Good to see you again Merc. Go back and read my post. Mine had hiss before, to the point where I turned my amps down to about 3/4 gain to compensate. Now the amps are all the way up and hiss is nonexistant at loud listening levels, even when within about 6 inches of the tweeter during quiet passages. I have only had it for 2 days, and it is still smoothing out (as I said in the earlier post, I never really thought electronics needed to "break in", but now I have changed my mind). It is very transparent. More
so with the new "blue Dot" because the hiss is gone.
Soundhound must have opened his up because he says the new parts are considerably more "heavy duty" and likens them to parts you find in pro equipment. All I know is that the fix worked for me, and I don't believe my problem was based on speaker efficiency. If anything, my amp may not have been a good match.
