Moving magnet cartridges are designed to operate ideally within a set capacitance range, measured in picofarads (pF). The Audio Technica 540ML is notorious example of a cartridge being very sensitive to capacitance, and thus causing some folks to lessen the capacitance of their interconnects to get the cartridge to play nice. The 540ML works best with 100-200pF being ideal, and going over 200 can cause some brightness, both measurable and audible. Having 0 added capacitance by your phono stage means the tonearm wiring and TT>phono interconnects are the only things adding capacitance. Having adjustable input capacitance is nice, having zero is probably the next best thing.

Unless you’re trying to use it with a Shure V15 III that likes >400pf and your new TT wires and rca plugs account for 150pf. This was poor planning on my part. Shit.

This is an advantage of a high output MC cartridge - MCs are mostly insensitive to capacitance.

When I used MMs, I purchased a Blue Jeans Cable LC-1 interconnect for the cartridge to the phonostage path; LC-1 cable has unusually low capacitance. It produced a subjectively better result from a Sutherland Insight when using Ortofon 2M cartridges.

The 20/20 is a different beast, though. It was rated Class A by Stereophile when it was introduced, indicating exceptional top-tier performance. From what others have written here, the performance may be improved still when using a SUT with conventional Sutherland phonos.

Edit: Of course, one typically uses a SUT with a low-output MC - not a MM.

Now that I'm using a Luxman PD-151 as my main table, it has captive RCA leads and I have no idea what the capacitance of those are. But, since I only use MC carts on it, I don't worry about it either! I did use a MI Nagaoka on it for a few weeks and I enjoyed it, but ultimately I went back to a Hana ML which has remained in place ever since.

I'd bet a dollar that the info is available in the "Luxman" thread on SHF. The Luxman owners over there are all very math-happy (this is not a dig)
 
I was looking at and should have stuck with the Musical Fidelity M6x Phono perhaps. Will have to see how difficult it is to swap out the rcas for a higher capacitance option.

You can have BJC fab you an extension Belden RCA that has sufficient capacitance, if you want to take it that far.

How does this work? Does it attach to the existing cables with a splitter or would this be a new set that I’d need to mate with the tonearm?

Yes. It would have female RCA plugs on one end and male plugs on the other. It depends on the model number of the cable as to how long it would be, but Belden has lots of shielded coax cable options.
 
You could always use a pair of these together with some RCA loading plugs

Another option might be a loading plug. I've heard of these for resistors, but not for capacitors - still could be a possibility.

From time to time there is interest in varying the loading of various cartridges. As a reference...

@Slimwhit33 - You also solved a puzzle for me. I wondered for a while why anyone would need to add up to 188 pF (top setting on my Bryston) for a MM cartridge, with me being used to Ortofons with low capacitance requirements. I didn't know that these classic Shure cartridges had such high capacitance specifications.
