My thoughts are that mastering hardware devices/versions are very expensive mainly down to the converters, especially if there purpose is is to add colour.... maybe this would be fine for pre masters and low gain mix glue (not pushed) but I can't imagine the converters are good enough for professional mastering work?! Like the type of job you'd pay for, tho I'd be happy to be proved wrong.... just doesn't seem possible at this price.
That's my perception anyway.
I know cenk mentioned mastering in the vid as well as culture vulture however I can't imagine he meant this would be a replacement for actual mastering hardware like the much more expensive mastering versions of gear which feature very expensive components for a reason (clarity)
I see it as a mix tool only, up to pre master but not pushing the whole mix to mastering levels. Like I said glad to be wrong. x
Can't wait to hear some in the wild.
EDIT - would actually be good to hear from cenk for some clarification on how exactly he was implying mastering.... I took it he was excited and maybe slightly carried away with his sales pitch and actually meant along the lines of a final mixdown.
