Hello people, I comment my doubt. I have a Technics SA-EX320 (quite old) synthesizer that supposedly rolls 80 + 80, in other pages they say it rolls 40 + 40, and in other 70 + 70, but suppose it rolls 80 + 80. Now I want to buy an ampli that rolls 100 + 100, the question is .. Will there be a difference in power? (would it sound louder, so to speak) the 100w compared to the 80w? They are 20w apart (assuming the Technics rolls 80 + 80, if anyone knows how much it throws, please tell me) and I want to know if those 20w are noticeable .. I await your answers friends, thank you very much!
