Its character that you need to match up really. Watts etc are not very important so long as you have enough power to get a decent volume without having to turn the dial on the amp to 10! Looking at the amp you have I see from reviews it is 50watts so that is more than adequate for the Epos speakers. It is also smooth with a sweet treble so again, that will suit the Epos's well as they don't like an unruly treble - indeed they do well with Rega amps which are sonically similar in description to the Marantz.
The Epos look even better in the flesh btw
It's better to have a twitchy front end than an itchy front end!
