But doesn't the headphone jack on the Marantz still have reduced power output compared to the speaker output - also, if true, by how much. I understand that the planar drivers are purely resistive without a reactance component, so not having to worry about impedance matching. Am I missing something here?
Also, if I do decide, how I would I go about connecting to the binding post of the Marantz? I already have banana plugs to female XLR adapter that I use to connect my balanced headphone cables into. Although these Marantz units didn't support banana plugs. How would I go about using my current setup with the Marantz. I really don't want to invest in hard wired cables of the Marantz. Would a further banana plugs to pin adapter work with the Marantz post?
