Mismatched Preamp/Amp Impedance--What Will I Hear?

I've got a Ming Da (Meixing) MC-7R tube preamp sitting in a closet. I got a good deal a few years ago and it uses common tubes that I have a lot of, so I bought it. However, I never used it much because it didn't sound as good as my main tube preamp.

Anyway, I'm thinking of taking it out of storage and at least playing with it. Its output impedance is 100K ohms! All of my solid state power amps have input impedance between 25K and 50K ohms. Cable length between the two will be one meter.

What will I hear (or not hear) as a result of the super high output impedance of this preamp. My main preamp easily satisfies the 1 to 10 rule, but the MC-7R doesn't come even close.

Thanks for any insights.

Thanks for the responses. Hope you're right about a translation error. I found the 100K output impedance in different places on the Web, but perhaps they all result from the same translation error.

I just try it out and see what it sounds like. My other tube preamp has 400 ohms output impedance so it should serve as a good comparison.

There is no way it is anywhere near 100K as stated. If the preamp is tranny-coupled it could be as low as <100R. If not and has a cathode follower then ~1000R. If neither could be as high as 2-3K ohms - that is about the upper-limit.
