Michael--
I'm not aware of poor line input quality being a wholesale
phenomenon. It would be a true set-back in audio standards as this
wasn't the case in cassette decks 20 years ago.
If we find that others confirm Dan's finding of low frequency noise
in the line input when used with external pre and mic with known
low-noise noise performance, then it does create cause for more
general suspicion about line input noise performance. But the LS-10
might also turn out to be the only exception too. A large reason
that we can make reliable recommendations because we can use our
collective resources until we get consistent results. Stay tuned. Rob
