Isn't two pairs of RCA jacks on the back panel equivalent to Broskie's output selector switch? If one were to use the switch, the non-used caps output is also just dangling there...............
I agree, given the low source impedance of the aikido output this should not cause any problem at all.
Not sure what sort of problem tinitus had with his speaker level x-o..
FWIW I do agree that limiting the quantity of switch contacts in the signal path is advisable. (Very high quality switches do help)
YMMV..
