Ken,
The Grandioso stack in the big VAC/Von Schweikert room at CAF 2021 did sound amazing, no argument there....that setup was the
Grandioso P1 and D1 generation, Esoteric's top offerings until Spring 2019 when the P1X and D1X were brought out; the move being
a change from AKM 4495S DACs (16 per channel) to Esoteric's new in-house designed and built DACs and a few other upgraded features.
The Audio Company did a great job showing P1 / D1 at its best, for sure and it sounded wonderful.
Now it's my turn because I installed that exact Grandioso stack at home here on December 30th and could not be happier,...will post photos soon.
