Redwoodgarden, I think you meant 2002, not 2000. Agreed that this could not be a "good sign" for Dunlavy fans or audiophiles in general, but the fact doesn't carry any implications with it about the sound of past Dunlavy products like Dazzdax's speakers.
Psychicanimal, C-J's service and quality control have been exemplary in my experience. The incident you relate could be due to a number of possible circumstances, maybe connected to the service visit, maybe not, but I wouldn't assume that C-J won't take the responsibility if they are to blame. Either way, I don't see how: A) One anecdotal episode (and not one with a final resolution as far as you tell it) could let you know that a company is having "issues"; B) This story of yours has any bearing on Dazzdax's situation or the sound of C-J pre's in general. What could your motive be in throwing out such an accusation?
