Who's done it besides me ?

I weighed mine on a scale that was not made for checking the cartridge weight. The scale pulled the cartridge down and bent the cantilever. Expensive mistake!!

Yes, scales made with ferrous material that can be attracted to the magnets in a cartridge can be a problem.  The only time I came close to damaging a cartridge is when the balance type of scale I was using had a ferrous beam.  What is really crazy about this is that this was a Shure scale that is made to set tracking force on cartridges.  It obviously is only usable with MM-type cartridges which don't have permanent magnets, but, still this was a stupid design choice (an older Shure scale that I had utilized an aluminum beam).

I have numerous vintage MMs, particularly Shure and Grado.  I also have a bunch of MCs (mostly Denon but also Ortofon and Dynavector) and a Grado Statement Reference.  They all sound good, in different ways, with the right stylus.  It depends on the music and you taste.  I will say that when I rip LPs with my PS Audio Phono Converter I use a wood body Denon DL-103R with ruby cantilever and Line Contact tip, with a Denon AU 320 stepup,even though I could set the Phono Converter's gain high enough to not need the transformer.

IMHO, the MCs also need a stepup and very careful loading.  I've never heard an MC head amp sound as good as I can get it with any decent stepup transformer and a loading box. 

For a 10x stepup it's easy to know what load you are getting.  For example your stock 47k MM phono pre will present 470 ohms load through a 10x stepup.  For other stepup values the transformer formula and a calculator are helpful. 

The art lies in shunt loading your preamp inputs to get the sound you want.  RCA Ts at the inputs are needed. You can solder resistors across RCA plugs (the ones for making cables) and plug them in the Ts, or make a switchbox (loading box) and plug that in.  Just start at a net load of about or a little less than 2x the cart's resistance and bump it up until you hear the sweet spot. 

For example, a Denon DL-103 (not the "R") is 40 ohms.  I start at about net 75 ohms at the cart.  To get this with a 10x stepup I need to have 7.5k at my phono pre input.  With the parallel resistance formula I calculate I need 8.92k ohms in parallel with my 47k preamp.  We will want 1% tolerance resistors (E96 value table) so the closest values are 8.87k and 9.09k; either will be fine to start the listening.  Then bump it up by 5 to 10 ohms...

If you aren't willing to do this, or have it done for you, you won't get the most out of your MC.

tubehead120 I had no problem with the sound of my turntable really loved the sound of it my musical surroundings nova II is very flexible the problem I have is that I broke the @#$% cantilever off  and I'm most likely going to replace it with the same cartridge 

Wow just a handful I thought it would be in the hundreds if not thousands or are people embarrassed to admit that they have done it too
I still have not made the decision on the cartridge 

enjoy the music
