How to sell hundreds of hi-end amplifiers.
- a practical 7 rule guide for all the self acclaimed hi-end internet gurus out there
-----------------------------------------------------------------------------------------
Q: Hello!
Where do you buy your speaker's drivers?
Where are they from?
A: My drivers are all custom built and
carefully designed with hours and hours of deep listening tests.
Translatates to:
I bougth this lot of fullrange professional PA drivers for cheap,
and now I'm trying to make money with them.
Aside from the "no nfb" claims,
the best way to identify a hi-end guru is asking if his drivers are custom made.
If he says "yes" you can be sure he's an hi-end guru.
Hi-end audio is all about the "chain" concept:
you make your amplifier to mask your preamplifier defects,
and of course speakers are made to mask amplifier defects.
You want to spend less money on the output transformers in your amplifier?
Just use less iron, no matter if they won't go deeper than 70Hz.
Because your loudspeaker are already incapable of doing better.
And if you ask why:
Q: Sorry,
those speakers can't go deeper than 70Hz.
I don't like them,
I can't listen to rock&roll with them.
A: You can't understand nothing about hi-end audio,
and the fact you're listening to popular rock&roll music proves this fact.
That's not hi-end music.
Translates to:
hi-end music is all the kinds of music
that don't put in evidence hi-end systems defects.

Hi-end loudspeakers.
The best loudspeaker for the hi-end guru of course is the fullrange single driver. Not for some sonic or technical reasons: but because as already said, you can sell 3000$ speakers that have only a single 50$ driver, instead of two 30$ drivers. That's a net 10$ gain.
Of course the best hi-end speaker must have high price (more on prices later). A popular method is to stick a Ciare CH250 (a beautiful 50euro speaker) in some sort of cabinet (of course you have to built it by ear, no calculations are allowed, or you aren't a hi-end guru) and sell it for insane prices.
How many hi-end speakers are built this way?
Go search the net, or go to some hi-end meeting,
you will see many systems with $20 - $50 drivers in them.

A little nuancing is in order. Have a look at these measurements:
Capacitor comparison
Note that this is not about sound quality, just reduction of power supply noise. There is a difference. If this is worth the extra money everybody must decide for themselves.

Interesting, but two questions immediately arise when I read it.
Aren't the black humps to the right in the diagrams rather FFT artifacts than reliable measurements? If so, the claim about performance at and above 20 kHz is void.
In both experiments we see a tendency towards better HF performance for the better caps. But what if we were to rerun the experiments with a bypassing film cap in all cases? Couldn't a cheap cap plus a film cap not be expected to perform as well or better than the expensive caps alone? That would be a cheaper solution.
The bumps are the result of the vertical compression of the graphs, they are not artifacts of the measurement itselft. Have a look at this:
AC supply noise
There is a lot of noise on the AC. As you can see the spectrum is filled with odd harmonics of 50Hz.
The Clio System itself is reliable up to 22KHz, it has a voltage calibration source build in and can fully automically calibrate itself.
That could very well be the case, next time I will also try a bypass film cap. My point is that there is a difference that one can measure.
Gerrit Boers said:
OK, considering that the spectra fall almost to the apparant floor and then makes a hump or two again at higher frequencies, it does look very much like the artifacts one often gets. But if you say the system is reliable also for those frequencies, the humps probably are real data then. Actually, looking back again, I now realize that there are no humps in the last measurement (of the Jensen cap), which might support that the humps are real.
Yes, there obviously are differences between the capacitors. I wasn't argueing with that claim.
I've put up a little page here:
FFT window types
It shows the spectrum of the AC voltage for the heater supply with 6 different window types. Below the measurements is a table of recommendations I found at the National Instruments website.
Perhaps you would like to comment on that.
BTW 'Testing Loudspeakers' is underway 😉
