SUT help

Your MC stage of your Phono Stage IS A SUT.

ALL MC low signal in/MM strength out are SUTs.

Your Phono has a terrific set of optional Loading:

ModWright PH 9.0

MC Loading: 10-20-50-100-250-470

And, independent and adjustable gain is the holy grail IMO.

.............................

IOW, you already have an EXCELLENT SUT

and, SUTs are not supposed to have a sound, exactly the opposite, just step it up without changing the sound of the cartridge or the sound of the MM Phono Stage.

....................................

Additional Cartridges: the sound of any cartridge you have/get needs to get thru a SUT without alteration. I’d put money on the fact that your ModWright does just that.

Aside from researching/considering any cartridge's sound characteristics, which are ’preferred, not better’, I always encourage looking for technical specs: wide channel separation, and tight channel balance, the combo yields terrific imaging of the ’preferred’ cartridge sound.

@elliottbnewcombjr Your Statement:  

"SUTs are not supposed to have a sound, exactly the opposite,"

"Your MC stage of your Phono Stage IS A SUT."

Are these statements based as the outcome of personally experiencing a Broad Range of Phonostages in use, where MC Inputs, or as you describe ( On Board SUT's ) are assessed for how the end sound produced by the system overall, impacts on your own unique preferences for produced sound ?

Similarly, the SUT / Head Amp Off Board and connected to the MM Input. Are your comments made as the outcome of having personally experienced Broad Range of these configurations. Which have been assessed for how the end sound being produced by the system overall, impacts on your own unique preferences for produced sound ? 

My experiences of MC Inputs and Off Board SUT's used with the MM Input, leaves myself with the perception that a Richness of Tone will be added when a SUT is used with the MM Input. 

I do not class this as a unwanted perception, I am encouraging those interested to be aware there will be a perception of some type detected, and it their unique tolerance of the perceived presence, that will be influential in making a added device become an attractor or to be repelled.

One SUT experience is not a broad experience of SUT's and the influence a SUT can have is not likely to be realised from limited exposure to the devices.

I though my own Journey was concluded with SUT's, Head Amp's were of Interest, then along come Sculpture A, and SUT's are of real interest once more.  

Another Link from a broad range of experienced forum members making the case for Off Board SUT > MM Input a option in discussions on Phon's that will cost the price of a nearly new used vehicle.

SUTs are like seasoning on food.  They definitely change the sound, it is silly to think they don't.  Silver wire sounds different than copper, the core material matters, how they are wound etc. also matters.  They are not everyone's cuppa.  No matter.  Everyone should make up their own mind based on their own experience. They work better with some phono stages than others, some cartridges than others.  They are just another tool in the box.  No more, no less.  Best to keep an open mind.

@billstevenson is 200% correct, but use bad A fantastic low capacitance cables and keep connectors very clean… which is also why the OP should contact the MOD at Modwr@lewm good idea.

As to a cartridge as a consumable…. yep, no kidding as are all your tubes…. just part of the journey……

I really hope my surviving kin don’t engrave “ here lies a frugal phono cartridge spendthrift “…. on my tombstone…..
