From what I have read over there at the other forum, it is not so much the convertors, that define everything you may hear, it is the rest of it. Cheaper convertors in cheaper soundcards, use the program (programmers) that come with the chip, and you get what you get and they (the audio/interface manufacturers) do not change that. Thus you get drop-outs, jitters, other things that do not help the sound at all. With RME, you get their program which they put into the chip and thus the USB, and jitters, and anything else, is the lowest you can get plus they can upgrade their chips they use with their programming anytime they want to make the firmware and drivers even better and even add things that other manufacturers can not do, since the program they are using came with the chip they are using. That is why it all works better in the end with RME. But it is there on the forum and with reviews and anything else over there including explanations of it all.
