the spatial info ( what there is horizontal and vertical ) is already encoded in the source.
the waveform is complex and includes both fundaments, harmonics and the time and phase information in the waveform.. IF you have not spent anytime in a studio, page thru your album LP gatefold covers and look for microphones, ten -15’ off the ground...Rudy Van Gelder of BlueNote fame, famous for this....or look at symphnony recording microphone placement, especially well done stuff with less than DG 30 microphone stuff.....
so to properly reproduce this complex waveform we need to simulate a point source wave launch, would be good IF we do that at ear height, unless you want different arrival times...which is audible. The more drivers ya add the more different arrival times ya get a coincident driver solves part of this problem and introduces other wavelaunch issues like bouncing HF off a lower frequency moving surface....ponder that as you invest in cabinets and footers that dont move....
The Vandersteen setup and engineering depend on an accurate measure of listening ear height, most other speakers will benefit IF you know this dimension.
they are not just a good choice. I would not hesitate to put Quattro CT up against any KEF product and there would be MORE $$$$$ left over for electronics, etc
listen to any number of great recordings w spatial info encoded...Live in Paris is one such IMO......does Diana Krall really need to be another 2’ taller..
Keep selling the reflections OFF a big tall box....
your admiration Troy for the brands you carry is understandable, you have a Vandersteen dealer a few miles from you. The world thinks they are more than a good choice. Your competitive urges cloud your thinking....Let’s meet on neutral ground, say in Munich where we can listen to both..my guess is Helmut Brinkmann will get great sound there with his 7’s
and yes for some people the KEF are a great choice.
The whole notion of the singer must be at ear height is absurd . Why does the performer , singer , guitar player , drummer have to be at the same height as ones ears ? Makes no sense to me and actually seems unrealistic . Would a singer be sitting on a couch as to have the sound of their voice be at the same height as me . Seems more realistic if they would be standing , which means a foot or two higher than my ears sitting .
Gee Tomic so a speaker lower then ear height with an agreesive rake angle is better than a wide dispersion true point source which may be higher than listening height based on what?
Listening height is dependent on couch height, listener height and distance from the loudspeaker as well as the dispersion of the loudspeaker.
You miss one super valid point for $30k less money you can get an pretty darn good set of amplifiers and a preamp to boot.
A properly set up pair of Blades is pretty awesome which loudspeaker is "better" is up to personal interpretation.
We also sell the Legay Aeris and they are a ridiculous value for $25k you get a speaker with full active bass, full room equilization, and 96db efficiency, these are an even better deal than the Kef Blades as all you now need is a set of amplifiers and a streamer, the Aeris comes with a Wavelet processor which is a pretty good dac, preamplifier and room correction processor.
Your love of Vandersteen is admirable, but they are just one good choice out of a sea of great loudspeakers, which include the brands we sell and those that we don't.

@jetter yes and what if the performers were the Dead with 60’ high wall of sound ?????
i do have some bootleg cassette from that era......will check after I build a 57’ tall stand for the KEF 105.2 I have lying around here...somewhere.....
speaking of music, just enjoyed 8:17 of Loggins/Messina - Same Old Wine at 39 volume on the ARC into the 1.2 KW a side 7’s w Vandersteen amps......holy cow......
big fun.....
also, so much for KEF dealer expertise......building a big speaker taller than ear height not needed.......

I have 5A carbons. For 25 years my wife put up with my audio habit and its intrusion into our living room. She would listen but it was never a big thing for her. Three days after the 5A carbons were installed I came home to find her listening with the lights dimmed and a candle going. The first words out of her mouth were "you HAVE TO hear this song on THESE speakers." A complete transformation in attitude and interest. Now she listens to her favorite music after I upgrade or tweak and gives her opinion. Her latest text started off with "the system is sounding particularly amazing today" .... (this was after adding a couple of AQ Hurricane AC cables .... another story....)
The 7s tunable bass, balsa wood drivers and stealth enclosure combine to make one amazing sounding speaker. I spent a couple years going shows and dealers before I pulled the trigger on the 5A carbons. There is only one speaker upgrade I want and its the 7s. This year hopefully.
looks like the 5a Carbon is now out of production....used would provide stellar value.... before buying Blades seek out used 5a Carbon or talk w dealers about what Vandersteen model ( forthcoming ) will replace it..
Just my $ buck-fifty..

