Sorry but his videos are not good. Moreover, the biggest issue in them is the sub integration. There is a massive hole in the midbass, on all the videos he had released, and the bass comes from subs that can especially on his Magda Tagliaferro ERC (solo piano) be identified are in different parts of the room separate from the speaker. He took off all his videos except for the New World, which usually has excellent weight and bass, but not in his video. His videos have decent midrange in a very small midrange frequency range.
Most of the music he played on these, like the Haitto Chaconne, New World, Tagliaferro, the Mahler, and many others, I have heard better on videos on much cheaper systems, smaller speakers, and analog using Garrard, SPU, Holbo (used under 5k with the arm). Not to mention that his system in videos does not remotely sound like the Kondo Bionor videos, or David's Bionor videos you released, or even the videos of the same Eurodyn that David had put up. This is possibly because the baffle works differently in different rooms.
I have nothing against supporting the trial for a change in system, but it would be better if his friends showed friendship by saying he is still setting things up, rather than claim these videos are anywhere remotely good. I also hope people who do not like his videos do not in any way think these are representative of vintage or SETs horns.
I used to love his videos with the Cessaro.
