You are there vs. They are there

@spenav ”How would you know the recording is changed unless you were at the recording studio or the live venue”

l would never know. I was talking about “if” a system did not actually reproduce the intended information or adds its own signature it is not true to the original.
 

“There is a difference in adding things or restoring things that were actually lost” 

I’m not sure if the “adding things” you refer to is in agreement with me or not, but the restoring things that ARE “actually lost” l am not sure is possible. The only way l would think you are talking about is maybe an extra recording element (or track that was part of the master) that has been recently rediscovered but was never included in the original mix?

An example that springs to mind of a lost, or in this case a rediscovered element is the 2.0 unlimited release of the soundtrack to “The Omega Man”  When the original first issue “limited edition” was released by Film Score Monthly 15 years earlier, it was not known that a third (centre) track of the keyboards/Synthesisers existed. The keyboards, a key (pun intended) important part of the score were quietly there on the original CD, but only recorded by the far left and right track microphones. Restoring the integral middle centre microphone elements with the higher keyboard levels brought the original soundstage ambiance back to that which was intended.

I believe we are in agreement. I feel like we are a little too hang up on the fidelity part of Hi-Fi. It’s like trying to pick a faithful painting portrait of Abe Lincoln but we have never seen him in real life. It will be hard to know which one resembles him the most. Obviously, some of them would be rejected off hand: like Abe with dog ears or with a chicken beak or Abe with a tail. But there would be a fair number of portraits that would be plausible. Which one is true to the original would be hard to determine. At the end of the day, we will have to pick the one that pleases us the most. Because we are dealing with music reproduction and music as an art, we have to allow ourselves some freedom to choose based on preference to our ears even though we might stray from the supposed original. We also have to keep in mind, that our rooms have a lot to say about the presentation. Take care.

Well that settles that!

@spenav Exactly. Why should we hang ourselves up over this false notion we must adhere to some unknown reference. Now I can accept we have reference for things like timbre with acoustic instrument, but sound stage/presentations. Do whatever is pleasing to you.

Seems the best one can do is to optimize speaker placement and then hope for great results in "They are here"  and/or "You are there"
