I hope you took-it with all the humour inside ;-)No insult intended. How else should I identify people interested in audio that may not work in the field as their primary occupation?
For me, audiophiles are people that spend their time to listen (and show) their systems. Changing endlessly their gears, reading poetic comments in audiophile revues and magazines, buying the last AD converter with tubes glowing inside that promised heaven, strange and expensive cables, magic cones, special connectors in wood, you know.
You can recognize them easely looking at their discotheque: all the money they put in their system, they don't use-it to buy records.
Anyway, I often thought that it would be better for them to buy anti depressants pills ;-)
This is a good opportunity to lighten the mood, or is it? A little video that I've posted elsewhere for the benefit of audio mystics YouTubeFor me, audiophiles are people that spend their time to listen (and show) their systems.

They will most likely have a copy of Also sprach Zarathustra on Deutsche grammophon and Kind of Blue by Miles Davis......... And perhaps a few other must have releasesYou can recognize them easely looking at their discotheque: all the money they put in their system, they don't use-it to buy records.
Audiophiles are people who like to play with and listen to hi fi. If they were 'autophiles' then they would like to play with and drive their cars, and they, like audiophiles, would find special test sections of roads where they could test their favorite car with a stimulating drive.
IF they were 'winophiles' (silly word but consistent with my topic here) they would try new and interesting wines, and sometimes even pay an almost outrageous sum just to try something considered extra quality, just like audiophiles might try a new piece of audio playback equipment. Some might even be amateur winemakers, so they subscribe to 'diy wino' or something like that. '-)
At the same time I can see a whole lot of my 'critics' here attacking 'autophiles' or 'winophiles' in much the same way as audiophiles are attacked here.
You know: 'Far to expensive', 'impractical', 'let me see the measurements to prove its superiority', 'it's all a marketing hoax', etc, etc. What a damper you guys would be at the Porsche or BMW website. I wonder if they would allow you to continue to contribute?
Or all wines taste essentially the same, double blind tests have proven it so. Therefore, any wine more expensive than 'two buck chuck' is a waste of money, and proves your subjective gullibility. Even I don't believe this is appropriate.
Why attack others, rather than learn from them, especially the people who try new ideas, rather than stay with the old, tired ones?

The wine and food analogies fall apart, the different choices are an analog to choice of recordings or performances. The equipment would be glassware, plates, etc. a subject with its own silly dialog. We don't listen to equipment it's the content that matters.
Are these scopes good enough to qualify as an $80 TEK scope? '-)
The descriptions of those items almost guarantees DOA.
Some interesting food and wine info:

