Hi Dennis,
I own the Catalina Deluxe and play on the Celtic owned by a friend at weekly sessions. The Catalina is more comfortable for taller people, and the stave back really makes the harp comfortable. Bubinga wood really helps with tone which, to me, is of utmost importance. It is important to note that no two harps sound the same. Two Catalinas built exactly the same will have two different sounds. If you are able, try out a harp before you buy it, and don’t buy a harp that doesn’t move you inside. The abalone and other acoutrements are nice….but in the end…it’s the sound that matters..
