It really should not matter whether the poster says if he or she played the music.
Especially since in the case the poster asked us to focus on the quality of the sound (pianos) and not the player.


I guess the poster did this so as not to have the topic stray away from the topic of the quality of the sound.

He probably did not want to hear “this is good playing” or “this is bad playing” or "how did you play this". He probably wanted comments about the quality of the sound.

In this case knowing whether it was the poster or another person playing does and should not in any way affect your judgment of the quality of the sound.

Now don’t get me wrong, it is always good to say who is playing and where the file came from, but is not necessary in a small forum like this and is absolutely not necessary for us to make an evaluation of the sound (like what the poster wanted us to do in this case).
