I’m late to the party but I had a battleship Aurora from 1976 and it was a joy to go to an Apollo and Iris. The Diana is great, too. Highly recommend changing to Vanderbilt anti-tarnish wire and gut strings. Your harp will sound and play even better. If this is a new harp, use a feltbpick to play little glissando bursts on the upper registers. This will help open the sound board and make the tone even. Enjoy your new harp!
