Suggestion between benchmark Ahb2, Bob carver crimson 275 and rogue atlas magnum 2 amos

First ever post here. I have a peachtree nova 150 integrated amp, KEF LS50 metas, a Bluesound node, a vintage technics turntable and a schiit mani phono preamp. I am making the move to a separate amp and preamp. I have a preamp (a rogue rp-1) on order and I’m looking for an amp. I think I have it narrowed down to a Benchmark AHB2, a Bob Carver Crimson 275 or a Rogue Atlas Magnum 2. would appreciate any input the group might have or any alternate suggestions.
