It occurred to me also that this anonymous review may have been posted by a
competitor...

I don't do much SSB operating on my K3, but I was struck by the comments
about splatter on SSB. Given the comments about ALC, this suggests to me
that the guy doesn't know how to drive an amplifier. Most amps don't require
ALC feedback if you adjust them correctly in the first place. More
important, ALC doesn't always work well. You really have to design both
circuits together for it to work properly, and that's obviously not the case
when you pair random transceivers and amplifiers. Not clear that the guy did
the ALC mod, but even if he did it's not guaranteed to produce optimum
results under all conditions. With amps out of sight in the basement, he's
probably overdriving them and/or not tuning them properly for maximum gain,
and thus creating splatter.
