I want to thank @gasherbaum for posting the final outcome. So many OPs do not. If anyone stumbles across this while researching their own journey, I have a few suggestions.
First, a real good set of headphones helps when your schlepping around for demos. They at least take different speakers out of the equation.
Second, I wouldn't let a high cost phonostage compromise my budget on the TT/TA/cartridge/cables. I got a used Musical Surroundings Phonomena II for $295 until I find something that will best it at a reasonable cost. It is quite capable of revealing subtle differences between cartridges and the way they are set up. I am still looking for something I am willing to spend more on, and I have the best turntable and arm I will ever need. Cartridges are another story. I can't seem to stop collecting them.
