Well, I happen to think our test is sound, but I could be biased.=20
;-)

But I will say that follows the guidelines set forth by others
who have made the same measurements.  In any case, I am always
open to suggestions for changes.

Yes, the spectral test is a relatively new one, added as a result
of these discussions (and those on other lists).

Neither the MP nor the Mark V review showed any indication of
a problem with this, but it may be the review rigs never put an
S9 + 20 signal into someone else's receiver during the reviews.

No critical judgement was rendered for the Field because what
is considered to be good or bad has yet to be cast in stone
(and there are very few measurements of other rigs to serve as
reference points).

However, you can be sure that we are keeping a close eye on this
issue as a whole.
