I just measured the iRig Pre this morning as well. I got and EIN of
-112 dBu 20 Hz-20KHz unweighted (-114dBu A-weighted) with input
terminated at 150 ohms. Noise was 3dB better with the input left open. =
Max gain was measured at 23 dB using a complimentary balanced input.
Bandwidth was pretty flat with a cutoff (-3dB) at 90KHz. I only
measured one sample.
I still think that they are a great value. I just bought a case of them
for resale. I will be offering these with an option for a custom output
plug (which will most certainly void the manufacturer's warranty) and
will stock adapters as well.
