"I don't understand the resistance of some against this commonsense reference. After all, it's the original recording, processed through the same YouTube path as the system video."
If we are going to compare videos and submit a reference, I would suggest a video of a live performance such as the one below. Others seem to want a YouTube file for reference against which they compare people's shared system videos. A live system in a room recorded and then processed through YouTube, if the system owner uses live music as his reference, should be compared to live music recorded and then processed through YouTube, in my opinion.
The only problem is then how do you compare this to totally different recordings if you only play Analog?
I see a kinda confused discussion over the last few pages. Surely others will argue with that.
I ask myself what is the purpose of an in-room system video and to what should it be compared.
Imo, the in-room recording of a stereo playing a piece of music is to give an idea of how that system sounds. (Yes, yes, we know it is processed/played through Youtube, but that is a leveling field for any video played through Youtube, making it a non-factor.) So you have a recording of a stereo. As such it can be used in a variety of ways. People will use or abuse it how they choose.
When I started making videos of my stereo I had two goals: a) capture my system's sound at a certain point in time with its then configuration, and b) share it with friends to give me feedback on how they assess it and make suggestions if they have those. That, to me, is the primary value of an in-room system video.
What I found over time is that my friends and I did the above and we also shared in-room videos of our systems playing the same record. That proved a fun and useful exercise as we share a common vision on the type of both sound and music that we like and we share a common reference for assessing our systems against. That became a significant part of the value equation -- that is also why we did this.
Now once a video is made public, via Youtube or WTF, it becomes available for others to do with it what they choose. One thing others do is change the nature of the comparison by putting an end-user's in-room system video against other videos that are not in-room recordings of stereo systems. Some go so far to claim the not in-room recording is a reference.
I reject the notion that a not-in room recording has value to me relative to my own system. Such a recording may sound different, it may sound 'better'. I'm not interested in comparing the
sound of differently made recordings (sometimes of unknown provenance) but rather comparing similarly made recordings. I reject the notion of a not-in-room recording -- a speaker-less recording -- as a reference. My reference is the sound of live acoustic music, not a recording.
