I've got 1.1V sensitivity@22k ohm
I take that to be the amp's specs, right? I.e. it reaches its peak when fed (a max) of 1,1V & its input impedance is 20kOhm. That's not too bad...
But are you saying your players have an "output impedance" of 10kOhm??? That's too high... I must have misunderstood something.
OTOH, 2V output is more than enough to drive the amp -- and then some. You should be able to use a passive attenuator on it.
(BTW, it's called "impedance" when the "resisting" factor changes with frequency; it's called resistance, when the "resisting" factor remians constant whatever the frequency)
