Yes I tested it. Full Marduk brings song recast timers from 24 secs to 22 secs. Brings Mazurka recast from 1m to 57 sec. It's a far far cry from an all out haste set on BRD but for situations where that's not required I think that it will be a good gear set. I don't have a dalmatica so the refresh + relic ballad is a very nice bonus for me.
and it's the Allure Ring +1 that Muteki gave me as a present when Ruke and I got married in game.
