Best Speakers for Nearfield Listening $4k or Less?

I've researched everything available here on the topic and all of the threads related to this topic are three years old or older. The only meaningful exception is a somewhat related thread to what I am asking, which, oddly enough, I posted on behalf of a friend about a year ago. While he now has unfortunately relegated to a room as small as mine, which I have been living with for years, he also has greater financial resources, as you will see. For reference, here is the thread in question.

He has a real love for the Harbeth sound, and did a lot of listening to many options (he travels frequently). We also continued our discussions at length. In the end, what really got his attention was this older forum comment:

"05-17-08: Jeffkonicek
I had the opportunity to hear the Harbeth M40s at a true nearfield, (about three feet away, and 5 feet apart) in an acoustically treated room. Matching REL Stadium 111's, tube amplification, state of the art turntable ( sorry, I don't recollect more specifics ). Let me just say it was a transformative aural experience. As big as they were, when I closed my eyes those M40s just disappeared! I could almost reach out and touch the musicians as they played. Startlingly real 3D sound stage."

And then there was the comment from a gentleman in Chicago with the same exact scenario, which also includes a picture, if you scroll down:

It took some time, but about four months back, my friend located a great deal on a pair of Harbeth M40's that were traded in to a dealer. Since then, he has been thrilled with the sound his system produces. I've also had the opportunity to do very extended listening to his system and the sound the M40's output in the nearfield is simply revelatory (assuming high quality amplification and

Until now, I've been very happy with my nearfield setup, using the excellent Silverline 17.5's. However, having had all this exposure to his system, I feel strongly that I will have to make a move to remain satisfied, or, hopefully more. Unfortunately, none of the less expensive Harbeth's, such as the superb SHL-5, or even the Compact 7 ES-3's will work in a small room, or even some medium rooms. I've done a lot of homework there, and even discussed it with a representativr from the company, and they are a definite no go. And before someone suggests it, the tiny P3SR's are a lovely little speaker but they will definitely not meet my needs. I was even allowed to borrow a pair, and they simply are not what I am looking for after hearing my friends M40's.

My budget is an absolute maximum of $4,000.00 to be sprnt on used speakers to maximize my buying power which clearly rules out any M40's. So, I'm asking for your thoughts, expertise and recommendations on how I might best accomplish the sound I want.

My room is 10x10.5, with a built in shelf, in front of which the speakers must be positioned. Listening distance is 5.5 feet, and the speakers must fit into an equidistant footprint 5 feet apart forming a triangle with the listing spot.

My equipmemt consists of a ModWright LS100 preamp, a Modwright KWA-100SE amplifier, a Bryston BDA-1 DAC, and Oppo 103, and an Olive 4HD.

In talking to friends in audio, some dealers and other members of the trade, the following speakers have all been recommended, but there has been no consensus. I have also not listened to many of them, nor have any opportunity to. I am open to all of your suggestions, Thanks.

previously recommended by others:

Gallo Reference 3.1/3,5
Gallo Reference Strada 2(and TR-3D sub)
Acoustic Zen Adagio
Zu Audio Essence
Merlin VSM-MX or MXe
Martin Logan Theos/Ethos )which I doubt would work, not to mention requiring a new amp)
The KEF ls50 anniversary monitors are a recent model that has gotten my attention. I like the design and getting unanimous rave review. That looks like a good attempt at a perfect design for nearfield listening for modest cost. I would give that consideration and perhaps save some money for more music as part of the deal.
The KEF LS50s seem to be getting rave press. I realize they are less than you've budgeted, but if the sound is right it could be the bargain of the century. They can be auditioned all over the place...Or just buy a pair here, sae some for $1150 and re-sell if not satisfied - not much to lose...

Suggest-Reference 3A MM de Capo BE. Brand new would be within your price point. Well worth reading the reviews and a demo if possible.
I liked Earthworks Sigma monitors when I heard them several years ago in a nearfield set-up. They are "studio monitors" so they were designed for that purpose and the drivers are physically time aligned. More expensive though than the KEF's mentioned ... I believe they are close to $4k
KEF ls50s aside, I would question the value proposition of spending $4K for good near field speakers. Nearfield listening simplifies everything making it much easier to achieve optimal results. Only headphones simplify things even further.

How many studios spend that much? Why should I?

The KEFs would seem to attempt to take nearfield listening to a very high level, but do not mistake that they are not cheap relative to many common "nearfield" monitors. They are a "statement" type speaker for that application at reasonable cost on the grand scale of high end home audio.
Event Opal active monitors powered by near 700w per each speaker immediately turned my attention for excellent imaging, clarity and precision.
There are many that will work. I have been living with a small room (11 X 12) for 17 years. Been through plenty. You need to widen your search. Search speakers for small room, small room, etc. A LOT of discussion on A'Gon about speakers for small room.
Right now I am using Devore 3XL, sound great. Harbeth Compact 7es have worked beautifully there too. Not sure where your info on es7 not working in small room, but Alan Shaw designed es7 in a 3m X 3m room to work in a small room.
no Quad ESL suggestions?

Best nearfield speakers ever.

If you get a used pair of rebuilt 57's or 63's. I love the 988(9) as well.
Harbeth compact 7ES3 best of all anteriorly mentioned,
I run them with 20 class A luxman 550 AII, absolute heavenly match,
Good luck!
