What confuses this luddite is that there is already volume from the MP3 player and yet more volume is needed from the stereo.Shouldn't it go thru the same amplifier circuit as the CD and radio?

It's not the cable that will 'draw all the power' but essentially, because of the mismatched impedance of the Sony's output to the stereo's input, the stereo will only receive a small fraction of the required signal to drive it. Hence you have to turn the stereo's volume way up.
Think of it like trying to power something that wants a 9 volt power supply input with only a 1.5 volt AA battery.
The only way to change the situation is to either change the mp3 player or the stereo. A new mp3 player will probably be cheaper, sorry to say, and you already know what brands will work!
