That's great news, as I had the same idea! I'm very much interested in your impressions and if possible, can you include some pics from the process? If it sounds great, I'll probably opt for the same mod. P.S. What pads are you using? I've heard that Focus pads (original Focus, not Focus-A) do a bit to tame the highs on the HE-400.
