I have to tell you that hearing it is great, but holding it and feeling it live and dance in my fingers as I breathe and talk is quite the most wonderful thing I've ever experienced as a craftsman. It is of another order again from anything I've felt- and I've felt quite a few over twenty years.
With a really fine instrument, I can feel it moving around in my fingers while I talk, and the way that it does that will tell my little brain about different qualities that are present, or more likely not present. Most instruments will respond to my voice, as filtered through my fingers. This one responds to my breath. Jumps to my breath.
Of course it has had centuries of training by wonderful musicians, including the present one. And it has had the benefit of centuries of diligent and maybe inspired maintenance (and possibly, modification) by the worlds most talented repairers. But it all adds up to one of the most superb artefacts (in my humble opinion) ever created by a person, because it is not only a sublimely beautiful physical object, it is itself a very active participator in the re-creation of a magical level of musical performance.
Gaby Lester is a charming and very talented musician who gives generously of her craft and skill. Her web site is here, and it includes lots of interesting links, including one to the beautiful Italian village of Fossa that was devastated by earthquake but struggles to reassert itself, and a You Tube video of her playing a tune with 'The Who' and lots of other wonderful stuff. It was a joy to meet her and to spend a little time with her wonderful instrument.
