Looking to bring the rest of system into this century by adding a Pass amp (XA160?). All source equipment is AR--LS27, DAC8 and PH8. Realize that there many variables, but does anyone have any thoughts about this combo?
what's the rule of thumb of pre output impedance to power amp input impedance ? That should better address the OP's original query.

I thought the input impedance of the amp had to be at least 100x that of the output impedance of the pre?
I see the Pass XS series, the pre has an output of 20 ohms and the amp has an input of 200k !!
