As mentioned in my report the videos don't grab the bass and the density of the stage. behind.
That said, I think with videos if it sounds very good, it should be auditioned. If it sounded bad, that was another thing. Most seem to think these videos were good, it is quite obvious in person they will get much more insight. No one should click buy after listening to a video unless it is pocket change for them. But they should expect to enjoy even more in person. And I have my words accompanying what I heard, but I can understand some people will say off with the bottom of the report just leave the words in.
Ron picked up a brilliant passage of play to say wow that sounds real. To my point on the other thread, if you play good passages you can know if it is not real pretty quickly. When someone tells me they need one month to evaluate (set up time not taking into account, in which case even a few months is too less), I wonder what they are listening for. With Britney Spears and Spice Girls you can listen as long as you like and evaluate forever. If with Oistrakh's, Szeryng's, Kogan's or Heifetz's bow one cannot make out how it sounds at least in the violin range, they should just buy sorting on the sticker price. If it sounds real similarly for other instruments vocals orchestra in a few LPs, beyond that is stress testing.
I think the best thing to do is create downloadable hires PCM files to listen to. A simple ORTF setup of microphones does very well. We tested this in my listening room and also in the Synergistic Research reference room (I designed their recording setup: 2 AKG 414s with a Sounddevices 722).
