is a 555:1 impedance ratio ok?


my amp has an input impedance of 75K ohms, and the pre i'm thinking of purchasing has an output impedance of 135 ohms. Is this ok? the amp is SS and the pre is tube.
thanks

I dont have the specs but i can call thiel tomorrow... unless someone else has them.

so do i need to match the preamp to the eq box? i wonder what a desireable pre/EQ box ratio is.
i hava a classe ca-200 and am thinking of getting an anthem PRE1L.

something else i've been wondering about... i'm using thiel 3.5s that come with a bass EQ box that goes between the pre and power amps. what effect, if any, would this have on impedance matching? does this complicate matters?
i'm not sure if this posted correctly before, so forgive me if this is a double.

does the output impedance of the EQ box change if i switch between two different preamps with different output impedances?

i think i need clarification on the relationships between input/output impedances when components are connected in chains.
