@onhwy61 - I have. Several. In fact, the second video for which I showed the stats in the OP was a trendier and more modern video, actually a song set to a soft rap beat. I was hoping to catch a younger more diverse audience with that, but I didn’t as you can see from the stats. 50% of all the traffic to that video came from external audiophile forums, Facebook high-end groups etc. And with the internal YouTube traffic, the ’audiophile’ theme dominated the search terms used to find the video in YT search, and the videos chosen automatically by YT from which to suggest it to new viewers.
So it’s the same basic set of stats for two very different vids. As soon as you mention ’audiophile’ or ’high-end audio’, all the old blokes come out to play. It’s always been our problem, connecting with the younger crowds, and with women, but in the past we’ve somehow managed to keep replenishing the pool. Now, it looks like nothing new is coming through...
PS - I think the portable Bluetooth loudspeaker demographic are doing okay, they're not the focus here, but are certainly the present and future.
