Dear friends all of you: I sended an email to J.Alaerts and VDH, I´m customer of both cartridge design true EXPERT manufacturers not new comers or rookies. I asked about cartridge importance against tonearm importance in an analog rig and this is what they answer me:

Hi Raul ,
I think that the cartridge is 500 % more important is as the arm , the arm is only the tool that must keep the cartridge on his position , no more no less , and also that is important that for my cartridges the masa from the arm can have 10 Gr , weight cartridges , if this is correct its only to adjust the arm correct and you can play , but for music and dynamic range and accurate , is the cartridge the most important piece , better , the cartridge is the source and first in line , so actually the MOST IMPORTANT PIECE from a High Tech installation , don’t let you involve with some other explanations , OK,
Best Regards
Jan. """
When I lended my Allaerts MC2 Finish Gold to M.Fremer for review was because I asked before to Stereophile why no Allaerts cartridge review and they told me that they asked for review sample two times but Allaerts always was and still is back ordered.
Any gentleman that wants to buy a MC2 Formula 1 needs to send payment in advance ( around 20K. ) and wait 3-6 months to receive his cartridge.
Allaerts does not needs advertazing or reviews, normally is back_ordered in the two top cartridge models.
here you can read the specs of the Formula 1:

Btw, Jan use Yorke analog rig, Simos builds only six units by year and only on custom order.
Obviously that the Allaerts cartridge owner needs a really top SS Phonolinepreamp as is the level of CH or FM Acoustics and obviously too no single tubes down there ( this is absolutely out of question. ).
The information by VDH:
" After the cartridge, the arm is the next important item on a turntable. It is therefore important what material(s) and construction are applied. Any arm transmits the mechano-acoustical energy of the cartridge and is also a mechanical resonator itself. Both effects are unpleasant because both change the replay quality in their own specific way. "
this is one model I own from VDH:
