Thus, in general it appears that listeners made decisions about quality
fairly early in the listening experience (within the first 10-15 seconds)
and did not change their opinions after they listened for extended
periods.

That would entirely depend on what you thought were significant
changes. I saw about what I expected. The most difficult sources
showed the most degredation between long and short-term listening,
with the least changes showing in the 'worst' perceived providers.
But, is 2-6% significant or not?

The authors gave their well-informed opinion.

Keeping in mind that the largest demand for these services will be
voice and voice-over (most unsighted/poorly sighted people of my
acquaintance are quite capable and very adept at operating their own
music systems but cannot read the printed word, of course), and so
including classical and jazz as source materials is something of a red
herring even if interesting.

I don't think so.

Given the very limited dynamic range of
the human voice *while speaking*, nothing in that study is surprising.

Nothing is a big word.

It has been my historical experience that short-term listening (such
as in sales rooms and at first-impression at home) are barely
indicative of long-term results.

Can you report any tests that you have done with care equal to those in the
cited paper?

Unless you do, you're not exactly comparing apples to apples.
