NAD M33 or NAIM UNITI NOVA?

Thank you very much for your answer, I think I am going to decide on Nad. With what speakers did you hear them at the dealer?

I don’t remember the brand, it was a 2 way tower which doesn’t really narrow it down much. I can say with confidence it wasn’t B&W or other distinct looking speaker makers.   I was shopping amps/streamers so wasn’t really paying attention. I told the guy that I had Dynaudio speakers, so he probably chose something with similar characteristics. 

Contour 1.8mk2. I’ve had them for over 20 years now.  I’ve used a bunch of amps over that time frame, but have never thought about changing speakers. I find that vintage Dyn’s have a natural sound that is detailed without being overly analytical, which is a must if you listen to a lot of live music, especially rock from the 60’s and 70’s. The last thing I want to think about is the quality of the recording, especially now that I typically stream everything. 

I am using the Naim Uniti Star with Roon as we speak, I made an offer on a used M33 and fortunately found out that it is another Hegel H390 issue where the Manufacturer stated it was Roon Ready but Roon changed their terms last year and now several devices marketed as working with Roon do not. I have had 2 H390’s and each time tired of waiting for the BS Roon "Readiness" that they were advertised to have. So be aware if you need the Awesomeness that is Roon you will not have it for an Undetermined amount of time from the NAD unit sadly. Yes I am bitter.
