Cleeds,
I am not sure why you are taking such an adversarial tone. The links you posted really do not discuss this topic, and this is not a conversation about "mastering", which if done differently for the formats, will make them all sound much much different.
This is a discussion about high resolution digital, good quality analog tape, and vinyl and what they are capable of. The link that CD318 posted gets into this, but dig further, and you realize that even though the first post makes it look like an exact comparison, read farther into the thread and it is not (as I posted), not to mention at that time he didn't even want to discuss high res formats due to, at that time, lack of availability. There is little discussion of the playback chain as well.
I never mentioned distortion at all with regards to vinyl. I specifically said "analog processing". That is a critical difference. Again the link that CD318 posted is interesting as Steve says they could tell CD and vinyl apart by listening to the tails on sounds (which does make me question their digital signal chain), and that tape and acetate master sounded the same (to him). I could sit someone down and in about 10-15 minutes teach them how to easily identify vinyl at least with headphones and near-field monitors, based on how the "sound-stage" changes. In normal listening environments because of the interaction of speakers, room, and cross-talk, the effect is not as consistent. Notice I said changes, not better, worse, but different and you don't hear that differences between high res digital and tape.
I am familiar with Mike's tests, and see that you have different results. I know that Mike has very high end equipment, but in the audiophile world, with digital, that could work against the most transparent result. Most high end audiophile companies claim to make products "tuned" for the best sound (to whoever was doing the tuning by ear). There is a difference between technically transparent, and "tuned". If the DAC is "tuned", then it is not a faithful transparent reproduction of the digital capture. This is similar to some high end DACs now having user selectable filters, which all sound a bit different, but without knowing what the original source material sounds like, how do you know which one is most transparent? It's the same with MQA. Claims technical superiority, but is it transparent or tuned?
Cleeds, you saw my posts w.r.t. azimuth tuning on a turntable, and how tonearm pivot effects azimuth with height changes. Should be obvious from those posts I am not a neophyte w.r.t. vinyl. You did, however, make my point with your last line. I never said as a group you are preventing advancing, nor did I say that enjoying LPs was flawed (just the opposite actually). What I said is that blind devotion to a format based on perceived superiority, that may not actually be the case, can prevent you from moving forward. You could call that blind devotion, blind aversion as well. It would be akin to not buying a 2020 Hyundai based on how bad the 1980's vintage Hyundai Excel was.
"The suggestion that those of us enjoying LPs may be "preventing the next
leap" is just absurd. Many of us have made that "leap" and found the
potential of digital is often not realized."
This applies both ways too. There is a lot of blind devotion to Redbook CD capturing all the possible range of human experience.
