Doubtful or false statements from outside diy audio.

On the internet there is, -as you surely know, a lot of false information. The thing is that it is impossible to register to all forums and refute these statements.
In fact, the situation is not that different to the situation that was discribed long ago by J.P. Sartre: you listen to the radio and someone declairs something that you clearly object to. But you don´t have any possibility to reach every other listerner, it is a matter of inequality (now, I hope that I´m not being too political). 😎

My intention is not to hang out any specific person. I´m more interested in how some conceptions evolve and remain.
An example I read today:
"Hmm, I would recommend at least a 400W RMS MOSFET amplifier (I use 600W). MOSFET and Thermionic valve amplifiers sound the same and provide even harmonic distortion. A valve amplifier is heavy and can break more easily (and expensive for 50 year old technology) and sounds the same as a MOSFET, so for a bass guitar, there is no point in looking at valves.

Stay away from bipolar transistor designs, since they tend to clip and give odd harmonic distortion which sounds especially bad on a bass guitar. It is possible to design a bipolar that will clip soft, same as a MOSFET, but you won't know (unless you design it yourself)."
 
Not the Source

The interweb is not the source of misinformation; rather, peoples' minds have been full of misinformation since the time we were able to form ideas. E.g., the earth is flat, beer is bad for you, &c. The interweb just makes it easier for you to be aware of how much misinformation is out there.
 
Even in this forum there is plenty of misinformation. It does not mean malicious intent, just lack of knowledge. On the bright side, the web makes it easy for you to check multiple sources before wasting your time and money.

Caveat lector!

You have to admit, the earth is pretty darn flat....

This strikes me as not a bad overview of the position WRT BASS GUITAR amplifiers for an absolute beginner. It's pretty much nonsense for hi-fi. A lot of misinformation can arise due to taking things out of context.
 
The diyaudio has fanatics who love to build. It is a facet of the human condition that the system I have painstakingly built ALWAYS sounds better than anyone else's. Many subjectivists have not bothered to invest in or build measuring equipment so can only rely on their own brand of boosterist subjective language. The diy forums are pretty sharply divided between these two ideologies. Hi Fi salesmanship and the audio popular press relies on subjectivism and so ultimately you must gather your friends and have an unemotional discussion of the sound of your creations !!!

There is a surprising amount of inaccurate information about electronics, including textbooks. In the past this has led me too a lot of confusion. With growing knowledge I have become increasingly aware of the number of silly mistakes that slip through the net ( possible pun ) and I realize how perplexing it must be for beginners.

With most subjects, even scientific ones like engineering there are different opinions as to the best way to understand something. The problem is that some people write as though their opinion is fact, or at least close to that, this seems to be a common trait in those who are inclined to teach us. A good teacher provides different perspectives and encourages critical thinking, to a certain extent the teacher needs to put their ego aside in order to foster the sense within the learner that they are finding things out for themselves, rather than being dependent on the teacher. Anyway I've went off on a bit of a tangent!!!

The long and short. All things are open to interpretation, some more so than others, though!!
 
My own experience... Shortly after "Information Age" was popularised, I wondered if "Misinformation Age" would be more appropriate. I admittedly never gave it much mind time (Other than... say... a recipe is information, but doesn't stave off anyone's hunger. But let's not go down that road.). I agree with GOR3, but I'm not so sure how modern consequences might affect the equation.
Anyway, enough of that. I'll close by saying that it can be a balancing act... Being authoritative enough to draw attention, trust and believability, while still allowing freedom of thought (necessary for learning IMO, unless it is Pavlov's dog sort of stuff).
Must be tangent day🙂
 
OK, maybe I don't get around as much as some, but the earth is about the flattest object I've ever seen.

gee, rivers flow down hill because the terrain is not ...... ?

Bragging again, hey.

cogi - would you use the term "bucolic" ?
