thks- It seemed odd to me to run from output of dac to amps but here it is from page 24 of manual unless I am reading it wrong-
"The diagram above illustrates the use of the digital output of the PreMATE or PreMATE+. Connect the digital output, labeled Full L2/R2, to an external DAC via a BNC cable (or an RCA cable with a BNC-RCA adapter). The outputs of the DAC are connected to the power amplifier, which in turn drives the left and right speakers. Note that the external DAC must be capable of decoding a 24-bit 96 kHz signal "
