Graham Phantom DV XV-1s setup question

The Set Up is a bit individual, for example the loading. 100 ohms with Phonostage A is not identical with Phonostage B. It is like a chain, Phonocable, Gain from Preamp, Amp and so on. My choice would be in the 1k area, but it depends on the Phonostage or System.
I would use the range of recommended tracking fore, around 2.0 gr to be on the safe side. Too much is bad for the cantilever and there is also a compression in sound.
Bearing fluid
I use very little of it, it will need some time to settle (room temperature) or you can try a little bit of bearing oil instead.
The break in time is overrated, after a few hours it is the way it is, in general.
Next is that the owner gets used to the Presentation and accept it the way it is (or not). I am skeptical to answers when someone write, the Performance changed dramatically after 100h. I never had this in 15 years with my cartridges.

I closed the chapter demagging/fluxbusting 10 years ago. And yes, I had this Audio Physics unit. I developed this idea, because I didn't want to ruin my cartridge, looked for an indian medicine man and found a retired Apache. 2x a week he dances around my Turntable, charges me a few $ and it sounds better after that. No danger and good for my garden, too. When he leaves my place, it is raining, too.

In our High End world there is a Theory for everything. Later you see, what was really right and what is (was) more or less a mistake.
"Fluxbusting" is a typical High End result.
Of course you will find an exception for everything, but in general the Degauss makes the Permanent Magnets weak after several times of use. We noticed, that the cartridge needs "this" in always shorter periods (like a junkie), the Dynamic ability is reduced time after time, the magnetic field is getting more and more weak.
A real no-go (for me).
There are some exceptions, when some magnets are covered with dust which contains some metal parts, here it can help.
In Germany (or some other countries) some companies "refurbish" old magnets from speakers, they reactivate their magnets to full, new specs. this is not cheap. Maybe they are doing something wrong.

Honestly, I forgot that. I have the Cardas record, too, but can't remember when I used it the last time. I used it a few times at my "Fluxbusting-Time", but I guess, this chapter wasn't really important for me.
