Knowing Nothing About Capacitance...

OK, I've had a table for 5 years now, have tried numerous phono stages and numerous carts, and am enjoying the hell out of my low-fi vinyl system. But after all this time, I'm still clueless about the relationships between cartridge specs and preamp specs.

For example, I'm now using an AT-OC9ml mk ii MC cart -- on the spec sheet it says that this cart's load capacitance is 20ohms. I picked up a vintage Denon integrated amp that I want to try -- it's MC phono section says that it's set for 100ohms. What does this mean? I know I can use the AT with the Denon, but I'm assuming that there will be some compromise in the match. (Whether it's an audible compromise, I have no idea.)

How does all this cart-preamp load matching work? Please keep it simple. I have a PhD, but it' not in anything like this. My scientific understanding peaked in 7th grade (40 years ago) and has gone downhill ever since.

Thanks,
Rich

Dear Rich: Maybe you make an error when you write the thread because capacitance is measured in uf not Ohms, Ohms are for impedance. Btw, 100 Ohms will be fine with your cartridge no problem about.

Regards and enjoy the music.

Dear Rich: I think that is the load impedance through a step-up transformer.
