But with N200, you may not hear any difference vs going direct. Just ask @soix what streamer being used before DDC.
That’s why I asked which input is best on the Gustard because everything depends on that. If Gustard says their i2S input is superior then you’re probably looking at a nice improvement with a DDC and i2S versus going direct even if you’ve got the Aurender, but if USB is equally as good then absolutely going direct from Aurender, etc. may be perfectly fine. I’m using an iFi Zen Stream, but in this case it really comes down to which input on the Gustard is superior, and I’m sure they can tell you that. My point was that IF the i2S input is better on your DAC as it is on mine, then an extra $400 or so is like a DAC upgrade on the cheap that can work in concert with the better streamer.
