Can't comment on the Rockna, but two friends and I spent a couple of weekends comparing Formula demo loaner, his Yggy and unremembered model of Meridian DAC built-in to his $10k-ish preamp. After many hours of listening, both blind and IDed, we all preferred the Aqua by a decent margin. Both well-heeled guys ended up buying Formulas and still love them. FWIW, the one who didn't own the Yggy owned an Aqua La Scala at the time, so he was already a fan of the company(with good reason, IMHO!).
If I ran into a windfall, the Formula and Bricasti DACs would be atop my list for serious consideration. Cheers,
Spencer
