As you can remember, I had lots of issues with very loud pops and crackles when the computer turned on, when Windows loaded, when Windows went to sleep, when the computer turned off, etc.
Since I installed the Mosconi 6to8 they are all gone. I still have a very feint popping noise when the Amps turn on, but I would call it a normal initialization pop. I only notice it when I wait for it specifically.
I still have a bit of ground noise, but its much less than with the Bitone or H701. Still working on that anyway. I have a few things I can try to get rid of it completely.
Grats on your completion!
