Thanks Forum. Some suggestions I hadn't considered. Didn't realize that with 5.1 surround, the center channel was doing all the work. Buying a set of smallish L/R mains is a potential solution. Also like the aux input to Rogue amp using analog outs. Creative, even if not perfect.
For gillatgh, I bought a switch from Amazon (Specialty-AV SP-71). Generally a well built unit with double rocker switches (L and R) with banana plugs and 16 ga internal wiring. My primary concern is that there is a 5W100 ohm J resister across each of the four amp inputs and I'm not certain what effect on sound might occur introducing this into the signal path. We place significant emphasis on speaker cables etc, only to insert a switch....I'm having second thoughts.
Can anyone comment on the true audible effects from placing a resister across amp outputs as a protective measure?
