Whether it's 10k or 50k won't change the slope. That is an independent parameter.
The output impedance of a 10k pot is lower than 10k so the impedance ratio is better than 4.7:1. If you are worried by the ratio, or need long cables between the preamp and power amp, then get an active preamp not a passive attenuator.
