Owners of Gryphon amp; show up: Diablo 300, Diablo 333 and essence stereo amplifier

It will bet interesting as the reviews come in on how people compare Essence separates, Essence amp with a different pre, the 333, and the 300. I currently own the Diablo 300 with Magico s3 mk2 + Luxman DX-10 sacd . No matter how much I read a few rare reviews on the new 333, no one dares to compare it directly to the Diablo 300 and even less to the Essence stereo amplifier ? Although I am completely satisfied with the 300 the upgraditis is still present!!! I understand that you may had the 300, 333 and the Essence ? My main  question is  the difference between the 300 and the 333 greater than if we compare the Diablo 333 with the amp/preamp Essence model ? I don't think I'm heading towards separate items anyway and also would the Essence have enough headroom to drive my speakers in a 23 X 23 listening room ? My dealer Bliss Acoustic Claims that the price difference is not worth the $10K between the 300 and the 333? We know that at this level you have to put a lot of $$$ to hear a slight difference.... My wiring looks like this ; 2 power cord DRAGON, Nordost Valhalla V2 (speakers cables, forget the crap people say about these cables), XLR SILTECH QUEEN 1.5 M. between Luxman and Gryphon.
