Vitus sia 025 vs d'agostino momentum


Hi everyone
i need some advice on this one. I have devialet 400 monos and I’m looking to get an integrated amp. I have narrowed the search to vitus sia 025 and d’agostino momentum amps. I am hoping to get advice on choosing between these two items.
My system
focal Scala v2
2 REL g1 subs
brinkmann balance tt
brinkmann 12.1 tonearm
benz lps
shunyata triton/typhon
transparent reference cables
audio alchemy phono
dsc rossini
The reason for the change in amps that I feel that the devialets lack any depth to the soundstage and my system is too technical. I have heard these amps and they seem to add better scale to the soundstage and a more tube like sound
any suggestions?
thanks in advance

i heard there is only 2 us authorized dealers. One in New York and the other in Orange County. I only know of the one here on the west coast. It's cake audio. I heard the amp in the Newport show a couple of weeks ago. Sounded awesome.
also thank you audiolabyrith for your detailed review. I'm leaning towards the vitus. The momentum is a great amp but I thought it was a little overdone. I have been told that It could cause fatigue to listen to.
Dodo try the gryphon Diablo 300
i swapped my Vitus sai025 for one
chalk and cheese imho

Forgot to say...
i have an aurender x100, lampizator golden gate 7, gryphon Diablo 300, and until recently focal scala utopia v2
Happy listening!

One issue with the excellent Vitus amps was that they need to be left powered up as they take 3 to 4 days to reach their transparent sound
my Diablo 300 takes 30 minutes although I do leave it on standby

Have heard the beautiful d'agostino with Magico speakers
Impressive but bass less warm than the Scala v2 or my current Zingalis client name 3.12

hope this rambling is of some help or interest
