I bet that isn't true.

So he is using a solid state amp that he acknowledges isn’t the most neutral in order to demonstrate that it needs calibration to be neutral? My general impression was that he was a better salesman than an IR capturer, but this video smells more like he is a snake oil salesman based on the limited parts I managed to get through.

I also prefer to use valve power amps to make IR’s although it doesn’t matter too much, so long as your method is good. Much easier to verify the results being accurate to the source too as you can easily control the variables.

I can only compare to my experiences with ml sound lab (tube) and york audio (solid state). ml sounds fuller, but york audio is easier to play, like more immidiate. weird

There’s more to it than just solid state vs tube. It very much depends on how they’re made (not just the amp used), and there’s a lot of pitfalls to watch out for. York IR’s are indeed very good, a lot of IR’s IMO aren’t. The most important thing is being able to verify that they give the intended results when being used in the intended way.

It doesn't really matter what you use (solid-state, tube) as long as you capture the actual voltage at the speaker terminals and deconvolve the measured response with the measured voltage.
All our Dyna-Cabs (which people think sound great) are captured using the "Mic + DI" technique using an Axe-Fx III and an old Crown power amp.

I remember being confused when he posted that video. His thoughts are a little scattered, but I don't think he is saying anything about tube vs. analog. IIRC, he's saying calibration is better than no calibration.

Out of interest Cliff, did you ever compare with other poweramps and see what kind of IR's you produce?
(BTW; yes I do think the Dyna-Cabs sound great, and I wish I could put my paid for packs into the Axe3 directly!)

Yes, I tried a few different amps. The results were identical.
I just re watched it and he doesn't say that he's using tube power amps, it's just part of his comparison. I think you're misunderstanding the point of the video.

Or, even easier, just use a power amp with a low enough output impedance that it actually functions as intended: a voltage-controlled voltage source - and feed it with a suitable stimulus signal.
That's just such an amplifier. I've got one of those - a Macro Reference - myself.

My impression is that he's not terribly good at the former and that he doesn't know what he's doing wrt the latter. Doesn't mean he won't occasionally come up with shit that some folks like, but he thinks he knows a whole lot more than he actually does.
Yep. He's a Dunning-Krueger type who doesn't know what he doesn't know. And you can tell him I said that.

Yeah. No offense, but we get this from IR vendors religiously every couple months, where they uncover the secret to perfect IRs... for a small fee.
For those who are unfamiliar with Dunning-Krueger (like me), here is a definition that I looked up that's taken directly from the Encyclopedia Britannica website (in remembrance of pre-AI and pre-internet):
Dunning-Kruger effect, in psychology, a cognitive bias whereby people with limited knowledge or competence in a given intellectual or social domain greatly overestimate their own knowledge or competence in that domain relative to objective criteria or to the performance of their peers or of people in general. According to the researchers for whom it is named, psychologists David Dunning and Justin Kruger, the effect is explained by the fact that the metacognitive ability to recognize deficiencies in one’s own knowledge or competence requires that one possess at least a minimum level of the same kind of knowledge or competence, which those who exhibit the effect have not attained. Because they are unaware of their deficiencies, such people generally assume that they are not deficient, in keeping with the tendency of most people to “choose what they think is the most reasonable and optimal option.” Although not scientifically explored until the late 20th century, the phenomenon is familiar from ordinary life, and it has long been attested in common sayings—e.g., “A little knowledge is a dangerous thing”—and in observations by writers and wits through the ages—e.g., “Ignorance more frequently begets confidence than does knowledge” (Charles Darwin)
Or . . . if I were to translate for us common folk . . .
"He thinks that he knows shit, but he don't. He just don't know what he don't know."

I love shitting on thick cunts as much as the next guy, but Dunning Kruger is most likely nonsense:
And you shouldn't be relying on social sciences to make points anyway, due to the replicability crisis:

The Dunning-Kruger Effect Is Probably Not Real
I want the Dunning-Kruger effect to be real. First described in a seminal 1999 paper by David Dunning and Justin Kruger, this effect has been the darling of journalists who want to explain why dumb people don’t know they’re dumb. There’s even video of a fantastic pastiche of Turandot’s famous...
