Don't believe everything they tell you

It must be true, I read it on the internet.

I was reading a Lampizator thread here on WBF and one of the links lead me to this article:

http://lampizator.eu/HERESY/heresy.html

I was wondering what the WBF membership thinks about these so-called "myths".

Not worth the time I spent reading it. Most of the time it manages to make very simple thinks look confusing. If people did not know before reading they will not understand what is really happening. Most of these "myths"can "truths" in certain cases by reasons that are not even referred.

And unfortunately the author does not resist to insult people who disagree with him. As always, YMMV.

Yep Micro, and we can add another "myth" to the list, viz that GG beats everything out there.
If I was sappy enough to take everything the Lampi fanboys say at face value, I'd be crying tears of hurt every time I listen to my non-Lampi digital.
Hey, put it in the list! LOL

Most of what he says is true. However, the article is more of a show-off sometimes, and may unnecessarily confuse people . Example:

> The so called "signal" does not flow along some PATH...The circuit response is everywhere at the same time, all elements at the same time. No flow. Input receives - output responds. At the same moment.

Yes, we know. "Signal path" does not mean flow, we all know what we mean by "signal path"

A couple of things could have been said better. For example:

> Amplifiers, what they effectively do, is REDUCE the output impedance of the output device. So they increase the current available at small impedance loads.

True, but I would have instead said: amplifiers' goal is to modulate the DC voltage of their power supplies to match the input waveform as best as possible, and MAY offer higher output voltage and/or current, but they can also reduce the input voltage [and give examples]

> The signal (current) enters via RCA jack, and the first thing it sees is usually a parallel resistor or some kind of parallel pot. The signal sinks to the ground through this resistor and that's all. Yes. The journey is over.

I think a more accurate depiction is: PART of the signal sinks to ground.

Now that's a weird way of thinking about electronics. Not technically wrong if you use his frame of reference. But almost incomprehensible to most humans.

But there is also humor:

> This voltage is then being "read" by the grid electrode of the tube, or in non-hifi units - the base of transistor

Well, except he seems to think capacitors can't power electronics... and he doesn't seem to understand all the physics of speakers and spikes.

It's fairly incomprehensible to people that should know what he is talking about. And a lot of it isn't described well, or correctly. Some bits are merely opinion.

No.1 - Signal path - I agree, a myth.

No.2 - Amplification - nonsense. He's forgotten about crest factor, a very basic error.

No.3 - tweeters use less power, not less current. That's why tweeters have small VCs. Tweeter wire is thin so as not to invoke skin effect which makes the resistance rise with frequency.

No.4 - looks correct to me, a corollary of no.1 about signal path.

No.5 - looks correct, there are no digital signals, only digital interpretations of analog signals.
