What's the big deal?
It's exactly the same as claiming that a different "plastic" in an exact same value capacitor can be heard.
Or silver wire instead of copper wire in a transformer.

His only sin is that he charges too little and he didn't have "Sublime Intergalactic Audio Magazine" write a glowing review.

Different 'plastics' or dielectrics in exact the same value capacitors can lead to measurable differences, so no snake oil here.

What about CD? Perfect sound forever! The ultimate scam perpetrated by Phillips and Sony! Assisted by Herbert von Karajan...."All else is gaslight!" yeah right.

I would not brink cd here as I think the thread is about audio hoaxers...
btw, you have to realize cd is more than 20 years old, and that is pretty good in ever changing world of audio, when it was conceived, it was pretty radical, I think, and still can play quite well...well it took us 20 years to tweak the DA converters to sound right and once you replace the myriad of pesky opamp on the output with tube, the sound is just fine
do you know any other media like that? (what happened to SACD, DVD audio, HDCD, minidisk, DCCs and others...)

The Altmann "Tube-o-lator" lacquer

This is already in the snake oil thread. It is my favorite snake oil reference there.

There are convincing testimonials. What I don't see are objective explanations. I guess it tubolates the transistor.

They did not teach us anything about this in engineering school.

And this is true. Reference Bateman's work.

What never gets discussed is that if you use the right capacitor in the right application, even the lowly electrolytic introduces virtually no distortion. Conversely, you can configure an electrolytic so it introduces significant distortion. This is why you can use an electrolytic as a coupling capacitor, but not as part of an RC filter circuit. (Actually you can and I have seen it in commercial equipment, but it becomes a significant source of distortion in such an application.)
 
Think this discussion is in the wrong section... more like a Lounge discussion, definitely not Solid State...??

Except that the guy is now selling this stuff to paint onto transistors.

The Altmann Tube-o-lator lacquer is an overtone-filter coating-compound for plastic semiconductor packages.
The ALTMANN “TUBE-O-LATOR" lacquer is applied only on the top surface of plastic semiconductor packages of AD-converter-chips, DA-converter-chips, OP-amps and discrete transistors.
...
Important: Always coat the complete top surface of a device. Do not partially coat a surface, else you may end up in a mess of non-correlated overtones, and the result will not sound as intended.
...
Attention: Experience has shown, that power transistors in certain circuit topologies CAN over-react to Altmann “Tube-o-lator" lacquer. Over-reaction will lead to a dumb sound (that will make you feel sick), because too many overtones are filtered.
 
Imo, it is still Lounge material, no matter what he sells his paint to paint onto.

But as you are the royal high decider, Lord SY, I bow to your expertise and wisdom.

Let the games begin!!

PS. I only put the magic oil, I mean paint, on my feedback loop and the bottom of my chassis. The chassis treatment adds gravitas.
