NAD 2150 vs. Onkyo M-282

I am looking into buying my first power amp, I narrowed my choices to an ONKYO M-282 ($209 refurb) or the NAD 2150 ($149 used) I know ONKYO makes good recievers but not sure about their amps. I am conidering NAD because I hear so many great things about them aspecially if you listen to music (I mostly listen to music) and if I can spend $50 bucks less I will take the NAD. I know the NAD 2150 is old but it's a question reproducing my music as accuratly and clean as the up-to-date ONKYO. Or will it pump more power (unbridged) then the ONKYO. Please if anyone has any commets please fill me in.
