Monitor Audio IMO will be the closest to the Paradigms, maybe a little smoother. Revels sound great but are kinda dry sounding but very nice IME. Also Revels will be harder to drive I think but you have some good Bryston power so shouldn't be an issue. 6k could get you into any of these brands upper level speakers. Only ever had a short demo with the Maggies so no opinion on those.
Monitor Audio PL200ii or Paradigm Persona 3F could be found used in your range.
