Ah, you mean like Apogee, e.g. Diva, Duetta, etc. (plus each and every model gave me the willies)
That's where citation indexes come in handy.
Now how often is that Otala paper on PIM been cited in peer reviewed other papers?
Citation indices can mislead, as they do not distinguish between positive and negative citation. This has been pointed out as a potential flaw in any attempt to use citation indices as a measure of research quality.

Fortunately, John's amplifiers won't be bothered by the poorly-controlled impedance. They have very low source impedance and high current capability.
Atkinson's dancing at the end is a classic of the genre.

You're thinking here seems to be limited.
I'm talking main monitors like ATC SCM200 or 300 or equivalent PMC or Questeds.
No in-built amps as they are rack-mounted and portability is non-existent since SCM200s weigh 116kg each.
Also no class d amps, ATCs amps run in class a until they exceed 2/3 of rated power output which in this case is 275W for each of the two 12" (15" if you go for the 300s), 200W for mids and 100W for the tweeter.
PMC use Bryston amps while Quested use MC2 Audio.
Sound quality wise any of these run rings around over-priced audiophool fare like Wilsons. They are also cheaper despite including amps.
If you really are after nearfields I'd buy Neumann KH120 or similar sized ME Geithains over KEF LS50 every time and still no class d amps in sight.
If you have issues with silk domes (I don't) there is always Genelec.
Apparently. ATC, PMC, Class A and Bryston are all 'audiophool' darlings, highly rated in Stereophile for example. And praising Class A over Class D in principle is the essence of audiophoolery.
I'll agree with Genelec over the LS50 in a heartbeat, even though the latter's measurements aren't much different than many 'pro' audio monitors in its price range. I really, really wanted to like this coax but never heard it live up to the hype.
Don't bother, how much mileage can folks drag out of showing that a 741 is not good for audio. If Barrie actually responded directly to John's last comment he would not like what he heard.
Obviously the best studio monitors in the world like ATC will sound great. I was talking about the ones I have actually seen in musician stores, like Adam, Dynaudio and Genelec. I also wanted Genelec to sound great, being half Finnish, but no.
Another thing I noticed, the ATC tweeter is not very impressive, not even in their best speakers.. The ATC 75mm dome midrange is very nice, although I have not heard them since I got the JA6681B compression drivers. I don't know about their woofers, except that the woofers need a lot of power in general. I was speaking to one of their engineers and he actually recommended me to get an active crossover instead of the built in one in one in their most expensive ATC speaker.
I need a SOTA loudspeaker to test my amps and preamps. The load line of the SASHA is easier than the WATT1 that is replaces. I am using my 'baby amp' to drive them at the moment, with no problem.
However, on practical grounds, for TV, I will return to my Sequerra Met 7's, an easy load and good sounding too!
The money is in the CABINET, more than the drivers. They are HEAVY and are more like solid rocks than wood.
The article 'Are op amps really linear' sounds like the title I cited.

Difference in a domestic environment is that the (cheap) fan battery would drive one up the wall. (the class A part in your post is also incorrect, imo)
On the other hand, nowadays I'm frequently facing aircon noise levels, makes me wonder why the market for silent cooling isn't larger.
That the loudspeaker upper tier is still mainly populated by all-passive designs is interesting. (ATC manufactures a spiffy looking preamp)
Can't design your own SOTA speaker? Wilson is NOT SOTA not by a long shot.
Yes Wilson can't design a speaker without it having absurdly low and reactive impedance. Doesn't say much for the designer but then their speakers are targeted towards the aging , well off, gullible audiophool.
Building your own well braced dead cabinet isn't all that hard.
John may be aging, but I wouldn't call him "well off." 😀 Over the years, Wilson has used notch filters to target driver resonances, and that causes impedance dips which suggest the use of high current amps- I wouldn't use tubes with them. That's a valid design approach, if not one that you (or I, for that matter) would take.
More of concern to me would be the polar pattern. Nonetheless, I've heard some of their speakers in setups that sounded pretty good, though it apparently takes a lot of work on positioning and sometimes room treatments.

I've used several notch filters in my xovers but have made sure to avoid those kinds of impedance problems. If a notch alone drops the impedance too much, I've found there usually are some other xover components that can be tweaked to minimize the impedance drop yet allow a notch filter to obtain the desired notch response, or perhaps use a series notch filter instead of a shunt notch filter.
Well, David, I have designed SOTA speakers in the past, but no more. NOW, I use speakers designed by others. It takes a rather different set of design skills to design a world class loudspeaker, and it is not my best attribute. I have designed speakers that measured well, yet sounded marginally lousy, so I gave up.
Dave Wilson makes a GREAT SPEAKER CABINET, more than anything else. I have been using Wilson speakers for the last 25 years, and I will continue until my demise.
Of course, these speakers are a free gift to me from Dave, for my efforts to design electronics for his recording company, 30 years ago. I designed a 30 ips 1/2" analog mastering recorder and microphone electronics for his recordings, and now he has come to realize that I gave him something really special (according to him), and as I stated back, that if I am in charge of the whole project, I never compromise (and it pays off).
What do you do, David?

Or we could just call a lie a lie like we used to do before we decided that the liars were not getting a fair chance in life because there is no truth , Its your truth and my truth. Well now, we may get to see: "Mommy is that a real tank?" No honey its a monster cable"

I haven't found anybody willing to let me open up their ATC amps so I have to go by what is published by ATC and by reviewers.
The 'loudspeaker upper tier' is only populated by passive designs in the audiophool scene, the same people who buy after-market power cords.
When it comes to professional main monitors well over 90% used are active.
What strikes me about this is that except for classical music those recording engineers are practically the only ones who get to compare the original to what comes out of the speakers and they practically all choose actives.
Some mastering engineers use passives but none of their work ever stuck out to me as being particularly good. The ones that did stick out were mastered on active PMC BB5s using Bryston amps.
As for fan noise my MC2 amps are fan-cooled but they are so quiet that it is only audible when no music plays.
I have come across pro amps with noisy fans like the cheaper QSC offerings but they are nothing like ATC or MC2 amps on any level.
