I have a Venus concert grand that is over 30 years old and has held up very well structurally. It has a very good tone. The upper octaves have a nice ring to them, which is probably helped by the fact that I use nylon strings in the 2d octave and above, and I can play well with aggressive or soft attacks in the high range. The tension is a bit lighter than other pedal harps I’ve played, which I find very good for fast arpeggios, trills, and harmonics. Like many harps that play easily, it can be overplayed in the middle register if you try to force it. I can rip away in the bass and higher ranges, however, and produce a sweet, resonant tone in the middle range without straining. Upper octave right hand space is pretty good. Not as good as a Camac, but better than many harps and you can actually play up there.
