In summery, in my opinion, a pre-selector would be a good bet to improve
portable reception when connected to an external antenna especially the
worse case single conversion units. Following that in usefulness would
be an antenna tuner. People chasing DX with tabletop units might want to
try antenna tuners where less useful for them would be pre-selector use.

And, I would pre-sume the "pre-amp" is different from the
pre-selector?

Good assumption.

I'm not big on pre-amps because they add their own noise to the existing
signal to noise but they can help. For an amp the be a help it must be
low noise and the best location would be at the antenna. Amps are best
used where you have a long run of coax. Other feature enhancements of
the amp design can come into play to make them more valuable.
