Musical amp/pre/integrated for Maggies 1.6Qr

I just got a pair of Maggies 1.6 with upgraded Cross Over.
Now I am using it with a "better than nothing" NAD C740 receiver.

I am looking for amp that give me a very musical (not hi definition) i.e. tube like amp for probably sub 1.5K used.
I listen to a lot of female vocal music and some Jazz and classical.

I switch from 300B tube SET amp so try to keep the character from the SET on my Maggies. Is it possible to do that?

For the amp, Plimius 8200 integrated comes into my mind.

Any other good amp out there? I know that it's been accepted that Maggies needs lot of power, but I do not listen very lound (less than 100dB.) I wonder if I do really need that much power for the amp. As for now the volume on NAD C740 (35w @ 8 Ohms) never passs the 12 O'clock position yet.

As for class A amp, how much power maggies need? Is 30-50W class A amp good enough for 1.6s?

Thanks a lot,

Ake

PS my CD player right now is CAL IkonII
I also have AES AE-3 tube preamp that could go with power amp, but prefer the whole integrated if possible.
