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.

Arni, please forgive me. I made a huge error in my previous post. It should have read as: "the Rotel's input impedance does *NOT* make for a classic candidate for a passive pre."
I think Symphony Sound is right. Working and optimizing are birds of a different feather. Arni, the Rotel's input impedance does make for a classic candidate for a passive pre. Not knowing the source specs or cableing prohibits a defintive answer. The fact that it will be driving a sub amp as well, doesn't bode well.
