I drove my 3.3Rs with Adcom 555IIs and Parasound 1200II THX
amps. The Parasounds sounded better to me.
If I had your options I'd try bi-amping with the 5802 driving the ribbon & midrange, the 565 monos on the bass panels. The 5802 is a MOSFET amp, it's smooth on the highs but weaker in the bass than the 565s.
You have the option of attenuating the Magnepan ribbon, with a resistor, if the 5802 is too hot (loud) on the ribbon.
