I'm sure that many of you know what I'm talking about. I had it in my bart preamp and now I hear it in my audere preamp. It's a high-end zing that seems to always exist. Maybe it's just a given with any preamp... just the way that these things work, but I'd love to get rid of it. The thing that I love about my passive G&L is that there is no zing. Of course, the tonal options are more limited, but there is a baseline quiet to it that I like. Any thoughts?
