30 would be a very reasonable number. And they were matching number stereo kits.
I offered them my preamps to study, and the recorders (Grace V3, SD 722, Edirol R44). They claimed it as their issue, and didn't want to look to see if it were my gear misfiring. With that said, I could never get my gear to do anything untowards that would be damaging.
With all of this said, I was a major league DPA fanboy, and still am; I love the sound.
DPA, O.B. Sorenson, and Bruce Myer were wonderful to work with through it. They had my back, and with each issue, I had gear at the ready that they'd send. They were very supportive of my recordings at the time, which were in larger part, more baroque and renaissance.
Its water under the bridge at this point; though it was really frustrating. What I still have a hard time with is, why me?
