I have gotten a few reports of sounding like my audio is muffled as compared to running the K3 alone. It is true that with several listeners in different states, there is not a consensus of opinion on that. Some of the guys think it sounds just fine, and some say they can hear a slight muffled sound with the KPA turned on. The point of comparing it to K3 only and K3 with KPA500 is that the mic is not in the equation. The report is clearly that the amp sounds muffled. Not unreadable, just slightly muffled. I have a bias current of 0.4A...about the only thing I can think of to check. I think there was some discussion of setting the bias current here, but I can't find it again. What is the range of bias current for best linearity? I don't see any help in the manual.
