I learned something new today
For years I was under the impression that the digital outputs from a CD player would not work simultaneously with the analog outputs. At least that was the case with an Sony I had a few years back. Today I tried it with an Integra DVD player and was able to pass audio to two amps, one via optical and the other through RCA cables at the same time. Maybe I'm late to the party but I'm stoked to find this out.
This will positively impact my use of multiple amps sharing a single CDP to drive multiple speaker arrays.
