Passive preamps and poweramp's input impeadance


I have a Rotel poweramp with 33khoms input impeadance, and thinking about driving it with a Creek OBH-14, which is a passive preamp/DAC combination. I have been advised that the Rotel's input impeadance may be too low..
How would this affect the sound etc..., and would it be a bad idea? (I'm unable to test before buying). The Creek would also be driving a NHT SA-2 sub amp.. which I do not know the input impeadance for.
Your comments would be greatly appreciated.

Well maybe Nelson pass says it's ok but I sure as hell wouldn't run a 10k ohm preamp into a 23k ohm amp. Just my two cents worth. Sure it'll work - but it's not going to sound as good as if the impedance were matched better.
