No subjective impressions,
the tube amp measure far worse so how can it sound better?
Please, explain.
There’s no question ‘high end’ is all about stuff that looks good in designer living rooms, or stacked up with huge speakers and amps and has little ultimately to do with state of the art performance. AP systems have been around for 20+ yrs and allow any one serious about building high performance gear to do just that - and nowadays there’s some fantastic software for use with sound cards that does almost the same, but we still get very bad equipment masquerading as something special and SOTA.
I took one of my amps down to a dealer here about 2 yrs ago. It’s 240 W per channel and would meet with the approval of most here. It uses a lot of SMD and is as a result very compact (19” wide by 19 deep by 6” high). The showroom was full of high end gear (big B&W, lots of US speakers, Magico’s etc) and every amp was the size of a large microwave oven and I don’t think any sold for less than 20 grand. After they had it for a week, they told me it was awesome sounding and plenty powerful, but they wanted something ‘more expensive’.

I already explained by using bold font to point out the parts of your posts that are in subjective impression domain.
Hmm, looks like at least two of these threads have been locked:

High end!!?? I have mounted loudspeakers 170' in the air. I have boosted high frequency response flat to 12,000 hertz at 200' throws.
Now if I close mic a band and reproduce it through loudspeakers that hold their response curve to 20,000 hertz is that an accurate replica of a live performance?

Bonny,
I have one product we build inhouse for $20. The competitive version sells for $100. In user tests mine works much better. So I sell mine for $120. Only problem is I don't sell enough of them.
Not surprisingly price affects perception of value. The low cost model we offered at $50 was perceived as not as good. Do I have to tell you what the difference was in construction?

Mine is not cheap either. But it looks functional and is built like a brick sh1thouse.
Unfortunately, it’s more a form follows function thing and less a piece of art.

Some like distortion - but it aint reality. Nothing wrong with that.
For some, distortion seem to be able to fix other faults in a system, it seems like. Nothing wrong with that if one like this way to build a system.
If one manages to build areally low distorsion system and find it that it sounds dull or off or whatever... I bet it is FR that is the problem.

The more I mess around with my stuff, the more I'm convinced that FR is the problem. Conversely, the more I fix the FR, the less I feel the need to mess around with my stuff. 🙂
CERN boffins zap antimatter with ultraviolet lasers in the hope of revealing the secret symmetry of the universe • The Register
I wonder if this used the magic containment units JN and his team were hogging from billet unobtanium?

^ Bill, they had the PI from the antimatter cooling work on either the "Science" or "Nature" podcast (draw whatever conclusions you want about me), and he said at one point, "I don't have hope, I'm an experimentalist" -- which meant something a bit different in the context of the interview, but is hilarious out of context. 🙂
*The question was more about hoping to validate some set of theories or understand why our universe went to matter rather than antimatter immediately after the big bang.

I have great admiration for experimental physicists working at the bleeding edge. They help spend enourmous budgets and know that 99% of the time the conclusion of all the work will be 'I need a bigger machine'. The Stoicism is strong in them. (Although I do recall a geneticist who spend over a decade looking at the wrong chromasome).
The LIGO team told me they wanted to 10X the length of the detectors, besides the earth's curvature the 100B budget was a problem. Surprisingly both LIGO sites came to 1B together.
Yes, it is. But that is sooo last generation, old news for me😉. The next generation confinement bottle has already been wound and completed. Roughly a factor of four more complex than the one the article cites.
Right now, we are working out the vacuum leaks. Seems a vendor had a brazing issue. We are fixing that... Then the unit will ship to CERN.
The best part is, we were able to get the physicist in that group to actually create the wiring path software to control my winding machine, to plant the wire where it was needed. Now, three physicists can create magnets for my machine. My replacement is just about to join that club. And, we're just about to finalize PO's for a control system to upgrade the windows 95 platform..
Alas, poor "visual basic".....I knew him well...
It is fun seeing the new guy use two forward slashes to try to comment text in VB (//) instead of (').
But, I must admit....he is picking up everything far faster than I did. my fallback argument is....he has a good teacher...😱
That's my story, and I'm sticking to it...

ps..while they do acknowledge my employer in the "credits" for making the bottle, I don't exist... at least for the first magnet, they did credit me... the exact wording was..."photo courtesy of." Sigh, I am known only for my ability to push a button on a camera...luckily, something a monkey can do....actually, did

We passed that exit miles ago (24 years ago). When the first bottle was being made, there were two competing collaborations attempting to confine antimatter. Because of that, all the advances we made could not be published, as that would involve exposing IP of the ALPHA project (known as ATHENA back then). We also have a few IP "edges" as well, so we wanted to keep the tech close to the vest so we would be the go-to guys for these types of projects.
Ours made full power first time it was turned on. The other group spent 4 years trying to get their magnet to even work, they really could have used our advice.
The Nat. Labs tended to not fund stuff that didn't have an immediate budget, there was no mechanism to allow us to continue advancement, so we had to rely on being the only place on the planet that could do it in order to get any work on the machines. The difficulty is letting the machine sit idle for a year or two, then getting back to it, looking at the code, and wondering who wrote it???
Now, we are scrambling to update the tech using materials from this millenia, and running code that is current. The next project will require lots of objects, over the next 10 years give or take, so we are already late..

Ed would be interested...I just picked up a pin gage set, .251 through .500 M2 (inches). As I learn this machining stuff, I find the biggest concern is not really the machining/tools, but measurement. If you can't measure it, you can't improve it. Now I have sets from .011 to .500, in increments of .001 inch.
My mechanical tech friend says to put a masking tape flag on the smaller pins, as they can go away far too quickly. I always listen to him.
I'm still in disbelief that Amazon does free shipping, the gage set wasn't light..

Bought new!!! Chinese stuff!!! Garage sale stuff from a deceased machinist is the better way. Have to remember to post a picture of some calipers found that way.
Of course now you can check the magnet gap before you recone a loudspeaker.
Now you can prove a 1/4" pin will not fit in a 1/4" hole! (There is a reason why if you drill a hole with a 1/4" bit and carefully measure it, you will find it is actually over size! Of course a 1/4" bolt is also undersized.)
Also you now no longer have a reason to buy a centerless grinder!
Let me know when you get the granite table, precision level and straight edge.
Oh slightly off topic, any version of a frequency reference often called an atomic clock....
Remember the guy who dies with the most toys, wins!
Added humor, I was checking hole sizes just yesterday. (Couldn't find the drawing!!)
