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!
