Added a third Purple to my system, this time in my PS Audio DirectStream DAC replacing an Orange. My system is sounding better than ever, however I also violated the one change at a time rule and added 3M RFI absorber material in strategic places at the same time.
I'm guessing that much of the improvement is from the fuse, but that's just a guess. Since you have to open the DAC to get to the fuse (and it's a PITA), I opted to do both mods at the same time.
Happy camper, though only 24+ hours in...
