It is a shame when we cannot give our opinions and experiences regarding what we can taste or hear, without nagging back-talk. Why people can contribute their experiences so easily in a 12 step group is because 'back-talk' is prohibited. Then each individual can give their version of happenings in their life, without being shut down and compromised by: 'The trouble with you is.' 'Oh sure!' ' Liar!' etc that prevails here.
I have spent a lifetime studying audio and I have relatively little on a material basis to show for it. Yet I continue, because it interests me, and I can make just enough to get by to live a relatively quiet life. The only thing that I have gotten from audio design is the satisfaction from all around the world that I have designed something special, once in a while, and certain individuals appreciate it, even if the design is more than 25 years old, and there will be no more made in future.
When I listen to audio designs, and their component parts, I take my, and others findings, very seriously. Then the people, who do better than me, financially, ask me for my studied opinion on what to use. Every IC op amp, resistor type, cap, wire, and connector gets studied by me, before it goes into equipment that I am associated with.
Usually, this results in a pretty good sounding product, this determined by listeners who I barely know, and published in their journals.
Now when it comes down to sighted prejudice, what do I care IF I use an AD797 or an OPA1611, when the following amp is going to be an OPA2134? Really, what difference does it make to me? Yet my ears show me differences. This is what I can't ignore, IF I am to remain a consultant who's suggestions usually work.
Right now, I am working with Ed Simon on selecting a cheap 1% resistor for general purpose use. Ed is the man of the moment, BECAUSE he actually samples and MEASURES resistors, and notes the differences. I hope that we select the right brand and type, but I KNOW that I am better off than picking the cheapest or most convenient resistor from the closest catalog. That's what many other engineers do. Sometimes it works for them, sometimes not. I like the chances of success tilted in my favor.

Coke ran lots and lots of controlled sensory testsThey definitely want original coca-cola tastes different from others!
It is interesting if an amp designer wants the amps he design sound different or the idea is to create most accurate amp and one day they all sound the same.

Pulse power only and about 1.6gHz bandwidth. Continuous rating are very low by comparison to the 833.
It is likely transistors will make the bandwidth someday as use of 5gHz small signal devices occurs everyday. It is just a matter of time but for now the Ft goes to the tube. Other than mostly Nautel, high frequency power amps are tubes or magnetron or the like. Small signal devices are catching up fast though. And my only point was the ease with which very stable circuits may be made with wideband devices and nothing else. It is just a device like an FET, BJT, or tube. Simply a device with certain features and limitations. No more or less than that.
No, it doesn't. Tubes don't work like semiconductors with regard to gain/bandwidth. Those pesky laws of physics again...

I would be quite willing to put myself to the test on this one. For amusement's sake, if nothing else.
But I would insist on certain conditions that might get me kicked out of the test before it started. They would be:
Probably more than anyone cares to do, but I'd do it. Could be educational.
But I would insist on certain conditions that might get me kicked out of the test before it started. They would be:
- Establish what is meant by "high input impedance, low output impedance, flat response, low distortion, and low noise." Put some numbers on that.
- Condition 1 being met, I would choose the amps (I want to measure them).
- I get to choose or at least approve the speakers
- I get to choose most of the tracks listened to.
Probably more than anyone cares to do, but I'd do it. Could be educational.
It seems they do. I read of studies of listener's reactions to
"audio illusions and paradoxes" apparently showing that
different listeners will be fooled in a different way, correlated
to where they came from, more specifically to their mother's
regional accent.
As I recall, this is from Diana Deutch's published work, and
lends credence to "west coast" vs "east coast" sound, not
to mention the preferences of our Japanese friends.

looks like a better thread than many for holding side arguments over device limits
I've pointed to these a few times when speed in PA output devices was mentioned:
http://www.ixysrf.com/pdf/switch_mode/IXZ210N50L.pdf
faster really requires ditching the TO-220/247 package parasitics in semis
now wether these mosfets would enable a "Superior sounding" audio amp...

I once sat at the bench next to a tuner tech who asked philosophically: "Why should any of this stuff work at all anyhow?"
With amplifiers, its like you start out with this distortion matrix, and the music signal is a guy with a bunch of beers strapped onto him. He battles his way through the matrix and the if he emerges with most of the suds intact--he is welcomed. If he spills most of it on the way, he emerges as your mother-in-law.
Good evening,

Well, you could always do that next time you're down Texas-way. You'll have to provide any amps I don't happen to have on hand and you'll have to use my crappy speakers. So that might disqualify my living room, despite your total freedom to choose the music and the intoxicants.😀
"Entendons-nous comme les asiatiques?" - non,
In Linguistics, a major problem for learners of new languages is that they attempt to apply the phonology (sound patterns) of their native language to the language being learned - hence foreign accents. They need to throw away all preconceptions and learn to think like a native speaker - virtually impossible after the age of 12 or so...

Indeed. And according to the work of Tadanobu Kakuta, asians and westerners process different parts of speech in different parts of the brain. That can lead to different perceptions of music.
SY. OK, I'm game. I doubt you have crappy speakers, tho. No, let me restate that. You probably do, but also have some good ones.
If I can identify amps by sound when I'm sober, does it count?

OK, Tirebiter...
When I loved on the boat we had "The Club". To join you had to fall in the water getting on or off your boat. It did not count it you were sober. That may have influenced the rest of my life....

Apparently that is borne out in this informal study. College-age listeners prefer the sound of MP3-encoded music to the same music played from the original CD:

I used to read "Audio Magazine" in the 70's. As a collection maybe that was the "collection of most idiotic" writings...maybe.
This was great stuff, we talked about the KLH/AR sound vs JBL, etc. 40yr. ago. Don't forget the KEF/B&W sound.
GOOD IDEA, amp designer can add delay, reverb & metal effect
so the tester can feel the big difference between two amps
Btw we must ask Peter Aczel first, are they sure they changed the amp
for the last blind testing, sometime we can forget the most important thing
