Help: good value amp for Epos M12.2s?

I'm just putting a system together, mostly from Audiogon purchases. I now have a great sounding pair of Epos M12.2s (up on stands), a Music Hall MMF-5 turntable.

I'm looking for an amplifier (and a CD player) that would go well with these. I listen to a fairly even mix of blues/jazz/electronica/soul, appreciate detail and body in sound. I'm more concerned with lower-volume listening than cranking it up loud.

I know that the Creek 53050SE is hailed as the Epos perfect match, but I simply cannot afford the $900-1,000 that these go for used.

These are the speaker specs:
Power Handling 120 Watt Max
Frequency Response 58 Hz - 20 kHz
Impedance 8 Ohm nominal
Sensitivity 87dB/1W/1m
Amplifier Compatibility 50 - 150 Watt

I have the opportunity to pick up a Cambridge Audio 540A for a very good price. It's rated 50W into 8ohms.

Is this going to be "enough" of an amplifier to appreciate what the speakers are capable of? Or should I hold out for the 65W 640A? Or, should I try to keep my eyes out for a used Creek 4330? Or, save up my pennies and get a Creek A50i, which is also rated at 50W? Any other suggestions?

Thanks a lot!
