Hello Cladane,
The noise of this electronic system is low enough (I checked using the Focal Utopia headphone), and by security there are 4 jack outputs with attenuator and 4 direct outputs.

That is interesting. I haven't seen that device before. I would not be so happy doing that long term though, 20v into a HP will blow it up and permanently damage your hearing as well. Unless there is some form of limiter or step down transformer. I am using the Metrum Aurix to our my LCD4s. The amp is very simple, really a impedance corrector with most of the circuit designed to protect the HPs.

Of course max power into the headphone (and hearing) would be too too much via the direct output, so the volume as to be kept quite low, which is not a problem. This is the case for most amplifiers anyway.
There are also 4 outputs with built-in attenuators. These make a strong protection.

This amplifier is not vastly more expensive than a Viva Audio 845 headphone amplifier for example.

Interesting. But doesn't the HP output need to be low (50 ohms HPs) or high (200+ ohms) to drive those HPs correctly without FR shift? Or does the pot sat between the HP and the amp outputs do that?

The amplifier is already loaded by power resistors (of the correct impedance) in the jack adapter box.

"A new youth movement is energizing the high-end audio market"

https://www.cnet.com/news/the-new-youth-movement-in-high-end-audio/
Thanks for sharing. I agree, it is great to see how many young and small innovative audio companies are alive and well!

On the older and some bigger companies it is a bit more worrying. Many are in decline, and most have been bought by investment banks or big fish who thrash the name to death, loose the energy and direction of the original owner etc. I hope this new energy keep going. High end audio is niche, some is affordable, but a lot is heading north to footballer prices IMO.

I bet a lot of guys on this forum have bought (supported) quite a few of these younger companies, so hopefully the future of high end audio is also in the younger bracket of clients as well.
