Worser yet..Unproven "Technology" that doesn’t exist through objective means...but keeps magically appearing. Only marketing fluff with no way to prove efficacy by any type of real science or engineering.
Your affirmation are only a free belief about something you dont know...
My system is 500 bucks ...
I bought no tweaks... I created my own homemade devices at no cost and replicate at no cost some very costly one... I even invented one very powerful myself...A mechanical equalizer for the room....
Then i KNOW what could work or not by my listening experiments....
What you call a "tweak " with despise, i never bought them...Not because they dont work or never work...
Because it is easy to create your own with basic science and common sense...At low cost or even at NO cost...
I called my devices: controls in the three working embeddings dimensions of ANY audio system: mechanical,electrical and acoustical...
They are NOT secondary addition tweak to a system they are the main working controls tool of the system....
My system dont need any costly upgrade and compare favorably in the ratio S.Q. /price scale with ANYTHING... It is not the better in the absolute,not at all for sure, i am not a fool....But it is one of the best on earth for 500 bucks probably...I listen music with ZERO frustration....
Then be creative, trust your ears, and dont read too much audio reviews....
And let the pretense of science to the scientist.....Or to the sunday "scientism" skeptic club....
Audio is fun , may cost peanuts, and those who think otherwise are deluded and very loose with their money....I am not....
My best regards with apology for my rant....
But many things must be repeated here....
