10K ohm input impedance on the Gryphon amps according to specs is not a great # for use with tube pre-amps, which tend to have higher output impedance than SS amps in general.
The Wavac advertises 600 ohm output impedance, which is a nominal estimate and can vary at different frequencies.
Of course specs are just guidelines. If you hear any problems with clarity or loose, messy and not clean clear and dynamic sound, this matching might be something to look more closely at also.
