I’m running N200 with PS Audio DSD MkI now. Bricasti M3 was the DAC I had prior to the PS Audio. Both DACs preformed extremely well with the N200. I’m using AQ Diamond USB cable.
I haven’t heard the DSD MkII but the sound of the MkI is natural, resolving and not analytical at all. Relaxed and laid back. Great texture in the bass. I’m assuming the MkII retains the house sound and improves on everything at the same time. I’ve not heard the T+A DAC 200 so I can’t say if you will like it or not. But I’m 100% sure either of the DACs will be a step up from the in built module.
