Well, I thought the purpose of laser trimming was to eliminate the DC offset but more knowledgeable people than I (that means the rest of you guys) could correct me. In any case, the offset should only be a few mv (<10) without trimming and almost all the newer opamps are trimmed.Have you discussed it with Rod Elliott to see why the problem exists?
BTW I have toyed with the idea of changing the OPA2134s but have never gotten around to it. Can you really hear a difference between the AD826 and OPA2134. At this point in my life I have reached audio nirvana as I can barely hear my wife in the background when I am listening. I think that is what is meant by a "blacker background" because when I get done with my listening sessions, there seems to be a dark cloud in the room :).
BTW since you seem to be headed toward a JFET DIY have you given thought to making it balanced rather than single- ended?
