You agree with what I typed above here!
twice the signal = 3db increase
We obviously seem to be talking CROSS purposes.
I realise what you say is correct, But I have always quoted in Electrical
energy, not in Aural effect
in simple terms. Auditioned

There seems to be little point in continuing with this as both points are
