couldn't be happier with all of them.
picked up the m10 about 3 weeks ago, and was happily surprised by the internals. the ca-14's have exceeded my expectations as well, very high fidelity and balanced.
just did some recording with the blondies, and these too sound very good but require full p48 and higher gain than the others.
the blondies and the ca-14's may even be a bit redundant, they seem similar. maybe the ca-14's have a brighter top end?
i need to test them against each other to get some more information. though i was running the ca's through the ca-ugly and the blondies through a littlebox. 71db of gain in a tiny portable with full phantom and a single 9v -- great box.
... and to boot all of this is recording a fairly crappy upright piano in a small room.
off to the hat store next week to buy a styrofoam dummy head. i wonder if a large honeydew and some epoxy could do the trick
