NAD C165 vs Parasound 2100 vs Emotiva USP-1

I was looking at a pre-amp and wondering if I could get some opinions on the following.

- Emotiva USP-1
- Parasound 2100 new Classic
- Pasasound Halo P3
- NAD C165 BEE
The major problem with the EMOTIVA stuff, from an audiophile point of view, is that it does not cost enough!
if they tripled the price they wouldn't be able to keep them is stock. performance has nothing to do with it.
I have no problem with value priced hardware. My concern is more that I have seem feedback from several sources that the emotiva USP-1 is bright. I only care about the sound quality and build quality.

Any comments on those factors?
