Jerome...I am surprised by the drop in power output. Usually, tube amps output the same power into different loads. With SS amps, the power output typically increased into lower loads (well designed SS amps usually double the output as the load increases by 2x, so going from 16ohm load to 8ohm or from 8ohm to 4ohm load is a doubling of the load at each step - as you go down, the load increases). So the Shindo CCQ is 70wpc into an 8ohm load but drops down to 17wpc into 4ohm load, that is very interesting.
