Impedance Question?

OK so I know there's a lot of threads about matching impedance with pre/amp.  It would be really nice if someone could help out here! The whole impedance thing confuses me (doesn't take much).

So if I have an amp that has 10k impedance what range for output impedance would work for a preamp?

Any help would be great!

Hi!

The issue is almost entirely related to tubes. The manufacturer will usually recommend a minimum recommended impedance, and anything more is better.

Stereophile will also test preamps with a variety of loads, and report on the effects,.

Best,

And of course I'm talking tube pre and ss amp combo.  Hope this helps!

Quick and dirty answer: you want the amp to have an input impedance at least 10x the output impedance of the pre.
