It is the pre-amps output impedance that is important relative to the amps input impedance. Considering you amps 50K input impedance, if the pre-amps output impedance is less than 1000 it should be OK. Less is good. If it is 3500 or more it could be a problem. Could be, but it might be OK.
Amp/pre compatability
Have a pre with 50kohm input impedence, and thinking of pairing with amp that is rated at 15kohm input impedence. Don't know enough about this issue to figure out if this would work. Any help appreciated.
