Even a new Salvi I heard recently. It had a wonderful sound, much like a Lyon and Healy harp, until the harpists tried to play louder than a mezzo-forte. It just didn’t go with them. It stopped resonating beyond that point so the fortes had their sound choked off. In contrast, a Lyon and Healy 85 on the same program had a nasal, French quality, but resonated freely at all volumes, and filled the room easily, especially at forte. The tone of the Salvi was nicer, but only good for playing at home as a result. I would think it was because they are heavier, with thicker columns and necks, and that’s what impedes their resonance. That’s what I’ve always been told. The contrast was surprising, but so clear.
