Krell 400xi vs NAD M3 vs Music Fidelity A5 vs Naim

Hi,

I am an newbie, but I have been regular reader of the forums. I need to get an integrated amp to use with a SlimDevices Transporter and a pair of NHT Classic 3's,

I would like to choose between the integrated amps that I have been reading good things about.

Krell 400xi
Bryston B-100 SST
NAD M3
Music Fidelity A5
Naim Nait 5i

My musical preference is mostly rock, alternative rock and some classical.

Thanks,
Sunil
