Question about Cartridge Loading


Hello All,

Out of all the different audio components, seems like the phono amp is still something that I am trying to understand.

I have read much about it here on the forums, google and YouTube.

But I haven’t really come across a simple answer as to how different resistance (ohm settings) affects the sound and that is what I am trying to get to and understand.

I have very basic electrical knowledge but understand that the different cartridge loading values: 100, 200, 300, 47K, etc are different values of resistance.

By the way, I understand Gain. Higher the Gain, the louder it will be (ever so slightly).

Also, I am not worried about capacitance settings since I use a MC Cart.

So, in the most simplest terms, what I want to understand is if for example, if a 100 ohm setting is chosen on a phone preamp, does that mean the audio will be more open because there is less resistance compared to say a 600 ohm setting?

Would 47K damp the sound even more because it is a higher resistance value compared to 100 ohm.

In my mind, resistance means to push back or down, so I would think a lower ohm setting mean that audio output would sound more free/open not as veiled, perhaps more bass.

Am I thinking about this the correct way?

I know it’s probably not as simple as that.

Currently, I can’t seem to detect much different in the different load values with my phono pre-amp.

Anyways, any feedback would be welcomed.

As I said, I am looking for simple answers like: lower ohm setting equals more open sound and higher ohm setting equals more veiled sound (I’m sure I am totally wrong about that as there are many variables involved).

Thanks

Jay
