How are you playing your precious MONO Vinyl?
If you look at graphs of the various curves generated by the different algorithms, they are not terribly different from one another, because after all the goal was essentially the same.  So I might be happily listening to some of my 50s mono LPs w... 
Grade Master3 cartridge--Moving Iron Design
Pickering is listed in the legend to your figure after point #2, as an example of "moving magnet". As I am sure you know, Pickering and Stanton were associated with each other. Most models of Pickering have a corresponding model among Stanton cart... 
SUT Interconnects
What Atmasphere said, but be sure to disconnect the cable at both ends before taking a measurement.  For a balanced cable, the measurement between pins 2 and 3 (positive to negative phase) will be equal to about 0.5X the capacitance between pin 2 ...

Pickering and Stanton are MM, so far as I know. All of them.  
Grade Master3 cartridge--Moving Iron Design
Peter L started out, I think, repairing B&O cartridges, which are all MI types, and the best of them can compete with any modern cartridge, IMO. That, I am guessing is how he got into the MI business. Even now he makes the SMMC line which is a...

I don't have any phono stages with options for the de-emphasis curve.  They are all RIAA.  And since this one pair of LPs on EMI are the only LPs where I have ever noticed a possible problem, it has not and will not be worth my while to buy one.  ...

Not a groove expert. I only have read what I wrote, which only applies to the 33 rpm era post ~1948.   
How are you playing your precious MONO Vinyl?
A "two channel mono phono preamp" is any phono preamp or phono driving a linestage where the mono mode is engaged, when you feed that phono section with a true mono cartridge. Lalitk, I don’t understand exactly what you are after. If you want to g...

"Mono LPs pressed from 1948 until the early-mid 60’s have a groove width of 1mil.  Mono LPs pressed after the mid 60’s and including current mono reissue LPs have a groove width of .07mil...a smaller groove width. " Not that it matters much, beca... 
How are you playing your precious MONO Vinyl?
"Some believe that the presence of vertical content that is then summed introduces distortion and phase anomalies that are audible." Whether or not such distortions are "audible" is a matter for belief or individual acuity, but whether there is d... 
Rega reference belt disappointment
Yep. Armorall, their original product, is now out of favor because it dries out the rubber even on tires. They do make other useful products.  
Your thoughts or experiences with two specific turntables: Thorens 124 DD vs SME Model 12
The OP is referring to the NEW TD124, which I didn’t know existed until now. Apparently it’s direct drive and therefore very different from the classic TD124, which is probably a good thing so far as I’m concerned.  
Rega reference belt disappointment
In the long run, Armorall , at least the original product that makes rubber tires shiny, is not a good choice for a TT belt because it may make the belt slippery and also may dry it out prematurely.  
Why Use Aluminum for a TT Platter?
Teres TTs were the last of the wood platter TTs, so far as I know. I think Chris is still available for comment. But these days there are no other examples.  
Where to start upgrading?
Better to think about what makes a “good” cable and why in terms of the physics. That is a thorny set of questions because it depends upon the nature of the output of the driver and the input of the driven component. In my opinion it’s a bit less ...
