I have played a lyon and Healy lever harp, and a camac lever harp. I don’t know what model the camac was, the L&H was a prelude.
I completely preffered the Camac! The tone was so much more clean and clear than I thought it could be. L&H obviously prefer pedal harps (and I haven’t played any other pedals to compare it with, but I think the sound can’t be beat) , I’m pretty sure they make lever harps just because… You need to have a few lever models too. Camac has their DHC series, which are electric lever harps, so I believe they’ve worked on the quality of their lever harps more. Now that is merely conjecture.
Also you can’t know a harp until you play it. I live in south Florida, so I’m reeeeeally far away from most harp makers. I ordered my 85petite pedal on blind faith from my teacher. I have dream harps I want (Salzedo, Princess Sakura, etc) but my little beauty doesn’t disappoint me. I recently purchased a carbon fiber Delight lever, and I adore it’s sound and portability! Shop around and find what works for you. (If you want portable, nothing beats a heartland harp!)
In my humble opinion, go camac for a lever, L&H for a pedal, and either harp you would love for life!
