Our tube preamps don't have an output coupling cap- so they can drive 600 ohms let along 10,000 ohms with ease. The output impedance is the same at 5Hz as it is at 1KHz or 30KHz.
Generally speaking though, most tube preamps are likely not to play bass right driving 10K, simply because of the output coupling cap being too small.
