Hello all, my first post here, but a long time lurker.Having recently moved into a new house I have replaced my A/V receiver with a Denon X4200w. The Denon is a 7.2 receiver but has 9.2 pre-outs. As I want to move to 5.1.4 Atmos in the future, the logical choice seems to me to take the plunge and buy my first ever power amplifier for my front R500 speakers. Have spent much time reading these and other forums, and have now found great (2nd hand) deals on both the Nait 5i and the Sonneteer Campion. I will not be able to listen to them in combination with my R500's beforehand, however. Thus I am looking for some advice/experiences. Other than which one will sound best, I am concerned with whether the Campion is powerful enough to drive the R500? It's rated at 34W, the Nait is at 60W. My listening space is about 9x5 meters (main living room). Any thoughts and suggestions would be very welcome!
