The fact is NO one knows why hi-res sounds better. NO one knows why vinyl can sound better. The time domain theory is just that -- a theory.Interesting post....The science behind conversion is complex...
But when we listen the music in our room, my point is there is many more powerful factors to improve de sound than the switching of digital to vinyl or vice versa...Anyway the 2 have their own limitations and flaws....
Vibrations and resonance controls, decreasing the noise floor not only of the audio system but of our house, the passive materials treatment and active non electronical control of the acoustic of the room, all these are way more powerful change in S.Q. than the comparison between a very good dac and a very good turntable....
But it seems people are fixate on the less important choices that divide us instead of the more important factors that can create a better high fi experience with ANy audio system, digital or vinyl, and that can unite us...
A last word: for me the apex of audio experience is natural instrumental timbre perception and imaging... A turntable can make it and a dac can make it.... But the 2 will make it even greater if the mechanical,electrical, and acoustical embeddings dimension of the audio system is treated and controlled.... All the rest is relative to taste or habit at best, or useless at worst.... :)
Happy new Year and thanks for your post....
