The Sonus Faber Auditor M Speakers are, in my opinion, excellent speakers. I own the Ayre AX-7e Integrated and like it very much with the SF Auditor M Speakers. I am using a MAC Book Pro computer connected to the Ayre QB-9 USB DAC. I am not familiar with the Naim or Dynaudio.
The MAC USB output is connected to my Ayre QB-9 USB DAC. Wow! I was very impressed with the way it sounds. It is better sounding than my Ayre CX-7e CD player. The highs are better and so is the bass. The music is clearer and more engaging.
The Ayre AX-7e Integrated and the Ayre CX-7e MP CD Player is also a great combination. The MP model is their new model. This combo sound best if you use balanced cables (XLR).
