Mahgister, you are entitled to think that doing all that stuff to a DAC will make it sound better but that is psychological and solely in your own world. The only way you can make a DAC sound different is by dumping it in the bathtub. However with a turntable all you have to do is increase the VTF a little. There are all sorts of things you can do to a turntable to change its sonic characteristics. Getting a turntable to sing separates the men from the boys. Anybody can get a DAC to play even millercarbon:-)))
Any piece of gear is always an ideal GENERIC design with measured and verified theoretical capabilities, but any piece of gear, to produce a sound or to contribute to produce a sound, must be implemented in a SPECIFIC environment, which will be each time different... This is the reason why reviews have only anecdotal meanings...
A dac like a turntable will sound differently if the mechanical, electrical, amd acoustical embeddings are controlled OR not...
A dac can be isolated mechanically like a turntable, his metal box can be coupled/decoupled in the right way or not, the electric field around the arm of a turntable like the electromagnetic field around the dac can be act upon , and no vinyl on a turntable will be perceived in the same way in different room like any speakers.... You cannot review a dac or a turntable in the same way with the same results in different conditions...
When you throw a dac in a bathtub you change his GENERIC capabilities by introducing it in a new SPECIFIC environtment.... This is drastic change.... The modifications of the 3 embeddings controls do the same BUT in a controlled and subtle way and the dac can continuously work...It cannot in a bathtub....
And by the way spare me the "placebo" accusation....😁 You know better....I hope you know better anyway....🤔
The psychological placebo effect dont work in the same way in audio and in the case when you give unbeknown to someone a pill of sugar, his spirit being directly linked to the body the sugar pill can do miracles because the link between brain and body is a complete unity...
But in audio cumulative materials modifications in an incremental way with an increase in positive S.Q. for many years, after hundred of experiments with my homemade devices, cannot be reduce to be "placebo" only and mainly, because the link between my brain and the perception of sound is MEDIATED in a complex way by different material working dimensions (mechanical, electrical and acoustical) and is NOT direct link like in the case of the spirit and the body.... Miracles are possible in medecine not so much in audio...Except in the nutcase people ready for asylum , and i hope you will exclude me from this case....
Getting an audio system to sing is what really " separate the man from the boys" by the way, anybody can tweak a turntable even you .... But to embed rightfully and to win on all S.Q. counts the many elements of an audio system, working on the vibrations and resonance problems, and decresing the noise floor of the system and of the house because they are coupled together indeed, and implementing a complete sets of acoustical passive and active (non electronical) controls in the room acoustic, all that for peanuts money,mthis is what i call separate man and from boys....
Anybody with enough money can buy some S.Q. buying good electronical devices, but audio begins after that... Not anybody can with peanuts money changing the three embeddings and create an audiophile experience.... I succeed... Call it placebo if it is your only argument and if this contribute to your peace of mind.... 😊 And i dont doubt that you can tweak your turntable without placebo effect in play....Anybody can do that by the way... But almost all people own an under working audio system, not knowing how to embed it especially at no cost....
I wish you the best and Merry Christmas 😌
