This is the 3rd branch of Physics called Audiophile Physics it's well established and is more difficult to measure than Quantum Physics. (Joke)
Definition of QP, taken from a discussion:
"Quantum physics is usually just intimidating from the get-go. It's kind of weird and can seem counter-intuitive, even for the physicists who deal with it every day."
So, the bottom line of it all is this babbling is SO complicated for the average person to understand, so they just "go along with it" as such.
"85 year old Mrs Smith can't make heads or tales of it, but bought the product anyway out of trusting the seller."
Her response: "They must know what their doing".

I return to the subject of reviewers and the Pro Ject Tube Box S.
I am targeting one of these, but I want to use two turntables, one equipped with an MM cartridge and one with an MC cartridge.
It never occurred to any reviewer - I've read a lot of reviews - that someone might want to do that ?, and this is a major counter.
Pro-Ject Tube Box S Phono Preamp Review | Top Tube Amplifier
A lower priced NAD PP2 pre has two independent inputs selectable from the rear panel, but on the Pro Ject a DIP switch (e.g. seven, 100 Ohms for Denon DL103) must be set to ON to use MC, and for this there is I have to turn the device over, which is uncomfortable, not practical, and I also suppose that the durability of the microswitch could be affected by using it regularly.
So I ask, a resistance of the value required by the MC cartridge, in parallel with the RCA connector of the TT would fulfill the same function? There is no circuit available, as always....

Your complain is of course justified to you, but you have to understand that being it's not normal for people to keep juggling turntables around, so manufacturers design it around what they assume is normal use, not audiophile obsession.
Plus, in this day and age, cutbacks are many.
Your usage isn't what the manufacturer thinks is common enough to satisfy installing a convenient switching arrangement.
I don't know the schematic of that preamp, so I cannot suggest a rewiring of it.
One could argue you are falling into the same trap as the reviewers with your belief that MC is somehow superior to MM.
I agree.
The bottom line is all about reproducing music from the groove with enough accuracy for enjoyment.
Indeed there are "tiers" of quality among cartridges, just like anything else.
However there comes a point of diminshing returns.
Additionally, the "purist" ways of thinking seem to abide by the "more is better" rule, so MC is the road to take, money and inconvenience is no object.
What happens when a MC cantilever is snapped off by accident, carelessness, or the pet cat?
You've now got to suffer the inconvenience and associated costs of either sending out the whole cartridge to be re-tipped, or buying a new one and having to mount it.
Those things are for the smaller audiophile community to deal with.
Yes, JM, just have it in my power, I will try to lift the input circuit, I imagine that the resistors with their own DIPs will be easily identifiable...
Many answers here but only JM thought of what I am interested in knowing, about loading impedance in the input cable and leaving the corresponding switch in OFF.
I know perfectly well that a good MM cartridge can outperform an entry-level MC, but that's not the point here. I have bought Denon DL103, and will play with the mass of the arm until it "sings".
And with regard to the tubes, in the Project they do act on the output, modifying the sound. It is not a cheap Chinese pre !

It seems that the originals are JJ electronics, I will see to change for a NOS 12AX7 and it will surely be a better sound, of course doing that will have its price, but I want to indulge myself, money is not a problem for me....

I live without cats or children and no one has permission to clean my TT. I only do it - if necessary - and you know that there is a thing called a stylus protector, it is only taken out to listen to the vinyls and it returns to its place immediately, it is a good habit acquired after finding the needle of a Shure V15 Type III broken many years ago....
And I will tell you that in your case that issue is not so worrisome, you live in the USA and finding a distributor of any MC cartridge to send it to the manufacturer and replace the needle should not be a problem.
Here it would be much more cumbersome, I would probably throw it away and buy another model to experiment ...

All well and good for you.
As for me, I've liked and preferred the convenience of having replacement styli in the house, user replaceable and quite satisfying MM/MI types.
