Now you spread misinformation ;). Is there any scientific source for

- < 48 KHz sound can be ok for some sources, but it
also can become very bad

but if you compare that gear with other gear at 48 KHz
it doesn't sound better
I don't have experiences with conversion from 48 KHz to 44.1 KHz, when I
did it (doing something a few times doesn't lead to experience), the
sound becomes less good, that's the nature of 44.1 KHz. I don't know any
scientific reason that a conversion should cause issues, but producing
at 44.1 KHz does cause issues, since the sound is less good, mixing is
harder to do.
I was asked how the sound quality is, when I use 192 KHz with the RME
card, but I can't answer this question, because I don't record at 192
I guess the bit depth is important, especially for production, perhaps
less important for listening to the finished recoding.
