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
