What has been the experience of those using the ADA 8200 converters concerning reliability? Also, are the ADA 8200 preamps that much better?

I have been thinking of upgrading the ADA 8000 converters on my Saw Studio machine. These are the version that shut down when playback is stopped. Not an issue when using SAC and SAW Studio together but a pain when using SAW Studio alone. I have been considering the ADA 8200 as replacements but I am concerned with reliability after reading a number of reviews.

Also, it seems that Behringer's repair service leaves a lot to be desired. Thanks for your input.
