    That caused distortion whenever I had just the DAC and H/phone amp on, everything else off. I never tried turning on the C31 at the same time
    Powering up the C31 should be enough to cure the distortion.

    Yes, no need to switch the P1s on as well.

    The OP just has to try it and report back to us.

    It was probably just a slip of the tongue/brain/keyboard and what he meant was the exact opposite of what came out.

    Yep, that also works (C31 on without power amps on too). Still don't like the idea of having the pre on for no real reason when using headphones so will be using the Tisbury and going through the loop output on that, at least for the time being.

    Just want to thank all those that replied and helped me to understand the situation, especially Andrew.
