BluRay from Oppo into Kisto

Some here decode BluRay sound formats on their oppo 105 and feed the analogue outs (blacks or silvers?) into their Kisto.

Surely the Kisto has vastly better DACs. Also I've only a 83se currently.

Is it really worth doing this? Surely a slightly lower res format converted by the Kisto would give much better results.

Thanks for your experience and wisdom.
