mc cartridge loading


I currently load an Audio Technica ART9 at 90 ohms, the load 'inherited' from another cartridge, am pleased with the sound but recognize the manufacturer's recommendation that at least 100 ohms be used.  Changing load requires opening the phono-amplifier case, somewhat tedious.   Is increasing the resistance (decreasing the load) worth the effort?

In all the years I have been reading and talking to engineers who are involved with step up trans and carts this is the first time I ever heard this.

You can argue that the best impedance match on paper might not be the best sounding one.  But there Is a difference in sound.  It sounds like he may not want to go through the effort to experiment but it may be well worth the effort in his system.

You might look to some other forums where there are a lot of comment on this subject.

The rules in audio are like the rules in economics.  Everyone likes to believe they have the answers but the outcome varies because we Do Not know all the variables.

In regards to your ears not being the ultimate test well that is exactly what they are.  You have to listen to it.  We can argue who can hear and who can not.  We can also argue with tradeoffs involved where are your priorities but these goals will only be met by using your ears.

Never looked at a sine wave on my scope and started dancing.  The one size fits all in audio is Well optimistic!!!  I build all my own gear so I am lucky. I can change everything around a million different ways.  I do not have to show the bean counters where the profit is or explain why I went down this dead end road.

So the moral of the story for the original post is the Only way he is going to know in his system is to experiment with different resistor types and values.  Then listen.  If that 2 dollar resistor puts a smile on his face who cares if it is real or in his head.
