So I have one of these handy devices. I have Manley snappers and a woo audio headphone amp that I use as a pre. With the device in my system, startups are quieter, and I have a lower noise floor at my speakers. In fact when I kick over my snappers, I wonder if they’re plugged in. My only challenge is that the device seems to lower the gain of my preamp…by a lot. I’ve experimented with this several times, and at one point forgot I had it plugged in and wondered what happened to my gain. Strangely enough, I have it plugged into a sub and it seems to exert a system-wide noise lowering effect as well. More experiments observations to validate this though.
Any thoughts on why my gain would take a dive at the pre?
