Maybe this is the right section.

These are the amplifiers:
NAD 315/325
Marantz PM4001/PM6002
Cambridge Audio 340A/540A

These are the speakers:
Tannoy Fusion 2
Monitor Audio BR2

I must choose a good amplifier that will works well with any of these two speakers, any advice?

P.S.: 325 is a bit off since it's price is a bit high.
