Is there any scientific source for that claim? My impression is (might be scientifically right or wrong, it's my experience) that - < 48 KHz sound can be ok for some sources, but it also can become very bad - > 48 KHz you don't hear an improvement, IOW 48 KHz is all that's needed - There is some gear that does sound better at > 48 KHz, 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 Khz. I guess the bit depth is important, especially for production, perhaps less important for listening to the finished recoding. YMMV!
