John, thank you for your reply. If I understand you correctly, I would simply install the Adapter on the input of one Amplifier, and then interconnect each Adaptor with the same channel on the other Amplifier? This certainly would be a cleaner set-up, especially for a 2-channel home audio system. Other than high line level impedance, will there be any "degradation" by splitting the signal out of the Pre-Amplifier?
