Recommed a medium sized monitors that can go loud


I want to downsize my speakers from a floor stander (Acoustic Zen Adagios)to a "medium size" monitor or "MAYBE" a slim profile and light weight floor stander that can play loud, but also sound clean, transparent, and musical.

I have a Rogue integrated hybrid amp(100RMS) and a Ayre CX-7e mp CD player. So far, I have considered: KEF LS-50; Harbeth 30.1;.... Harbeth new SHL Super Plus( too expensive).... Monitor Audio Gold GX-100; Devore O/93 ( too expensive and possibly overrated) Scansonic MB-2.5; B&W's 804 or 805; KEF 300R; I can spend about $3000-3500 for used mint speakers, possibly a little more.

Please note: I saw two separate ads on Audiogon for KEF LS-50's that sold within a week; yet. I cannot believe that these speakers have any real bass or don't sound bright or lean..... Thank you.

Look into the PMC Twenty series.  I just purchased a set of the 22's and all I'll say is WOW!  
I have a pair of Dynaudio focus 160s for sale. While not as efficient as some of the others mentioned, you can feed them many many watts, and they will play loud. They strike a nice balance between hi fi and listen all day. They really are the jack of all trades.
I'll second the Ascend Sierra 2.  They are a brand that flies under the radar as they don't have the brand appeal of a Focal or Monitor Audio.  But that's just marketing strategy, and Ascend spends their money on the product instead.  The Sierra 2 puts many bookshelf speakers to shame.  If one wants detail with clear effortless reproduction, then these should be on the short list.
