Perhaps, after this, I will do the same to the 803D3 ;-)

Yes I would support that.

   

Looking at the binding posts of a 803D3 I see your jaw drop when you've exchanged them for banana sleeves and listen to the result. These binding post look massiv - these are of no good.
In case you don't use a bi-wire speaker cable blend the two cables together inside your 803D3 to get only one port for "+" and one port for "-" , because braces between bi-wire binding posts are even worse for sound.
You can do an experiment (if you already use Banana Plugs on your speaker cable) and turn off these big shiny outer Chrome Clamps. Then plug in your bananas and listen again. You will hear the lower amount of eddy currents that are produced by the mass of the outer Chrome Clamps.
