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

I have owned for a few years now the Carver M350 mono blocks. I have looked at the insides, the wiring, build quality and to me it all looks excellent.

Before the Carvers I owned the Atmasphere M60-3.3 and before that a Pass Labs X350.5 solid state.

The Carvers sound quality was/is a large sonic improvement over those amps. BTW, Bob actually came to my house for a few days. He is getting up in the years, and I doubt he is looking to cash in on his designs these days. The man has a lot of pride!

I used the benchmark with the KEFs but preferred an Ayre K5xe

I have the Carver 275 amp and think it sounds terrific.  It does run relatively cool.  Give it a try as they have a generous return policy.

Carver for sure. It’s made in the USA too. 

I can’t speak to the Carver unit, but the Benchmark and Rogue units should both prove fine, but with somewhat different tonality. Also I echo the comment of @avanti1960. The Rogue Stereo 100, which I ended up purchasing, to me is audibly better than the Atlas. The 100 had more clarity and better transient response. More than enough power in the Rogue or Benchmark units. Can you borrow the amps to audition at your home? That will certainly help you decide.

As to adding one or more subs, should you be interested, the REL T/x series are a good match, musical, and REL recommends using high level inputs, wiring to the sub from the speaker outputs on your power amp rather than a low level input from a preamp. (REL provides the necessary cable with their sub or you can purchase an upgraded cable.) So your purchase of the Rogue preamp does not preclude adding one or more subs. I think you will find many if not most Audiogoners with REL subs use the high level output.

Happy listening!
