info on Grado Signature arm

I wa lucky enough to recieve a SOTA Signature Saphire table with a Grado Signature arm and a Grado XTL (I believe) cartridge, the table has the top of the line clamp and the Vac hold-dowm, as this was all free I am thrilled to think in my position in life I am getting the best that I could ever do.....it being a gift is simply amazing but I need to know if anyone has info they can share about this set-up.
I am also curious if I should explore a re-tip of the Stylus or install my Clear Audio Aura Beta cartridge.
I did a few searches but find it a difficult task to weed thru all "related" items it presents.
I know that tis is an old table and nothing that will raise alot of eye brows around these parts but being on fixed income I cant tell you how excited I am to be so lucky and any info would be very much appreciated1
Thanks again all and Happy Holidays......Chad