None of these analogies make much sense to me, the different food, wines, cars are like the music, that is what has the flavour or character or smoothness or power. The recordings and audio equipment is just a convenience. If the food is not quite to your liking season with a little EQ, distortion or compander(tion) it will make it sound "different" too
Now when it comes to scopes, perhaps the cheapest 465 on E-bay might have a few problems, but all of you guys are super 'repair engineers' aren't you? You should be able to fix any problem from parts in your junk box. Too lazy? Then maybe pay $50 more for a working one.
This thread is generally at the point where I was at 40 years ago, when I did my research and implemented a number of successful pro and consumer audio designs already. However, I have learned a good deal of subtle detail, (like scraping the leads of passive components before insertion), and many other subtle techniques and decisions that make a good product into a great product, but I am just not able to discuss them fully here, not because I need to hide them from my competitors, (that may have been useful 40 years ago, but now I am an old man) but because my suggestions will be attacked immediately, because their effects are not necessarily easily measured. Some are, like DA and slow power diode switching, but they are dismissed as impossible to hear or to effect the sound in any way.
Pass said he likes slow diode bridges. I don't consider anything like that taboo. Diodes can tune the sound of some devices pretty easily. But if you think you can't talk about that stuff, but you can talk about Bybees? I don't follow. What do you really have to lose? A few more haters? You're not doing anything right if you don't have at least 1 hater.
Power cables are more diffcult. The only way I managed to keep RF out reliably is using significant amount of ferrites (common mode) and a shielded sub-enclosure for the AC input containing all dirty stuff (inlet with filter, switch, fuse, etc) and using feedtrough capacitors on the lines entering the main chassis, with the ferrites being the last components before the feedthroughs and mounted very close to those. Even better yet is a sub-enclosure for the whole power supply following the same principle.
RF current clamps are your friend to see what's really going on on your cables, both outside and inside the chassis.
Meh. Ferrites almost always sound bad. I prefer common mode chokes and the Schurter DENO. The capacitors are a double edged sword, they can enhance noise too, so just piling them on all over isn't wise. There are wrong ways to do it, and right ways. I'm almost certain JC's fancy phono preamp has this problem - and he doesn't care.
Really ? I cannot imagine-you doing this ;-)
What kind of effect did you expected ?
May-be to can simplify the use of your vacuum cleaner ?
This said, if they are beautiful (I have no idea what they look like) why not ?
Maybe the question is, what kind of floor does Wurcer have? If it is a wood floor, well...
Then I would suggest look beyond the audio bandwidth until you find a difference you can measure and see if that could be the reason you hear a difference.
Wise words. The effects of RF are astounding. Take these grounding boxes for example. They are literally antennas tuned for certain RF, and are enhanced by a parasitic affect between components where the proximity makes a larger antenna (inside they have separate copper shapes that don't touch). I've seen measurements of them in the audio band and the conclusion was "they don't do anything at all". But the same measurement out of the audio band shows a clear spike in RF. RF elongates the signal, and enhances very low level stuff in the signal. This is a well known thing in the audiophile world.
There is a caveat though, most things beyond the audio band can be measured if they affect the audio band. The problem is they appear innocuous since you can't really be sure it is there.
Of course.
But let-me give an example. i prefer to use cat6 network cables for signal cables. i will not make measurements to compare them to other cables. I know I will see no difference in the audio bandwidth. But I can hear a difference, .
CAT 6 can be one of 3 types, UTP, FTP or STP. And there are sub-sections within that. Which one are you talking about?
Ok, if you think 'mistaken' (believing things which are not true) or 'ignorant' (not believing things which are true) mean the same as "stupid" (having low intellectual ability) then I can't help you.ridikas said:DF96, it doesn't have to be the actual word stupid, but it's all the same. If someone around here claims to listen (imagine that on an audio forum) and hear a difference that cannot be measured on a $85 Tektronix, they are immediately ridiculed and receive condescending responses.
Yes. Nice to be able to agree with you.Tournesol said:What surprize-me is that most of the "audiophile" cables, sold in the market at an incredible price do not succeed at this simple examination ;-)
So far it looks more like trolling.ridikas said:I'm playing a bit of Devil's Advocate here to make certain points and get a conversation goin, but I think that's fair.
The problem with 'listening' is that most people do this with their eyes open and their prejudices fully switched on, especially when they believe that this is not the case.
I generally use the word "audiophile" to mean those who would often run a mile from genuine hi-fi (which is intended for faithful reproduction of music) because they prefer to listen to their equipment. Real hi-fi cannot be listened to because it doesn't have a sound; you just hear the music. The clue is in the name: an audiophile loves audio systems, whereas a music lover loves music.john curl said:Audiophiles are people who like to play with and listen to hi fi.
All the designers that I know and have worked with try to make the most ACCURATE and TRANSPARENT audio equipment that they can make. We don't even have tone controls on most of our equipment.
It is OK to love music through your portable player, but it is not very ACCURATE REPRODUCTION, and I am surprised that you even think it possible.

Last night I listened to a digital transcription of a popular weekly FM music program that had lots of acoustic instruments. It was so good, that I put on my larger system to hear it better. The sound difference was apparent, but it would not be worth the added cost, unless you really liked the challenge of audio reproduction. It would be like the difference between my Acura and my Porsche. For normal stuff the Acura is more convenient, but the Porsche is more stimulating, so long as the road allows it. To go to the grocery store, it would absurd to drive the Porsche. For a Sunday drive the Acura would be rather boring.

Excellent post John. Your work and ideas have inspired me and countless engineers throughout the world. Don't ever stop teaching and sharing your thoughts whatever they might be. There's an entire new generation that's looking up to you. I'd like to think that the negative vocal are just a few. History won't remember them.
Not sure who this remark is addressed to. Clearly not me, because I never mentioned portable players.john curl said:It is OK to love music through your portable player, but it is not very ACCURATE REPRODUCTION, and I am surprised that you even think it possible.
