No direct answer noted. I'll take that as "yes".
Then what are they customers of?
John this surprised me. I know you don't like digital, so if you haven't been listening to records, then what have you been listening to? Do you still have a lot of tape?
I don't understand the question. I don't sell anything. But my interest is with robotics and programming. I have got many project offers related to this but I don't have enough time due to my day job (the clients have offices too, they are off when my day job is off). I have opened robotics classes which I did after my day job, but it's so tiring. I prefer doing my you know what 😀 (capacitor rolling
)Hehe I'm not that serious regarding audio business. Just a kind of brain storming for my retirement plans, or if i decided to quit my day job.
There is nothing mysterious about proper pcb layout or rf shielding, just look inside anything that has high speed digital signals or rf circuitry.
Engineers know about this stuff.

The truth doesn't really matter. Certain people here appear to be willing to go to any length, including endorsing the work of a total nut, just to prove a point.
No jokes about guinea pigs please, they did all they could do in helping to enhance our understanding of the hearing apparatus...... 🙂

As you had recently shown that your interest in the truth isn't that great (when issuing ad hominem attacks without evidence), maybe you shouldn't complain.....
@ Evenharmonics,
clear answers to your questions about "business relations" do not help.
I answered your according question already clearly in 2015 and it does not stop you asking that question again and again (you'll certainly remember doing it in this thread after 2015) always with the attitude as if a hidden "evil" fact would be revealed.
Come on, billshurv, mmerrill99 is only doing a bit of mirroring the often used tactic where just the personal belief justifies to demonize any business relation as the solely reason for published opinions.
Happened even when I quoted from Bech/Zacharov's "Perceptual Evaluations" book about the difficulties doing propper sensory testing over at another forum where the members claim to be interested in a scientific approach.
"Sure they say that, they want to sell a book"......
Given that I'm sure, that you get why it is indeed funny that a bunch of loudspeaker guys is cited emphasizing the utmost importance of the loudspeaker. 🙂
Btw, I'm sure that you've got a lot more information about Tiefenbrunn's actions than me (don't had access to british hifi press at that time) but in Germany in the beginning of the 80s the usual routine in "hifi shops" to demonstrate loudspeakers was a wall of loudspeaker along a wall using a pult to switch the amplifier output from speaker to speaker.
Customers usually choosed (after quite short listening, but still after switching in all available in the choosen price range) the speaker with the highest tweeter level. Cerman "taunus sound" was often a winner in that situation,but you could bet that it was only bearable at home (for prolonged listening) if placed behind the drapes.
So, I don't know if Tiefenbrunn invented the idea but Linn's promotion of the single speaker demonstration was clearly a good idea.
You might be wright about his turntables (which imo have had a ridiculous price rallye), but the "garbage in, garbage out" approach has its merits.
Couldn't he have done same with speakers instead of turntables?
So maybe it was more a matter of conviction?! (smart marketing surely,though)

Ah, yes, this wouldn't be a vintage Jakob post without twisting my previous words into your envisioned meaning.
Minimizing RF emissions is a science. Reasonable people expect anyone providing such a service to provide before and after measurements. This is what happens with non-audio EMC consultants. If you want to take advice from David Schulte - who proves his ignorance on virtually every page of his website - then maybe you should invest in a tinfoil hat because 5G cellular is surely going to give you cancer.
If I might ask, what is your purpose here? I will 100% admit that I am not the most prolific contributor of open-source designs for the community, but I try to give design tips or share knowledge where I have relevant experience. I've looked through your post history briefly and I can't really find anything you do besides do the exact things you criticize others of, along with possibly furthering some hidden agenda by throwing out strawmen, intentionally confounding arguments, or references to flawed studies.
The SNR of this thread was never good, but it's probably reached an all-time low now that it's become the mmerrill99 and Jakob2 clown show.
With that, I realize that I have been unhelpful in returning this thread to discussing electronics instead of religion, so I'm out until this gets back to a reasonable topic.

What amuses me, is merrill's display that he doesn't even understand the physics of sound.
Don't take it literally, as it is imo just a game to show how easy it is by mimicking the typical FUD narrativ of "evil hidden" business interests.
I'm sure you've noticed this kind of "reasoning" (where strong personal belief is sufficient reason for any kind of allegation) already in posts from (maybe? 🙂 )....Evenharmonics?
@ chris719,
as you're obviously doubling down by doing the same again, I'd say it supports my argument........... 😉

I had a good laugh when Billshurv cited Tool's use of £22K Revel speakers with .....wait for it..... $20K Levinson monoblocks - that's $40K according to him
Of course amps are of no real importance - all properly designed ones have been transparent for 40 years or more, right? Remember his argument is that speaker/room are the only remaining issues in audio 😀
So Toole, instead of buying a reasonably priced 'transparent' amp that will drive the Revels, he has fallen for some Levinson marketing spiel & parted from his $40K instead of a couple of K - hilarious 🙄
The phrase springs to mind, "Given enough rope .............." 😛
Watch while he tries to backtrack & justify this (he already started saying there was a discount involved - hehe)

As usual it depends; I know around a dozen personally and additionally my impression stems from published messages in mags and internet forums.
Usually it follows from probability considerations that it is quite unlikely having met and read (about) only the small group of outsiders while the overwhelming majority used professional monitor loudspeakers at home.
But I admit that no survey (afair) is the basis of my "a lot of". 🙂
I don't understand your argument, as these are surely not the only contenders to choose from?!
Of course "professional monitor speaker" is not a thoroughly defined term, but afaik the price range for powered speakers intended to be used in a production environment (and delivering a decent minimum quality) starts around 200 $/ pc.
Of course,not to forget the "down the hallway" test, but that is related to the production process but not the home usage, or am I mistaken?
Most of that list have PhDs and are/were approaching this from the point of view of improving the listening experience (at various price points). The fact that they all converged on speakers as being the most important part is interesting and I feel especially Toole has a refreshingly pragmatic approach. Also he publishes. There is no secret sauce with him.
Wall of speakers is bad. More than one pair in a room may be pushing it too far IMO. Wall of speakers setups were relagated to bargain bucket stores by the time I started buying hifi so I cannot confirm if he started this trend or just championed it.
He did make a line speakers from the LS3/5a Klone 'Kan' to the Isobarik. I can only assume more profit on TT parts so he would tell you to buy the cheaper speakers and upgrade his turntable first. Many people in uk followed his mantra. He was almost like a prototype Steve Jobs in that respect!
I am not sure the UK market has recovered from the combined onslaught of Ivor and Julian (Naim). As a teenager I was more interested in what was coming out of the USA, but I was young and easily led!
