Bookshelf Speakers - $500-$900 range


Just looking for something that can provide a little more clarity and soundstage than my current setup in a medium sized room (!3x17) with high ceiling.. Music preference is rock, hard rock, acoustic music, and female vocals. Will probably be used with a NAD or Rogue integrated. Have the following on my list (new or used as long its within $500-$900 range):

Monitor Audio GX 50
B&W CM1
B&W CM5
Totem Rainmaker
Ascend Acoustics Sierra 1
Kef LS50
Sonus Faber Venere 1.5
Focal Aria 905

I know the recommendation will be to listen and compare them but I'm trying to dwindle the list down. Any feedback is appreciated. Thanks.

Your room is about the same size as mine and my 936's create a deep soundstage that's at least the width of the room along the long wall. I'd suggest 906's instead of 905's. Huge Tool fan here and Adam's guitar work seems to come at you from way outside the placement of my speakers. The 906 will dig deeper than the LS50 too. I'd give very serious consideration to the LS50 though. There are things it may do better by your tastes. 
I have the Sierras and enjoy them a lot. Good, well rounded speakers that can play most anything. Love the soft domes. I listened to both Sierra 1 varieties and also the Sierra 2’s and preferred the standard Sierra 1.

Plus I found a LCR used set of pristine gloss cherry for $750 so great value as well.
I would also consider the PSB Imagine Bs. I use a pair with my old NAD T747, Raspberry Pi streamer, and Cambridge Audio CXU universal player and they sound great.
You might want to add the Martin Logan Motion 35xl. An underrated speaker I believe. If you can find any Gallo Classico CL2 I don’t believe you can do any better in this price range. Another overlooked gem. Compared them side by side with the LS50’s and I preferred the Gallo for their better, wider and more holographic imaging, more neutral/detailed presentation and more energetic sound. Also had cleaner, more solid bass than the KEFs.
