NAD classic power amps good, great or mediocre

Hello
I wondering if the current NAD power amps (classic series)
can stand up and give out with really good pre-amplification??

I've read a few places where people use these to very good result with pre's that are in a different class than NAD's own.

Comments welcome.

I'm looking for some good ss amplification like what an Accuphase P-300 might bring,I like that kind of sound.

Thanks!
