Would you use an Ortofon A90 on a Jelco tonearm?

Dear @pani : Ask you somenthing like this: would I send my " Ferrari " to fix it at Ford or GM?

In the case of top LOMC cartridges it's just a mistake to send the cartridge to and after market re-tippers.

When we send the cartridge to the original manufacturer we have several advantages: first is that it signature quality sound level does not changes, second is that the cartridge manufacturer not only fix the cartridge but if exist any additional " problem " , that re-tippers can't detect, they will fixed, if at the time we send the cartridge to the manufacturer exist any kind of up-date ( unknow for us. ) they will do it free of charge ( this happens with any manufacturer not only Ortofon but Lyra or van  den Hul. )

No re-tipper can knows all the why's that the cartridge designers took in count for the whole cartridge design. It was the  designer whom made the cartridge voicing till he was satisfied with.
When the cartridge is sended to the manufacturer they check the overall design and that the cartridge meets the specific specifications for that model. Re-tippers can't do it and not because theirs knowledge levels that allmost all have but because they do not know critical information only the designers have.

When we send a top cartridge to re-tippers what we recieve is a different cartridge.

So it's up to each one of us.

Regards and enjoy the MUSIC NOT DISTORTIONS,

I don't think that Soundsmith does but I believe Andy does.  Could be wrong about Soundsmith though.

I have a Winfield and like it a lot.  The cartridge is very flat...just tells the truth.  The caution is that it is VERY sensitive to setup.  I've had many cartridges...none even approached the sensitivity of the Winfield...especially as to the azimuth adjustment.  I have it on a VPI 3D with the 2nd pivot...just by changing the azimuth the most minute adjustment on the screw, the soundstage width and depth open up dramatically.  If your arm doesn't have all adjustments that can easily be manipulated, I would probably look at a Benz LP or similar.

I found the Benz sound to be a little fat for my system and liking.   Tried 2 of them one was the gold and the other the reference. Reference was supposed to be quite good 

Windfeld is very very good but not a match for either of my 2 arms. I'm sticking with a vdh colibri and a Lyra helikon.
