Understanding impedence matching

I am a psychologist and my eyes start crossing when the conversation gets too technical, but that being said, I am beginning to wonder what impedence matching means and what I should pay attention to as I upgrade my setup.

The two pieces in my system that are likely here to stay for a while are my SF Electra Amator II, that evidently don't drop below 6 ohmns, making them receptive to an OTL amp, and my Cary pre, that has phono impedence @ 47K (evidently this can be adjusted) and output at 800 ohms. I am in the process of upgrading my amp and TT.

What does this mean in terms of how I think about these two acquisitions?? Are there specific numbers I need to pay attention to, and/or formulas for these, or is it all in the listening?

As always, thanks for your help. This community is amazing.

Chuck --
investing a little time in understanding Ohm's law will take you a long way towards understanding these issues. It's a bit like learning a language: in the beginning it feels daunting and impossible and then, suddenly, you loosen up & speak the language... you've acquired the "knowledge" as it were.

OK, you may not be ready to design your own amps, etc -- but, as Clueless (and not a physicist:)) notes,
if folks understood ...(that)... (and a little RLC) about 3/4 of the magic and synergy would disappear from the wires used in audio
However, the magic of matching devices into a system would appear.

Try this link, too. It's a short introduction to electricity & components.
It can be fascinating!
