ODAC performs best under a single load. To achieve published performance, we strongly discourage paralleled loads to ODAC. Properly customized assemblies allow ODAC to be disconnected from O2 when driving an external line-level device.
You can find connectivity advice in the JDS Labs O2+ODAC instructions.
Thanks for the heads up, John!
I'm not noticing any sonic degradation with the way I have it wired, though.
Wouldn't putting a switch in front, as I have, effectively qualify as a single load depending on the switch position? Or does this still count as a parallel load?
