Topping vs Dac audiophile

[zaurux]

J'aime bien cette réponse de l’administrateur du Forum de la marque RME, sur les différents filtres de décodage et la différence entre le monde "Pro" (celui qui créée le support) et le monde HiFi (celui qui écoute le support).

La question de départ :
"..by the way, why RME calls super-slow filter of 4490 as NOS ? Actually NOS-DAC's are differrent story."

Explained in the manual. Seeing the stairsteps and the massive aliasing effects it is bad enough to be called that (the reason that we made it available at all is that the oversampling is reduced, but not completely gone. Therefore the filtering is still there, weaker than with Delta-Sigma, but more than real NOS. It's an interesting approach, and the side-effects are tolerable in certain applications).

But the point is: the Pro is a Pro tool. Calling a filter 'SuperSlow' has no meaning for anyone. Imagine someone transfers precious recordings through an analog chain, uses the Pro (or DAC) as DAC, processes it, records it again at Hi-Res. Then a year later the engineer discovers that all transfers are completely messed up with high frequency noise, aliasing, and even the expected response in the higher treble lacks. Then that guy is fired and our reputation completely destroyed.

In HiFi people can do to the music whatever they like, it's their fun and usual has no serious consequences, right there at the end of the chain. In a studio environment R2R and NOS are an absolute no-go. So is 'SuperSlow'.
