Ortofon MC A90 cartridge

Tobes & All,
I do agree in every respect with what you're saying, yet let me throw out one more curve ball.
The Windfeld I'm referring to is a new replacement of an earlier one that had issues also acknowledged by Ortofon (who replaced it for no charge), having "a VTA problem".
It was "riding" VERY low from the start and the body was not build / assembled up to scratch either.
So it could be explained that the two would've behaved quite differently.
The new item is now riding a lot higher and this *may* just be the way the first would have meant to be? (In fact I'm not so sure at all!)
A similar story with slightly different faults I had with a Jubilee, which also was replaced eventually after 2 attempts to correct the initial problems (body gapping and more and more skewing cantilever).
I mention these so as to explain why I think (by now), that there are rather more variations in these carts then one could wish for.
The MP-50 I mentioned by comparison is CLEARLY! a better tracker (then the Jubilees, or Windfelds in my system) and those two Ortos are *supposed* to be GREAT tracking carts!
There have been some very long threads on explaining mis-tracking, of difficult vinyl bands and not just IGD i.e. the inner bands only, and none of those Ortos did too well for me ever.
In fact, it seems this form of mild to more sever mis-tracking that makes these carts lack in ultimate "clarity" and I can no more easily explain it in terms of a lesser phono-pre performance. By now more then one MM or MI cart seems to disprove these ideas of insufficient rise time and the like.
It looks now that the A90 has finally got this sorted, reading the above reports about *superior clarity* --- very GOOD!
Now why only build 400!? Marketing? More then 400 ought be sold by now in any case...!
Using those carts mentioned in an SME V arm should NOT be the limiting factor AT ALL.
Just food for thought, and possibly an opportunity for some more learning.

Axel, A90 vs M20FL Super? Any comments?

Hey Tobes.

I use an Ortofon Windfeld and have recently purchased the A90 which is an absolute KILLER cartridge. I found using the Windfeld below 100ohms sort of killed the music and so far the A90 below 100ohms pretty much does the same.
I use a solid state based phono stage. Above 100ohms both cartridges 'warm up' slightly but I prefer the 100ohms setting IN MY SYSTEM!.

Just as a comparison for anyone wanting to know:

So far nothing compares to the A90 in my system.

Windfeld vs Airy 3 = Windfeld wins outright in all departments.

Windfeld vs Shelter 901 = 901 sounds livelier but 'false'

Shelter 901 vs Airy 3 = I prefer the 901 as is has far better weight and realism. 3D portrayal is far better with the 901.

901 vs Ortofon Rondo Bronze = 901 wins outright which goes to show a good cartridge is and will always be a good cartridge.

Koetsu Red Signature vs A90 = Koetsu sounds OLD!

Koetsu RS vs Windfeld = Koetsu sounds OLD!

I have all of the above cartridges and all these were compared in my system using my standard setup.
VPI HRX/ Kuzma 4 point Whest Audio MC REF V phonostage/ LAMM L2/ ATC 150 Active.

Lewm,
sorry I have no A90, only the Windfeld and the M20FL-super sounds more natural, has more detail yet, and also is a better tracker! (It's why it sounds better also, my take)
It's why I said, this A90 as it's assessed above is the next important step for Orto, no?

Windfeld compared to MP-50 -- the Windfeld sounds OLD (good way of putting it, thanks for the expression Robm1)

PS: To me there's no way to give these LOMCs the credit of "unsuitable" phono-pre performance if it can deliver the good stuff with all those MM / MI carts. Again, I think it is clearly a tracking issue, -- at least with my SME V arm.

Dear Axelwhal: Yes a " tracking issue " could be. I posted ( two years ago in that long MM/MI thread. ) this:

+++++ " IMHO I think that the MUSIC run so easily through a MM cartridge due ( between other facts ) to its very high compliance characteristic on almost any MM cartridge.

This very high compliance permit ( between other things like be less sensitive to out-center hole records. ) to these cartridges stay always in contact with the groove and never loose that groove contact not even on the grooves that were recorded at very high velocity, something that a low/medium cartridge compliance can’t achieve, due to this low/medium compliance characteristic the MC cartridges loose ( time to time and depending of the recorded velocity ) groove contact ( minute extremely minute loose contact, but exist. ) and the quality sound performance suffer about and we can hear it, the same pass with the MC cartridges when are playing the inner grooves on a record instead the very high compliance MM cartridges because has better tracking drive perform better than the MC ones at inner record grooves and here too we can hear it. " +++++

IMHO this along each cartridge suspension design are important factors on the tracking issue.

Regards and enjoy the music,
Raul.
