How old is your cartridge?

Build date

Mid 1960s - Decca C4E - checked over and retipped by John Wright (London Cartridges) - this is my main system "daily user"
Late 60s - Ortofon SL15 ELL - checked and paratrace retip by Expert Stylus
1981 - Decca Gold Garrott Bros rebuild with later retip by John Wright
1980s - Denon DL103CII - Expert Stylus white sapphire cantilever and paratrace - my study system "daily user"
2003 - Allaerts MC1B - rebuilt and retipped by JA - my other main system "daily user"
2000s - Garrott P77i

1980s - numerous others in the spare cupboard - all working
AKG P8ES Super Nova, Ortofon M20FL, Ortofon VMS30, NOS Grado FTE+

Currently listening to early 80's Pickering XSV/4000 on my Technics 1200 GR. I bought mine from Russian time traveler, NOS condition. It's excellent!

Todays cart flavor is the Pioneer PC-1000 mk2 with Beryllium cantilever. This cart was made in the 70's for legendary Pioneer Exclusive series of turntables and tonearms. Damn good!!!

I am using a pickering XSV 3000 with stereohedron stylus for the past two years nearly every day.  still sounds great.  I am starting to think the older MM have a longer lifespan due to the lower tracking force.

My daily driver is my 1967 Decca FFSS Mk IV C4E - just came back 2 weeks ago from John Wright (London cartridge designer) after an overhaul and new Paratrace tip. Whilst that was away, I was using my 1981 Garrott Brothers Decca Gold.
