Compact Floor-standing Speaker Recommendations under $4k

Thanks everyone for your feedback! 

Definitely some brands/options I hadn't considered or was even previously aware.  The Salk & Ascend Acoustics seem interesting and similar offerings from engineering focused speaker design.  

Also with the Spendor A7's although they are now over $6k new just a couple years ago it seems they were closer to $5k new and I've seen some second hand in the $3-$4k range so thought it might be possible.  

Does anyone have experience with PMC floor-stands? Saw some good reviews in WhatHiFi and a few other sites, but then some terrible feedback in forums so not sure if those might have just been one off's?  
@henry53 I agree with you completely, I'd really like to avoid paying full MSRP as I think many great values can be had in the secondhand or even past floor models. 

Thanks again for all your feedback and advice! 

So many smaller speaker companies I wasn't familiar with so I'm trying to research all the prosed options.  I know it's going to be system and personal preference dependent but you've all given me such great starting points.  

The Spendor A7's are still high on my list and I've seen used offerings within my price range (several on other sites around $3.5k in what appears to be excellent condition; the MSRP seems high but at the second hand price it might be a much better value proposition). 

The Salk (which I think now makes the Philharmonic BMR's as well), ATC, Verity, ProAc's and Acoustic Zen are all in contention.  The Sonus Faber recommendation also is intriguing, but there seems to be a real love/hate impression on their speakers overall...although I must admit they look beautiful it seems a bit riskier to try them out without demo-ing first. 

And as far as the questions as to why floor-standers.  I suppose ultimately, that's not critical however I was thinking it may be easier to get better bass depth with the floor stander additionally I believe the stand itself is critical to the performance on bookshelf speakers and from what I've seen the stands alone can easily get into the $500 - $1k range which ultimately reduces my budget for the speaker itself.  Now my logic may be slightly flawed so I'm open to bookshelf suggestions, however I was trying to narrow my scope a bit or I open the flood gates to possibilities.  

Thank everyone for all the continued advice! 

Spendor A7's are still near the top of my list and found a pair within my budget through a private listing.  On the other hand also found a dealer demo pair of the Spendor D7.2's a little over budget, but not so far that I might still be able to get wife approval.  Anyone have experience to compare these two directly?  Just because the D7.2 is more expensive I'm not sure it automatically makes it better. 

Also found a ProAc dealer that has a D20R that I can demo in store [granted it's a 4hr drive but still think it's likely worthwhile].  

Finally I came across a brand I previously had no knowledge of....Jean-Marie Reynaud [JMR].  Does any one have experience with their speakers, maybe specifically the Euterpe Jubile?  From their own website they sound like they could be a very good fit, but I'm having trouble finding many reviews or personal experience.  

Thanks again! 

@mijostyn Thanks for the room acoustic device.  I completely agree that I probably am not achieving perfect room acoustics, however I have to work within the aesthetics of my wife as my setup is in our main living room.  WIth that being said, my room is about 14x28x8 and the speakers are about 10ft from the side walls.  Additionally I have two very large & heavy Persian rugs on the floor as well as some curtains hanging behind my listening position.  I'm unable to put anything on the ceiling so have that as a constraint.  With that being said i'm open to other treatment ideas.  

@doni glad to hear of personal experience with JM Reynaud and Belles combo working well.  I've had a hard time finding reviews and personal experience as they seem to have very limited North American presence.  However from what little I have been able to find the Cantible Jubilees do seem like a very high contender. 
Unfortunately it seems like their pricing has increased a lot recently and now retail in the US around $6k....maybe a demo pair if I could find one would be closer to my budget.  Do you happen to have any experience with ProAc or Spendor as well as they are currently also frontrunners based on availability and consistently positive reviews, but would be nice to know a comparison between the Reynaud's or how they pair with Belles. 

Thanks as always! 

Hello All, 

I thought I'd give an update and share that I purchased the Spendor A7's and have been quite happy overall.  Ultimately, I was able to hear a pair of Spendor A4's locally in someone's home and liked the overall sound so thought the A7 could only be an improvement.  The only other pair I was able to hear in person (again through a local acquaintance) was a pair of Sonus Faber Sonetto's. While I did like them (and they look beautiful) they seemed a little too relaxed. 

I think many people might also claim that Spendor's are too relaxed or "Pipe and Slippers" as I've heard them described but I've found them to be quite dynamic and lively so perhaps just differences in models. 

I'd still really love to hear the ProAc D20's , anything from Salk or Ascend or also the JMR's but it just hasn't been feasible.  So ultimately, in the end I took the safe choice in going with the A7's (assuming they would be at least similar to the A4's).  I was also able to find them below my budget.  Are they the perfect speaker or even the best in my given constraints...maybe not, but they have definitely been a step up from my B&W's and I think a step in the right direction to what I'm hoping to achieve.  They have a significantly more well rounded and deeper bass and have not had any fatigue issues.  So overall, I'd say it's been a positive step on my hi-fi journey.  

Thank you all for the advice and help!!!
