Playing with Cartirdge loading on my phono stage


I have a Linn Eurphoric that has multiple loading for cartridges.  The Dealer set me up for the recommended loading for my cartirdge (linn Krystal).  What if any changes in SQ  can I expect by changing the loading on the phono stage?

 

Thanks all

It would be better to use a distortion analyzer, but this would only be of benefit if the phono section can't deal with the RFI on its own. If the phono section does deal with the RFI properly, you'll see no benefit from the loading in terms of distortion.

@atmasphere thanks Ralph - what would the distortion look like? IMD, noise, or HD.

I am guessing it might look like IMD beating an RF tone against the audio signal??

Asking because I can digitise the TT signal, and look at it spectrally and do some math on it. Just need to know what to look for… (Like everything other than the specific test record tone freq?)

@holmz That is going to depend on how the phono section reacts to the RFI and IME that depends largely on the circuit itself so a blanket answer will be inaccurate. If it were me I would be looking at all those things. Its also worth noting that the electrical resonance may not always be in excitation- so it will come and go in certain circumstances.

Thanks @atmasphere - Ralph you are a gentleman, and your thoughts, and guidance, are very much appreciated.
