Added an SUT...not sure I understood this
@woofhaven1992   The reason a cartridge sounds different under a heavy load is because the low load impedance suppresses output voltage. so add more gain.  I'm not trying to be cheeky here but this becomes a problem related to what happens dow...

JCarr makes the exact point I am ultimately trying to get to when he says the below.  Also, IV phono stages sound qualitatively different to voltage amplification phono stages., and part the reason is that undoubtedly the cartridge is forced to ...

The maximum output of the cartridge will be with little or no load. 47K is the industry standard in this regard. the industry standard of 47kΩ was adopted from the MM cartridge world and applied to the MC realm because is first and foremost "do...

@dover  the last post in this thread from the OP is below: @dover The sheet that came with my cart says 20 ohms. AT has not been consistent with their specs on the OC9 series.  More importantly, it sounds better around 20 ohms than at 100.  Ple...

apologies to all for veering off topic here.... @dover  I have yet to se actual measured frequency sweeps from a MC cartridge that show the ""rolled off" top end you suggest above.  Can you point me to some? The only reason I took the time to ...

@dover  Do you not think the cartridge designer and manufacturer knows what they are doing when they recommend a minimum of 100ohms ? If I had to guess that spec is set to assure near maximum output of the cartridge.  Changing the loading valu...

@dover  The recommended loading for your cartridge is Min 100 ohms. Min means minimum and If it sounds better at 20 ohms, there must be something wrong with your system. since the OP has solved his issue I have to ask if 100Ω is minimum a...

getting back to the OP.... He seems to state that he expects 6-8dB of gain in place of the nearly 20dB that a 1:10 suggests.  He then says he is getting the opposite effect which I take as less gain.   for the OP. In sticking with just the 40Ω (... 
Why do tonearm specifications list null points?
You need a mirrored surface with lines finely etched and magnification.   and certainty that the diamond tracing faces (assuming advanced profile) are aligned precisely 90° to the cantilever. dave  
Cartridge Loading.....Part II
I suspect that the mention of Lenz's Law with respect to back EMF may be a bit misplaced here.  The simple story of back EMF when it comes to a speaker is the inertia forces the cone to continue to move after the signal tells it to 'stop and go th... 
Fact or misinformation?
There is vertical compliance to keep the tip in the groove and handle record warps. Just higher compliance laterally. No vertical compliance means the stylus bounces in the groove from record warps. yes... and interestingly enough the choice of... 
Fact or misinformation?
Lew, I agree that a mono switch helps.  The big thing it does is converts all the noise to a mono signal since having mono music and stereo noise is very distracting.  All of this based on the evil premise to some that you are listening to mono i... 
Fact or misinformation?
But either way its a compliant diamond sliding through wiggles. A stereo needle will simply pick up the exact same movement on both channels. I do not see how this will damage anything. It comes down to whether the playback cartridge has verti... 
Fact or misinformation?
The big difference between a mono cartridge and a stereo cartridge comes down to noise pickup.  A true mono cartridge has the coils oriented to only pickup info in the lateral direction whereas a stereo cartridge is oriented with the coils at 45° ... 
Fact or misinformation?
No. The situation where damage can occur is playing a stereo record with a mono cartridge that has "normal" lateral compliance and little or no vertical compliance. dave
