Well, my personal preference out of those choices (I've only actually heard Vandersteen 2Ce Signature IIs, Monitor Audio RS6s and the Triangle Esprit Esw Celius) would be the Vandersteens, but my ears and aural perception may be much different than yours.

Good as they are, I would characterize the Vandies as being much more laid back to the point of snoring and boring (for me)compared to the Monitor Audio or Triangles. I haven't heard those Logans.

Not sure if Jackfish would agree with my comparisons.

Hope this helps.

Yeah, the RS6s and Triangles do have more sizzle, if you like that sort of thing. I guess some people might consider uncolored or neutral snoring and boring. The OP's ears are the ones that count here and which of these loudspeakers will satisfy depends on what they favor. Its too bad they can't audition some Vandy 2Ce Sigs somewhere. That said I could live with the Monitor Audios as I have been considering them, but I'm going in a different direction.

I've only heard the RS6 and the 2CEs. Both sounded good. It all depends on your listening level. The 2CEs were very room filling and needed more power than I had to drive them plus they had to be driven at levels too loud for myself...but they most enjoyable to listen to. They RX6s sounded best at my listening level and didn't require as much power to drive them. Also consider how large a room the speakers will be in.
