I am also musically connected (went to Oberlin conservatory as a pianist, and since settled/married into the Toronto music scene) and also own the De Capo. It was the only speaker, in my lengthy auditions in both Toronto and NYC, that sounded like music.
That said, I LOVE your system. I have been thinking about VTL myself--amplification is my current weak point. I've just purchased the GamuT CD-1, which (based on my impressions at the latest Montreal show) is similar to the Audio Aero players (I formerly owned a Prima) in its emphasis on music over mouse-fart detail.
I quite agree that exposure to live music is the only way to understand what a system is doing correctly and what it isn't. Better yet--get a recording of a concert you attended. There's nothing quite so humbling.
