    It has output buffer caps already but I don't know if they are load tolerant?

    This is what cary say about Buffering:

    The audio output section, responsible for providing the actual musical signals, is based on proven Cary Audio designs for the best sound quality. The DAC-100 audio output uses high speed monolith buffers operated with non-global feedback to ensure optimum sound quality. The DAC-100t audio section consists of two (2) 6922 tubes operated in a non-global feedback configuration. In both cases, the audio section is fed with its own discreet low noise power supply.
    Once the digital bitstream is managed it is sent to the digital to analog conversion section, comprised of two (2) ESS Sabre ES9023 24/192 DAC chipsets. These circuits accurately recreate the analog musical signals and send them to the buffered solid state (DAC-100) or vacuum tube (DAC-100t) analog output stages, and then out to the gold-plated RCA or XLR balanced outputs. All of these processes are designed to have no compromises in sound quality, and provide the very best musical reproduction in its price class.
    The DAC-100 and DAC-100t provides a buffered hi-performance line level audio section in either solid-state (DAC-100) or tube (DAC-100t). The DAC-100 uses four high speed monolithic non-feedback buffers and the DAC-100t uses two (2) 6922 premium tubes in non-feedback buffer. You can choose either RCA or balanced XLR via the jacks on the rear panel. Using shielded, high-quality interconnect cable is important to reduce the possibility of hum or interference.
    Some settings may need to be adjusted depending on many factors. A common one is adjusting the buffering for playback. Many times, setting the buffer to on or max can result in better performance. If you hear a ticking or missing parts of the music, you may have to select a feature of your media player to flush the device buffer on startup and so on.

Some cable is easier to work with than others.
    ...would the braided screen need to be grounded/earthed?

    I've not seen any caps earthed this way on thousands of photos! Only basic short circuit screening.

    Should I choose to do this, I personally would put thin teflon sleeving on the capacitor wires and then screen with copper foil or braid. At least that can have wires soldered to it for earthing connections.

    Desoldering braid is thin, made of copper and often tubular. I have some that would be ideal as a narrow screening braid.

    ...do you have a pic please?
    cheers!
