The OP question is valid and interesting...
Most reviewers even honest one are sellers...
The Youtube agon reviewer the OP cited is probably honest, but he sells his "expertise" in agon and youtube...
about ultra high end gear ....
Then using hyperboles is, if not legitimate, easy to understand...
it is interesting to listen to him because who spoke about 100,000 bucks dac anyaway?
No one ... 😊
my dac value was 20 bucks...Its real value is 500 bucks...
i am lucky yes...
Those of you who read my post will realize that I did none of these things. What I did was call attention to a youtube site that -- I am claiming, with evidence -- tends toward hyperbole in their titles.
If this post gets taken down, then I think only one conclusion can be drawn about what has happened to "moderation" here.
i think the OP is right...
This site banned one of my friend. because of the pression of some seller working here probably...
It is anything but a free forum for sure, it is a commercial place...
By the way the whole point of my presence here is : "audiophile experience for the poor"...This is the title of my virtual system page 8 years ago...
I try to educate people about acoustic as the way to hi-fi, not 100,000 bucks dac...it was my journey to experiment with acoustic...
This is why i side with the OP on these questions ....Sellers inform but ONLY to sells more...
No sellers ever said that acoustic method means more for sound than upgrade of gear...NEVER.... Save sellers of acoustic panels who anyway sells costly materials not acoustic experiments and acoustic control anyway...
Sellers sells...
Those who dare to experiment inform without too heavy prejudices....
Anyway sellers put their skin in the game of selling, those who experiment put their skin in the game of sound quality improvement at low cost...
