Seems to be a bit of a specs war going on. Often the improvement
isn't in the product but the measurement capability. Test equip and
setups have their own noise floors. I know the NF measures of our sat
transceivers improves quite a bit in the RF anechoic chamber.

Which audiofire model uses a cirrus DAC? I don't see the DAC
reference in their spec summary and none of dynamic range specs
are close to above
and the comments here on the recorder quality is a bit disturbing.

That's not an AudioFire, and I don't see a DAC reference. This is
Audiofire: http://echoaudio.com
I have the Audiofire 12. Echo use AKM
converters in the bus powered units, and Cirrus where AC is available. In
this review,
http://www.soundonsound.com/sos/oct05/articles/echoaudiofire.htm
, the
Audiofire 12 beat out a Layla 1212M, which presumably uses what were then
AKM's best converters, with better s/n. I'm not pu****ng Cirrus, but it was
an interesting opinion.
The converters in the Audiofire 12 are actually bidirectional codecs, so
you
wouldn't want to try to match part numbers.
