thank you for your fast support. An mp3 file is perhaps not the best format for it, but you can hear in it exactly the noise, which I also hear on headphones! Therefore, I find the file is not completely wrong. If the Zoom UAC2 is generally known to have a slight noise floor, why is not it heard on all sound files? Many samples in the SD3 sound crystal clear and mega perfect. I have the noise of many standard presets in the SD3, this is not due to my own presets!
The Zoom UAC 2 can not reproduce certain Hz areas properly? My high quality headphone reveals these problems.
I will test RME Babyface Pro, when I have the same problems, I´m a sad boy 🙂
