Floor standing or Large bookshelf recommendations - 2.0 channel setup


Greetings, I have a parallel thread in the Amps and Preamps section for this same setup. I trying to build a step up from my existing 2.1 channel system. Recently a major change that has happened is I finally took the plunge and got myself an MC152, so now that my amp is not a variable, I’m open to exploring speaker options. (I like warmer smoother sound, with a little sparkle at the high frequences. Currently quite happy with the type of sound I’m getting with MC152).

I currently have a Rotel RA-12 Pre + MC152 -> LS50 + SB2000
Room dimensions: 17’x13’x12’ 

The LS50s really came alive after adding my recently acquired MC152. But now I’m in search of a pair of good floor standers or large bookshelf. I intend for this to be a long term setup so I am ready to wait and not in a hurry.

Here are the ones I narrowed down so far. I’m going to be using my local dealer so I wont be able to audition some of these. I understand Crutchfield is an option, but thing is I have very good relationship with this dealer and wish to give them business:

(Budget prefer to stay under $5k, cheaper the better really)

Dynaudio Evoke 50 - Not able to audition, but read these are not as sparkly on the top as B&W D3 series

B&W 805 D3 - Auditioned these, loved the treble, but worried it may be too much over time. However since I’m looking at tube preamps, I suppose that should tone down the sharp highs. Second thing is I feels this model will hold better resale value / easier to get rid of it comes to it ever. Open to thoughts

Focal Aria 936 - Never heard them, but they seem to be on quite a good promotion right now. Heard these tend to be more on the sharp side with less bottom end. These are low on my priority unless someone can tell me otherwise.

Salk Song3- Wife does not approve the looks of that... this is going to be a tough sell

B&W 704 S2 - This one is strictly on the list because I have local listing of a almost new pair for under $2k and I just see that as a great value. But I not sure if its worth looking into these just cause its a deal.

Am I missing any other major contenders? Please share your thoughts on the ones I picked and if anyone of those or other particularly go well with my type of setup. Thanks and Cheers!

+2 b_limo. Regarding the improving preamp vs. a speaker change question, yes speakers have much to say about the character of a system, more so than other components, however all components share in the quality of said system. You seem to be fairly happy with your system now. At that point an upgrade might best be accomplished using the weakest link approach. You are not in a hurry, think it through and explore your options. 

What are your sources?
@OP the B&W 805’s stand mounts absolutely sound much larger than they look. They make many floor standing speakers sound pathetic in comparison. I have the 805d3 stand mounts and I’m often blown away at how massive they sound. Also, it’s one of the most beautiful looking speakers out there in my opinion.
Have you considered Paradigm?  Pick up the small floorstanding Prestige and upgrade the pre. I really like my parasound.  My friend enjoys his mix of Klipsch with McIntosh. 
Without a question the SALK Sone3 Encores.  Heard them at the RMAF and they beat out speakers costing 6 times more.  The Focal 936's are horrible and the BMW's lack a lot of bass.  If you talk to Jim Salk tell him Larry Edwards sent you from Denver.  He is an incredible guy and he knows what he is doing.  He sells direct so he does not have to give up his profits to the dealers and he also does so in order to use the best drivers for the money.
Im sounding like a broken record, but when paradigm runs the sale the persona b is really good although I haven’t heard them with Mac gear.
