Original Minimax DAC output impedence?

I read on Eastern Electrics website that the DAC has output impedences of 10 k for solid state and 22 k for the tube output! Is this a misprint? I've never heard of any device having anywhere close to that kind of numbers. Any have any idea what it might be?
Got an answer from Morning Star Audio that it is indeed a misprint but he could not remember what the specs actually were other than they were much, much lower than 22k & 10K. If I were to venture a guess I'd say they were 1k and 2.2k. But if anyone knows better please let me know.
