There are volumes (books .. not sound level  ) writen on human hearing and perception of 'loudness'. I'm not going into it here - no expert so I'd get it wrong.. but two tones sound louder if they are close togther frequency wise.
The stebel takes something like 20 Amps .. there is no way I'd rely on the DR650 original wiring/switches to take that current.
