the same happend here once.

another one has problems with the phantom power, it is sometimes
(unpredictably) disappearing on some channels, making it unusable for
recording. Gains tend to drift and are hard to adjust. A third one has a
low frequency noise on one channel. The fourth one is fine right now,
although the delay is slightly different to the other three ones (about
0.5ms difference)...

Until now I had no problems with the outputs of the ADA8000.

Recently I made a recording (lute & singing), partly with ADA8000,
partly with RME Micstasy, both with the same Neumann mics, and I could
barely hear the difference...
