I'm looking at the possibility of using an amp that can deliver 60wpc into 8ohms. By my reckoning that's an output of about 22v. Into a 20 ohm load that would be 24wpc. If I divide that by 10 then it gives me effectively 2.4wpc. If the CDs have a sensitivity of more than 100dB then that should be more than enough. Have I got that right, or am I missing something?

PS. The 60wpc is not the max power output.
