Dunno, but the new model is also scalloped braced, so my experiences
with Martins tell me I should prefer the plain-braced older one. But
really, because individual Martins vary quite a lot in tone, I would
have to try specific examples side-by-side.
FWIW, from the recordings I've heard, the CEO-7, a Gibson L-00 knockoff,
is an absolute killer, and that is scallop-braced. Maybe I like
scalloped braces on small bodies and plain braces on big ones.
