NOS Grace F9E question


A friend of mine gave me a Grace F9E to try on my 1200G.  He thinks it may be a good fit.  It appears to be brand new and never used.  It has a plastic protector that covers practically the entire cartridge.  I cannot get it off as it is on there very tight.  Is there any special way to get it of and not damage the cartridge?

Any suggestions would be appreciated.

Der @lewm : Between other ADC used titanium too. Btw, when I talk about MM I'm reffering to all: induced magnet, moving iron, moving flux, electrect, etc. etc. I'm refering to non MC cartridges.

Koetsu are solid boron. Even that hollow boron could lower the moving mass the trade-offs against it are to high.

Now, what makes  the greatness of any cartridge is the sum of the parts and its quality excecution. In that sum of the parts the motor is the must important issue: it's " the design ". Cantilever and stylus shapes are only variations but what live on/trhive is the cartridge motor.

Acutex used titanium cantilever in its top models.  I don't know of any other manufacturer that did that, but could be.

Victor X-1IIe has titanium pipe cantilever
Audio-Technica AT150Ti has titanium cantilever too 
One of the Grace LEVEL II variations has even Ceramic Cantilever  
And ceramic is good because...?
Ceramic tt mats suck.

For that matter, I would not claim that titanium makes a great cantilever, only that the Acutex sounds great, to me, in my system.
@lewm my grace titanium stylus replacement is still sealed, never tried.

Victor X-1IIe with titanium cantilever and elliptical stylus is superb MM cartridge, only one step behind the X-1II with beryllium/shibata

In my opinion Victor X-1IIe is much better than Grace F9e
@lewm oops, i meant Grace Ceramic cantilever in my previous post, not Titanium
