Re-tip or Replace?


I have a 40 year old Dynavector Ruby that still sounds great, but I think it will soon require a re-tip.  The question is, should I pay the $350 or so to retip it, or replace the cartridge with a comparably priced Ortofon, Audio-Technica or Nagaoka?  The system consists of a Luxman PD-277 turntable (another 40 year old piece), Schiit Mani phono preamp, Schiit Saga preamp, Rotel RB-980BX amp, and Martin Logan ESL speakers.

Thanks in advance for any advice.

jnorris, replace it. The little wires inside that connect the coils to the pins are subject to fatigue and work hardening from years of vibration. They will eventually fail and then the cartridge is done. I would not spend money on a 40 year old cartridge for this reason. Have fun getting a new one! the Audio Technica AT ART9 and the Ortofon Quintet Black S are both great cartridges and great values. Both will work very well in your arm.

Re-tip or replace what? You will get more helpful responses if you use a specific subject. 
Buy a new cartridge. Replacing the diamond with a new one and a blob of glue will compromise performance! 
You can wait for a nice deal on ebay, i bought my rare DV 23RS MR (with Micro Ridge stylus) NOS from USA for about $450-500 one year ago. This is very close to what some people change just for a drop of glue and a new stylus tip. So i think you can buy a whole cartridge, even unused in the box.

Some other cartridges can be found too, but for $350 it will be hard to find anything close to DV23 Ruby, those new MM are not that good.

In my opinion it is much better to pay more for original cartridge than to mess up with retip.
