unison Reasearch intergrated vs Rogue amps

Been looking to upgrade my old Arcam alpha 8r after many years. I like detail and separation and the arcam has been struggling deliver when the music gets meaty and dense for quite some time.

Would like some opinions from the community. Been doing some research and I've narrowed it down to the Unison Research intergrated hybrid amps or the rogue series of amps such as the cronus magnum, rogue 99, or pharaoh.

Any opinions out there? any one listen to unison Research series? or can compare the rogue amps to them?
