Can the xDuoo TA-10 drive powered speakers or an amplifier from the RCA outputs--controlled by the volume control?
And is the tube in the circuit of the RCA outputs?
How is the active coax out (with a USB input) supposed to be used? Can you feed an outboard DAC and loop it back to the TA-10 via RCA inputs 1 or 2?
Is a service manual/schematic available?
Thanks.
