Impedance matching between 2k ohm phono pre and 100k ohm amps via passive pre

tubed phono stage (2k ohms output) through a passive preamp into two Dayens Ampino mono blocks (100k ohms input).  

With the phono stage output impedance being high at 2kohms, I would search for a passive that uses a 20kohm volume control (potentiometer) not 10kohms one.
As it will still be a better match, and also still be a good match for the 100kohm of the poweramps.

The low impedance is on the drive side so that is not a concern.

The output impedance of the source is 2kohm, so the load it should be at least a 20kohm passive. The the output of the passive will be fine with the 100kohm input of the poweramp.

Ah ok - that makes sense.  Noob that I am, it did not occur to me that passive pre's have in and out impedance.  

Seems I'll either have to change pre-amps or the phono pre.  Maybe.  I have a Schiit Valhalla 2 that I can try too, but there's no spec on input impedance.

If I'm putting 2k ohm into a passive pre with an input impedance rated at 10k ohm, it means I'm not going to get 100% of the bandwidth? Signal?
