparisons with other brands. Then you have the fact that even for 4K videos, AFAIK RU-vid applies a fairly liberal amount of compression, raising the question of how beneficial a comparison on RU-vid really is (especially for devices where sonic differences tend to be fairly subtle). I'd recommend checking out the following Sonicstate review for an excellent discussion of RME sound quality; RME Babyface Pro FS and Fireface UFX+ Review - Sonic LAB ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-xySFqxQSz7k.html
