A stylus has about a 2000 hour life span so you do the math! The lower output Grado has less windings and your preamp might not have enough gain.
You would have to find out the input sensitivity of your phono(.5mv or less)to make sure the lower output will work!
I use the 1.5 version of the Sonata which is called Sonata VPI!
I don't think your system would benefit with the more expensive Master!
For $400 the Needle Doctor will give you a new one with trade,they do not replace the stylus on them,they just replace the whole cartridge!
BTW: I am a big fan of Grado I have been using them for over 30 years!
