no link at all, it just happened to be noticed then (only that I boosted
the levels to reach near fullscale), and I used to have other default
hdspmixer settings.

Sure, that is the reason why I cut the silence away - there you can hear
clear differences.

I totally agree, my B.s drove me almost crazy several times. For
concerts (where I need 3 of them) I always have a spare one reachable.

I did that as well a few weeks ago, and by B. failed :-)
Right now I don't have additional 4kEUR just for reliability, that's why
I still use my B.s (except when I can borrow a Micstasy), but I cannot
wait the day when I say good bye to them...
