A/V receiver and Legacy Focus SE speakers

I am going to up grade my Home theater, I have been using a Yamaha A/V for a very long time with Klipsch speakers….so wondering if anyone has been using Legacy Focus  speakers, will they be good non-fatiguing for two channel music…manufacture recommends over 30 watts so more then that would be better…

Is there a A/V with enough power for the Legacy in the main channel without a external amplifier?
