the EIN is the primary number I look for to select what I need, but then
other details are important as well. Unfortunately most of them are not
expressed in the specifications and need testing. I mean the cleanliness of
sound, the real frequency response and anti-aliasing filters, the shape of
the background noise above 20 kHz.
which presonus interface are you talking about ?

Thanks John and Gianni,
I'm looking at the Presonus Audiobox 44VSL
<http://www.presonus.com/products/AudioBox-44VSL/techspecs> which says an
EIN of 133 dB, 20 kHz BW, max gain, Rs=40Ω, A-wtd . I'm weighing that
between my current Apogee Duet
<http://www.apogeedigital.com/support/duet-firewire> (128dB @60dB gain 150
Ohm), Sound Devices USBpre2
<http://www.sounddevices.com/products/portable-audio-tools/usbpre2/specs>
(127db),
and RME Babyface Pro <http://babyface.rme-audio.de/> (unknown).
The Presonus has the best EIN, but it is the cheapest of the bunch, which
is what makes me curious!

it appears very interesting, however the AudioBox 44VSL can't be USB bus
powered. The 22VSL can.
another ADC I think attractive for the small size and the 192k rate is the
ZOOM UAC-2, but its EIN is 125 !!!

Note that the Presonus EIN was measured at an unusually low Rs of 40 Ohms and
with A-weighting filter. This results in a significantly lower EIN number
compared to the other models that were measured at the commonly used source
impedance of 150 Ohms and without A-weighting. So, the Presonus is NOT better
than the competitors. It is obviously just a marketing trick...
See also the specifications of the Sound Device 7xx recorders that list the
EIN values at different measurement conditions:
