The good thing about the NAD is that it has good name recognition and is readily re-sold without taking too much of a loss. Generally speaking, though, it is considered to be pretty much an entry level phono pre and not one of the better ones at that.
I'll re-iterate what I said above about the DB Systems phono pre as I think it would better both the Bellari and the Gram Amp, probably for much less money. To put it into perspective someone that I purchased the MM version from for my son's system that owned both the MM and the MC versions of the DB Systems preferred the MC to an older version of the Lehmann Black Cube with upgraded power supply. The Lehmann has generally been very highly thought of, sold new for around $700 and they typically sell instantly on Audiogon in the $300-$400 range.
The only bad thing about the DB Systems is the poor name recognition and limited resale that goes along with it; other than that it's a great phono pre that makes a lot of sense in terms of matching up/balancing well with your existing front end before you upgrade in that area to go really upmarket and then want to do the same with the phono stage.
