I agree with others who stated that JM Focal speakers can use the harmonics from tube amps. I have another SS power amp, rated at 200Wpc/8ohms and 400Wpc/4ohms, and my Alto Utopias sound a bit dry with it.
So I ended up with a completely redone Counterpoint NP100 power amp that is rated at 100Wpc/8ohms and 200Wpc/4ohms. It is a hybrid amp with tube gain stage and SS output stage. Mike Elliott voiced it like SET amp sonic signature. (Yes, its upper mid-range does sound like my 300B SET amp.)
200Wpc/4ohms may sound like a lot of power. But when I play Beethoven Symphony No. 9, it is barely enough towards the end. I can't imagine if it only had 50Wpc......
