People are asking for the upgrade for reliability, not sound quality.Does it worth? Do this increase the music enjoyment in a double blind test?
(Honest question, thanks in advance for your answer)

Any cap not in the signal path probably will have next-to-no impact if any on the output signal. It's more a reliability thing. Chinese caps are not known to stand up especially well under high ripple current (especially at higher frequency), high heat conditions... some American capacitors can be kinda janky too (ask any guitar amp tech about IC./Illinois electrolytics, we'll pretty much all say "they're bad").
The glue is there to inhibit ringing from components (see: coil whine) and as mechanical support for larger components to remove stress on solder joints. That's an entirely different thing from individual component quality. It's likely they chose the particular value of the caps needed and let the factory make the choice of what exact caps they use - which is why we see some Hypex power supplies with Su'scon, some with Aishi, etc etc.Thanks.
I guessed that, and Apollon confirmed with proper detailed explanation.
I trust the engineers at Hypex and Apollon that know the subject (which cap and where) respect to esoteric audiophilers DIY that upgrade caps/resistors with resonating names just for the sake of aestetic praising the perfomance gain of a cables that cost more than an amplifier...and end up listening to music in small rooms without any attention to reflection or bass management.
looking at the amount of glue I believe the reliability of the power supply has been carefully addressed.

Thank you Amir, got it.People are asking for the upgrade for reliability, not sound quality.

Video is on my Todo list but seemingly I never get to it. Thanks anyway.When you’ll post a video? I believe many would appreciate listening to you.

The caps on our linear regulator board are Nichicon MUSE.
In a 24/7 configuration 5.000 hours is just 6 months and 20.000 hours less than 2 1/2 years. That would mean that it would be impossible to use class D amplifiers in an installation which is always powered on. Can this really be true?If I’m very honest with a cap upgrade the amp measures and sounds the same as with stock caps. The main difference is that the SAMHWA caps which are stock on most Hypex modules have a lifespan of around 5.000 hours and the Rubycon or Nichicon caps that we use have a lifespan of around 20.000 hours.

It's complicated.
Oh.... that's at rated temperature. If I'm not mistaken.In a 24/7 configuration 5.000 hours is just 6 months and 20.000 hours less than 2 1/2 years. That would mean that it would be impossible to use class D amplifiers in an installation which is always powered on. Can this really be true?
The part where 3000-hour caps from a bad brand die faster than 2000-hour caps from a good brand?
Personally I consider the 3000 hour 105C (or whatever temp) rating as the guaranteed one that I can hold the maker accountable for. The estimated values are for reference only.
Clearly you have made the choice to use high quality components on your supporting boards. The same cannot be said however about the main components, the Hypex modules. There is zero excuse for not specifying tier one capacitors on either the SMPS or the amplifier boards. They are marketed as SOTA and TOTL modules, and yet they implement components you and I both know exhibit a poor overall life and are subject to premature failure.
Basically, they are taking their customers for fools and that does not sit well with me, considering the thousands of failed capacitors I have pulled out of relatively recent gear bearing those brand names over the years.
Had a somber development earlier this morning. No amount of money is going to remedy that so not going to ask you for any donations with this review.
