in the "output" section, you can select the various analog outputs, and the speaker is one of them I believe.
as for how good the a/d section is.
well, its good enough.
for me any way. a/d is my least critical componant. if the signal being fed to the a/d is a good one, then its all good.
i have faith that the ACM will provide a great signal. right now, my 248 is providing signal, and the recordings thus far have been remarkable.
