Teo, I believe the "fundamental flaw" you are talking about is Quantization Error. This is the error that occurs when a voltage falls in between the smallest digital values. The ADC then has to round the voltage off to the nearest value. These errors are dithered into noise. The signal to noise ratio of a 24 bit ADC is 120dB! That is seriously quieter than any signal you are going to get off a record, by at least a factor of 2. In other words, vinyl's "fundimental flaws" are a lot worse than digital's. Brick wall to what? Once any information is recorded permanently in any format it is "Brick Walled." You can not add or subtract anything from either format. You have to repeat the performance.
If you like the sound of vinyl better then just say it. Nothing to be ashamed of. But coming up with absurd explanations just does not cut it.
I have an old copy of the Byrd's Turn Turn Turn. It is a bit noisy to say the least. I digitized it and put a copy on my hard drive. I make like I'm playing the record but in reality the input selector is on the hard drive which I surreptitiously cue up at the same time as the record. One friend in particular was floored when he discovered it was the computer. With volumes matched nobody can tell the difference reliably.
It is not the format which determines sound quality. It is the way the recording and mastering were managed. If you love music throwing all your eggs in one basket is cutting off your nose to spite your face.
