best used floorstanding speakers under 5k that has small footprint


I am currently using a pair of ATC scm40 v1s and are looking for upgrade them. I love its mids presentation and I mainly listen to vocals and occasionally piano and cello (no orchestra).

My budget is $5000 for a pair of used floor standing speakers, might be able to stretch a bit based on specific cases. 

The ATC 40 v1 is still relatively small in footprint as a floor-standing speakers, I would like to keep this trend in my next speakers. 

Let me know if you have any recommendations. Thanks!

@steve59  The 50s would be nice but they a a bit too large (mostly in depth) in my living room. Thanks for the suggestions though! Would love the mids of 50s if I am in a bigger house!
It’s hard to find speakers with mids similar to the ATCs except by going up the line.

What improvements are you hoping to get over the SCM40s? More bass for the same footprint? Probably unlikely without a bigger cabinet.

Things I’d look into are adding a good sub (or 2), upgrading the SCM40s to active, upgrading them to the v2 new tweeter (I’d email ATC to ask if both these are possible to retrofit from the v1s)

Also, what amp and sources are you using currently? Biamping or triamping might be another idea.

Just scouring the current listings of floorstanders in your budget on Audiogon right now and nothing jumped out to me as a real upgrade.
Thanks a lot for your response!  @motokokusanagi I don't have many complaints about scm40s except that it needs lots of power to drive. I want to go for a pair of used scm40 v2 or scm40a if good deals turns up. The scm50s are a bit large for my listening area. Thanks for the suggestions!
What size footprint are we talking here? Women's size 8?
A good amp is a must for all ATCs. Upgrading your power amp or biamping might be a real option if that’s one of your issues. The ATC P1 and P2 power amps (and the SIA2-150 integrated) are great matches to the passive speakers, and come with the link feature to enable easy biamping/triamping, though this can also be done with any suitable power amps running the same gain with some splitters off your preamp outputs.

Then again, for the price of an ATC passive + amp, one could usually have gotten the active speaker version, which should be superior.

If it’s possible to get a loan/trial, I’d experiment by seeing what improvements a single high quality power amp can bring, or even 2 x identical high quality power amps would do biamping; driving the woofers of each speaker from one amp, and then the tweeter and mid from the other amp.
Check out Spendors. The A-line and D-line have a small footprint. I have owned Spendors and they are an outstanding floorstanding speaker!
V2 of your speakers, spendor, vandy treo, joseph audio...
Vienna Acoustics Beethoven Baby Grand.  Perfect for the types of music you prefer.
@motokokusanagi if I can find a 40a used somewhere I would jump on it. For now my best bet is get a 40passive v2 paired with ATC P1 or P2. Thanks.
You might want to check out the Elac Navis towers. I know they are under your budget new. They really are phenomenal and having listen to both speakers I’d take them over the ATCs which are quite good themselves. Plus you can sell your amps and buy more music!
Spatial Audio - open baffle dipoles with no box.  Three inches deep, 17 inches wide. Sound awesome 
Spatial Audio are nice sounding speakers, Vandersteen Quattros and 5s are smallish footprints, so are Verity Audio and Nola speakers especially with the Alnico drivers.
Totem Acoustic makes great sounding speakers with small footprints.
ELAC FS409 here for $4790.00 look and sound great check it out.
Spendor, Proac, Joseph Audio, Verity.
I have a pair of PSB Imagine t2 speakers and enjoy them....musical, good imaging and decent soundstage. Have seen them on ebay for 1500. New they are about 3500.
yeah the seas kit offered by Madisound Bifrost,,  heck under $2K
Only 1 condition,, need a  good push pull tube amp/integrated. , say a  mid size PL, Cayin or Jadis
Thanks for all the suggestions. I forgot to mention I mainly listen to male vocals
@yuhengdu_tiger , 
It shouldn't matter what you are listening to. 
A good loudspeaker should perform equally well with any music.
Thanks. How about the Tannoy Cheviot? They look interesting and can fit into my living area nicely. I am wondering how it compares to ATC scm40s
