I noticed this too. It doesn't feel as wet/liquid as before or the original. Sound like blocking distortion or something like that. The Blue Chanel is amazing in this FW.Now that I played it all day, pretty much everything except 5153100W RED sounds great. This one however sounds looser and muddier than before.(According to my older Presets) Maybe it sounds closer to original thing and I liked the fw15.01 version better.
