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.

Are you using a sub or pair of subs with those nice but small and inefficient speakers?

I do not see pre-out/main in on the rogue rp-1 preamp on order. That is what you would want to go out to a stereo pair of self-powered subs, send the bass load away from both your amp and your KEFs.

then, I would go with the Carver, stick with tubes to drive the KEFs, subs drive themselves.

Anyone considering a Carver Crimson should take a good look at this thread:

Since you've ordered a Rogue preamp, your best bet for synergy and success would be to pick a Rogue amp suitable to you speakers and budget.

Stretch a little for a new or used Rogue Audio Stereo 100.

Even though it is rated for the same 100 WPC as the Atlas, the St 100 sounds twice as powerful (better power supply circuitry).

The ST 100 is a reference quality amp that solid state cannot match IMHO. I had the 100 and sold it to buy a Pass Labs amp and still wish I had the 100. Just a dynamic, special sound.
