Hi Sara,
I play a Camac Atlantide Prestige, 47 string harp, and the “Blue” series are almost identical to the Prestige, (and the 44-string Clios) except that the Blue harps have the electric pickups added. I have had experience playing the Mini Blue 44 as well as the other Blues, and they all are fabulous harps. The ones with straight soundboards do not have quite the “presence” of the ones with extended soundboards, when just played accoustically. But once you are “plugged in,” I cannot tell much of a difference. Back to your question, the Camac Mini Blue 44 had much more presence to me than the Salvi Daphne 40 had, playing accoustically. You would have to have a pickup system installed in the Daphne to compare it to the Mini Blue, when amplified.
I hope this is of some help to you. I would prefer the Mini Blue over the Daphne 40, especially with four more strings on the Blue!
Harp Hugs,
Balfour (and Carol Lynn)
