upgrade from my BENZ ACE low output MC cartridge

Mirror, Benz has not changed the ACE yet retail has gone up 350 dollars. Why? It is a giant killer. The differences between my Ace L and Ruby III L are startlingly small. Have you considered a better phono pre? You don't say what you are using. Z,

Thank you guys for all responses. I am using a build by my own pre and turntable. Turntable platter and bearing is from Thorens, motor is DC brushless outboard beltdriven, arm is SME 3009 II. The phono pre is tube based on 12AX7 first tube and 12AT7 second. Step up is tube also 12AX7. I am really happy with the pre. It has also impedance match for different setups. I like the detailed, not clinical liquid sound of Benz. I was also thinking about Shelter as an option, but never compared both. What do you think about Shelter as a cartridge?
Thanks a lot!

I have more questions. What is the difference between new S series and the old one? Any opinions on low and medium output versions?
Thanks!

I bought a Shelter 90X used once, as a backup for my XV-1s. I don't know if the Shelter was worned out but I never got the best out of it. Even if I didn't got this cartridge right I could tell it had very nice dynamics, excellent tonal balance and a powerfull bass. I would not blame Shelter for the sibilants I never got rid of. I might have recieved a worn out cartridge in the first place.

So, in my opinion the Shelters are excellent. But I believe it's difficult to tell which is the better choice when I don't know the system.
