Hi Aaron--
Apologies for the subject line change. Good find. Being able to see
the state of the batteries is also a nice addition.
The unit seems of special interest to people with low-noise phantom
powerred mics and non-phantom recorders or recorders with poorly
performing phantom circuits. Some of the later seem to have been
introduced to the market. The first question that jumps to my mind is
how does one know if the $200 cost difference is better invested in a
2Phant or perhaps towards better mics?
If I assume that the performance of the phantom supply in the Sound
Devices 722 is among the best in terms of noise performance, one way
to start this evaluation is to compare:
NT1-A-> PB224-> 722 (Phantom Off)
and
NT1-A->722 (Phantom On)
which I've done several times with consistent results. One of them is
at the head of this test:

I'm cc-ing this to Eric Benjamin who is testing the PB224 along with
the WL-93 and other mics in case he has comment.
