HDDG 10-14-2016The Coincident Statement Line Stage has transformer coupled outputs, and no capacitors in the signal path. Therefore it will avoid the large rise in output impedance at deep bass frequencies that occurs in most tube preamps due to the use of a coupling capacitor at their outputs, which can result in the deep bass rolloff Dover referred to earlier if power amp input impedance is low.
My preamp output impedance is 500 ohms, would an amp input of 10K ohms be fine??
However it is conceivable to me that other adverse sonic effects might occur, at least to a slight degree, if the CSLS is loaded with a low impedance such as the 10K input impedance of the Gryphon Mephisto Solo. So I would suggest contacting Mr. Blume of Coincident and asking what minimum load impedance he would recommend for use with the CSLS.
Good luck. Regards,
