It been said that there are no absolute truths. Just workable truths, and relatative truths. In this regard, there is no "absolute sound", just (very) subjective references to high fidelity and high(er) fidelity.
There is no absolute truth...Common place fact ...
But here once this is said you forgot acoustics when refering to high fidelity stereo system... Doing so instead of refering to controllable objective acoustics parameters and concepts and experience you refer as all marketing to the gear itself as the "source", the material design of a gear piece and his associated price tag...This is "not even wrong"... It is beside the point and put in our head by consumers marketing...
If someone want to know what is acoustics experience in stereo system , the owner manual of the best high end gear in the world is worthless..
Read an acoustician , the last genius to know what he spoke about is Edgar Choueiri .... Acoustics with an (s) is not mere room acoustic...
The gear does not determine the level of acoustic satisfaction , his rightful implementation in a House/room/ears-brain does it ...
Incredible the point to which publicity about the gear brainwashed us all ...
I will not give other example of brainwashing... I will be out of subject...
The only way to go through audiophile experience is learning how to do it not purchasing costlier materials and accusing me or others to be envious of high end ...😊 It is the opposite i pity those who buy high end very costlier product and use them in a non dedicated room bragging about gear...
Gear matter it is a common place fact ... But it is completely secondary compared to all acoustics and psychoacoustics paramaters and concepts...
Period.
Forget the gear and study acoustics a bit...
or call me envious of 100,000 bucks speakers as some just did ...😁 It is ludicrous... I am proud of my speakers low cost modifications and my acoustics controls at no cost yes...Audiophile experience for peanuts is possible sorry for those who dare to claim for the sake or their expanse that it is not possible ... It is...With vintage gear or basically well optimized low cost good gear...
Or perhaps even if i tuned my room i am deaf to high end ... 😋
