I'm having to cobble together an interim phono premap solution,

and I'd be

grateful for some advice.

I've got a MF LPS phono amplifier rated at 100 ohms input

impedence for

the MC bit, and an AT OC9 cartridge rated at 20 ohms load

impedence.

Does this matter?

**Nope.


If so, how do I correct it?

**Don't bother.

The 'old' electronics rule was always low Z source, high Z load, so,
as it says above, provided you have enough gain it will not be a
problem.

Many thanks both - it certainly seems loud enough. I've just googled 'z
load', and apart from bafflement, the other variable seems to be the
cable. How do you measure the impedence of a cable?!

I'm sure it doesn't matter, just curious :-)

**With a source impedance as low as that of a MC cart, it is not important.
With MM carts, cable characteristics can be VERY important.
