hello caphill,
first off, congrats on owning the dCS Vivaldi stack, it is wonderful sounding digital. certainly considered by most to be among the best sounding digtial choices, and obviously at a high price point too.
and you have a system that can fully take advantage of top level digital, congrats on such a top flight system.
i have no opinion about the newest Esoteric Grandioso gear, i heard the newest Esoteric gear at the L.A. Show but it was the level below the Grandioso.....which was good but it’s a show situation so hard to know what is doing what.
since you already own top level digital, but for whatever reason seem to not be fully satisfied, i would like to mention a different product that I think sets the standard for digtial performance, the MSB Select II dac.

i own a Select II with a single power supply and the Femto 33 clock upgrade. there will be a matching transport coming out soon.
I think that the Select II would sound great in your system.
my system is focused on ultimate analog vinyl and tape, and I can tell you that the MSB Select II looks analog straight in the eye. it has astonishing performance and goes places I’ve never heard digital go. I heard the Select II 2 years ago at a show and then tried to find a more reasonably priced alternative, but could not and so gave in to my desires.
best wishes on your quest, and hopefully someone can help you about the Grandioso question better, but in the price range you are playing, you might as well think about the best possible digital.
I don’t know where you live, but if you get to the Seattle area you would be most welcome to visit me and listen to the MSB Select II for yourself.
cheers,
Mike
