Metrum Octave and 192khz?

I'm considering buying the Metrum Octave even though it has 2 hurdles for me (1) no volume control for direct to amp (2) no stated support for 192khz. I can probably live with out the volume control. Comments online look like folks have had both success and failures using the Octave for 192Khz. So consider this an informal poll for any willing Metrum Octave owners to help me and other fellow audiogon members considering the Octave to understand how likely 192khz would be to work or if a particular input device improves the chance it will work

1) are you able to get 192khz sync reliably with your Metrum Octave (yes/no)?
2) what input device(s) are you using when you try to sync 192khz with your Metrum Octave?

any shared user experience here deeply appreciated
