Naim Nait vs. NAD 375BEE: Soundstage

I am considering the Naim Nait and the NAD 375BEE. Both are similarly priced integrated amps with a long pedigree. Which has better spatiality and soundstage? I have Audio Physic Virgo 2's and play a lot of ambient music. I dont need to play at high volume, nor do I need to reproduce dynamics and transients. thanks!!!!
