OUTLAW RR2150 vs NAD C 326BEE sonic differences?

I own an NAD C 326BEE with a pair of Sound Dynamic 300ti speakers which sounds pretty darn good but the NAD has no phono. I wonder if the OUTLAW RR2150 would be a step up in sound quality. I do not want to spend the money just for the phono option and take a sideways step in sound.

Has anyone compared these two amps? Even a comparison with a NAD 320 or 325 would be helpful.

If anything I would be looking for more high end 'open' quality and/or inner detail.

thanks for any info / tips

Phil
