NAD M10 Streaming Amplifier DAC

I bought this recently to try in my second system. It’s really impressive with the Bowers & Wilkins PM1’s in my living room. I didn’t try the Dirac room correction because I didn’t have time and I wasn’t sure that the speakers could get much better. I found this compared favorably to the Naim Unity Atom. The Naim had a more detailed soundstage but less grip on my speakers. I also prefer the user interface of the M10. Also, this unit has nice binding posts while the Naim requires banana connections.   
This unit comes with the original box, manuals, power cord, and Dirac room correction microphone.