OP, if you can afford the Vandersteens... they are absolutely outstanding. In the uber expensive department speakers I've heard, properly set-up they are just unreal.
The Blades are OK. I've heard them outperformed by lower priced speakers. They are not bad, just wouldn't be my first pick in that price range. Frankly, I would to the legacy's over them on a pure sound basis. I like the Vandersteen 5a Carbon a lot better at that price point.
If I had a killer loft apartment in NYC, wanted something to look unique and sound decent, I could see getting the Blades, they certainly make a statement.
If you go to the shows and meet with Legacy, talk to them. They have always offered nice deals to show attendees I've found.
But, if you are going to drop that much cabbage on speakers... ultimately I would make sure to listen to them.
@gdnrbob. Totally different rooms and systems... the Quattro in the largest room they have and powered by the new smaller solid state high Pass amp sounded very very nice. i hung around dges giving others the great seats the Treo were in a smaller room - about 15 x 15and had big time slam with the sub 3 i left wanting to somehow squeeze a sub 3 into the condo and squeeze the amps in budget also.... fun i am back in Seattle tonite so I will fire up the 7’s and enjoy some music
Fantastic event last eve with Richard Vandersteen at Stereo Unlimited in San Diego 7 mk 2 with Richards unique high Pass amplifier running along with Quattro and the more affordable m5 high Pass amp... fun treo CT with sub 3 w 11 bands of analog EQ HRS also represented by Michael Latvis, great sound, hospitality and 100+ people there till ten at nite.
I have not heard the Blade but the Vandersteen 7 is one of the best speakers I've ever heard, along with the Vivid Giya and TAD Ref One. At this price point, airline tickets to hear for yourself seem like chump change!
Here is a perspective from a Kef dealer who has the Kef Blades and have used them at a few area shows.
The Kef Blades will match of equil any $60k-$100k set of speakers if you set them up correctly and personally do not see the advantage of the Vandy 7 being much more expensive for a speaker with lower efficiency, less power handling, and a lower and smaller soundstage.
The Kef Blades were developed at a price tag of $4 million dollars, by some of the most respected engineers in the world, they are a true point source where all frequencies including bass emminate from the same point in space.
Our setup in the 2012 New York Audio Show with the Kef Blades, a $30k set of Chord mono block amplifiers, a $20k Chord preamp, a $22k Esoteric Dac with high end cabling etc the system's price was about $150k including turntable.
Down the hall GTT Audio, $107k YG Sonja, Solution amps $80k, Solution preamp $40k, Solution Dac and transport of similar very expensive digital, $40k turntable total system price $400k or so.
We were expecting the YG/Solution system to be better it wasn't it was different not better.
The combination of huge soundstage, very good image placement, good top end extension and deep tight bass for $32k makes the Kef Blades a bargain for high end loudspeakers.
Just consider that the huge $30k price difference between these two loudspeakes would get you a pair of Blades and a really top notch amplifier and preamp.
As per tunning yes the Vandersteen's do have tunning in the bass which is a fantastic thing, so does the Paradigm Persona 9H which can be totally tuned by Anthem's ARC program to cover way more frequencies than the 11 band parametric eq that Vandy uses.
Also for $25k you get the Legacy Aeris which goes very low in the deep bass and also comes with a dac, preamp, crossover with Bohmer room correction which compensates for both time and frequency issues.
The issue with the Blades is the same issue we have raised with the Paradigm Persona and B&W and Focal, these larger companies will allow dealers that may not have the right matching equipment or rooms sell their products not to mention at shows they don't necessarily use the optimal matching gear only from vendor partners that they have a relationship with so again the pairing might not be optimal.
You need to come to a good dealer and here a well setup pair of Blades for yourself and if possible use a similar level of gear then what the Vandy 7 dealer would be using, so if the Vandy 7 are being played with $50k worth of electronics then you shoud be seeking a similar level of setup not a pair of $32k Kef Blades on a $5k integrated amp or just whatever.
The Vandy's have a very smooth liquid sound and are very engaging, a well set up pair of Blades won't be quite a warm in the midrange, however, they will sound super clean and accurate with a gigantic image and when tuned appropriately will be very smooth and musical as well.
With thirty thousand dollars of distance between (not considering the difference is typical amp pairing) them I have to wonder from a marketing perspective why these two particular models are of interest.
OP - You are getting sound advice from those posting above. Trust your ears, BUT... settle in and listen for a l o n g session. Which speakers make you want to stay or keep a smile on your face.
I have no experience with the Kefs but have owned Vandersteen's for the last 30 years. I just go into my listening room and enjoy the music. No "hifi" from them. They just play the music. Oh, and I smile a lot!🎼
Per several dealers and people I trust the Blade 2 is the better speaker overall than it's big brother and it compares performance wise with the Quatro and maybe the 5A. Don't think it is even in the ballpark of the 7 Mk II other than cost. But as most every other poster has said get out and listen for yourself as in this price range it is worth the price of a plane ticket if necessary.
I have heard the Vandersteens at a dealer and the Blades at RMAF and can’t put them in the same category. To me the Vandys are hands down better in every aspect. But as mentioned you need to audition them yourself.
Never heard the Vandersteen 7 but owned both the Vandersteen 2ci, 2ce signature and the 3A. I did hear the big Kef Blades and found them exciting at first but fatiguing after about 30 minutes of listening. Knowing Vandersteen, I would think that would be the better of the two but you really need to listen to them, especially at that price range.
At that price range, you do need to audition them both. I can say that one of the two or three best systems I have ever heard was Vandersteen 7 Mk IIs with their amps and subs at Audio Connection. I have not heard the Blades, though.
yes, how blessed and fortunate. I am lucky to own several pair of Vandersteen, including the mk II. I get endless hours of enjoyment from them in a mostly all digital system. I use a Revox B-77 and Master tapes as an analog reference as well. I have visited most of the USa dealers who display them, all quite competent and excellent support. They all carry IMo excellent ancillary gear, most are very analog oriented. I might be the blacksheep..ha I have also heard the Blades, I never say anything bad - go listen, form your own opinion.
what room, music, volume level, upstream equipment?
enjoy the journey !!! and the music
IF I may be of service, just let me know. IF you get to Seattle, you are welcome to hear ours.
Lucky you.....personally, I would choose the Vandersteen, however only you can make that happy decision. I own Vandersteen and have been very happy with their support, I don't know Kef support....that might be put in the decision making.
Vandy's, always Vandy's.-Especially when considering how you can tune them to your room. Seriously, if you are spending that much, why don't you audition them? You are the only one that can make the decision, as everyone has different tastes, hearing ability, etc.
