I am a new owner of a K22, which I am just beginning to get used to. My question is whether there is any solid technical rationale to using a DDC between the K22 and my DAC. I am not a technical expert by any means, but I have read through the design section of this website, and it appears that using the K22 in front of my DAC will make any DDC redundant. From my limited understanding DDCs are useful in cleaning up the USB audio signal from computer-based systems, but it seems to me that any necessary ‘cleaning up’ of the streamed signal is now being done by the K22.
Is this a reasonable summary? I don’t mind investing money in a DDC if it provides some sort of tangible benefit in audio quality, but equally I don’t want another box in my system if it really won’t add anything.
