I’ve played what is probably the student version of the Angelica, and will be renting it as of tomorrow (super excited about that, by the way!). It is, in my opinion, a lovely harp, though it has only 40 strings (I’m not sure about this, as I haven’t counted them). The sound is beautiful and mellow, at least in my ears, but it isn’t very loud, so I don’t think it would be good for concerts without an amplifier. “My” harp is quite old, but I have no idea how old (from the seventies maybe, my teacher suggested), so I can’t speak for newer Angelicas. I don’t think Salvi makes them anymore? They’re not on the website.
I hope this helps!
