Hello Manuel!
Well I too heard the VSM SE's at Christophe's, and loved them when paired with the Air Tight. The Transcendent did shift their tonal balance towards the leaner presentation you mention, always refined but also lacking flesh for me.
I blame that on the association with this amplifier and not on the speakers themselves, which really shook my world with the Air Tight and led me into buying them ultimately!
Whether you'll like them in the end is another matter, but what you heard with the Transcendent doesn't reflect, IMHO and in Christophe's system, what they are capable of. Also, Christophe moved from a great front end to a much more analytical one that I personnally didn't like (I told him so) and just added to that problem.
Say hi to Chris for me! Let's grab a coffee soon.
Best,
Jean-Baptiste
