How strong is the NAD M15 2 channel performance?

To those who have owned and/or used the M15 (non HD version), I have a couple questions. How good of a 2 channel preamp is it? How good is the DAC section?

Is it on par with something like the Adcom GFP-750 or a Parasound P3? I've considered the Monarchy NM24 with a Placette RVC (I need a remote), but that is just beyond my budget at this point.

I'm using a Coda 10 amp. Any suggestions of a preamp that pairs well with the Coda? Your thoughts and opinions are appreciated.

Thanks,
