I was excited, waited 6 months to get one. I had bought the new M23 amp last year and was (am) very impressed with it, so I ordered an M66. I liked the M23 better than a new series Bryston amp in my system. The M66 does a lot of cool things. The DIRAC software really makes a difference integrating subwoofers and main speakers and taming the room. Its internal DAC sounds good too. Early models have some bugs in them but NAD is working on those. I’m still evaluating overall sound quality though.
