cost no object integrated amps


folks,
what are some cost no object  , no compromise super integrated amps that rivals separates. would love to hear some thoughts, ownership experience and which ones must be considered in the shopping list.may be in 30k to 60k price range
 some of them which come to my mind are

1. dan d'agostino momentum
2. audionet HUMBOLDT
3. soulution 530
4. dartzeel CTH-8550
5. ch precision I1
6. vitus SIA 30

feel free to add or suggest any other ones. or if someone can comment on each of these or rank in the order of preference with their reasoning.

My brother has a Gryphon Diablo he got it for around $15 k 
I have not found anything at even low $20 k range that sounds that cohesive .
having the size to keep things properly isolated and premium parts quality when you are not under price constraints , like others mentioned less power cords and interconnects , and the synergy of the amp preamp in one chassis truly 
make sense .when he is ready for another upgrade That would be my end game setup.

+1 for the Gryphon Diablo 300 to the owners of them https://ibb.co/Px6dd9W, it would have to be something very special that I’ve yet to see/hear to top them.
