Streaming music sound quality

I was completely surprised at how small the MSB separate DAC, preamp and streamer modules are. I could not tell if all their DACs require a separate power supply or if some of them have it built in.

But wow, the system I heard them in had McIntosh MC451 dual mono amps, Sonus Faber Lilium speakers and the top of the line MSB streamer, preamp and DAC.  Wow again.

If you ever near Nashua, NH, drop into Fidelis Audio for a treat. Absolutely no pressure and Marc is great.

I have the Zenmini mk3 connected to the Denefrips Pontus dac. Read the Pontus reviews. I have no complaints what so ever. 

Is there any analog input(s) in your Astell & Kern DAP? If not, I don't see how you can use the DAC on the Zen Mini at all.

Thank you everyone.

DAP OR streamer?
