I have a used NAD M32 on order that should be here mid/late next week. I've read good things about NAD's newer class D amps and will try and remember to post my thoughts here. I can also vouch for the PS Audio M700s. I would describe them as balanced and neutral (in a good way) more than warm and syrupy (to continue using the term, lol). However, they are fairly smooth, grain-free, and lacking edge. I would have to agree with the comments that 1) you probably won't get "warm" with a class D (at least under 2k?) - at best you'll get smooth, and 2) it would probably be best to add warmth with a tube pre. Happy hunting!
