NAD C372 Integrated or Bel Canto s300i Integrated

I am interested in the following two integrated amplifiers:

NAD C372 Integrated Amplifier
Bel Canto e.One S300i integrated amplifier

Any thoughts on these two units? Budget is $1000 to $2000. Here is some info about what I am interested in-

1 Enough power for a medium size room- with no amp strain
2 LOW NOISE unit
3 Good tonal balance and a can produce low, mid and high frequencies without bloom, harshness and with smooth midrange.
4 Neutral in presentation of the music (not warm or otherwise adding it’s own sonic signature)
5 Wide soundstage
6 Dynamics, microdynamics and quick transient response
7 Great detail
8 Musical

I will be using a Benchmark DAC with an optical switch between a Rega Apollo as a transport or
Itunes library played through a Slimdevices Squeezebox. Speakers will be 4ohm floorstanders or 6ohm bookshelf of average sensitivity.

I can also use my Benchmark as a preamp, if anyone has any OTHER suggestions for an integrated OR stand alone power amplifier.
