Speakers are ProAc 2.5...sensitivity is so-so at 86dB. Likely to be replaced at some point.
As far as impedance matching; the AR output is 700/350 ohms (balanced/SE) while the Pass is listed as 30K/20K...I assume the 30K ohm figure is balanced. Based on these specs, the ratio for balanced is...
Don't want to deal with power tubes. That being said, I really haven't given much thought to AR solid state amps. Just starting this upgrade process. The last time I played the game was in the mid-late 90s.
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?
