What do I do with these Cartridges


Hello all,
I've got a couple old Cartridges, a Sumo II MC and a Dynavector Ruby. On both, one of my wonderful children broke the cantelievers some years ago. Today, I listen to mostly computer audio and I have replaced these with an Audio Technica AT440MLA. It is fine for me these days.
Are these worth having repaired? Better to sell them as is? Not worth someone else to buy as is? or a No brainer, YES, get these repaired.
I haven't followed cartridges closely over the years, so I'm fairly clueless of their value. Thanks for your help, Tim

Thanks Elizabeth, sounds like they need to stay in the box that I have them sitting in, I'd need to get a Ruby cantiliever on the Dynavector, soundsmith gets $250 plus I'd have shipping both ways and shipping again when I sold the thing. Or if I ever wanted to use it again, then probably worth the investment... The old Sumo MC was quite good also, he gets Soundsmith gets $150 to replace a normal aluminum cantiliever. I guess I could most likely sell them through Agon, but if only getting a few bucks, I'll most likely hold on to them.
I do not know the Sumo... but the Dynavector ruby is a definite YES.

The current equivalent is the Dynavector Karat 17D3 (you can look that one up).

Soundsmith have been known to recantilever/repair these.

Alternatively you could sell it... but for the $300 odd that a retip would cost you, you would have a truly exceptional cartridge (Retail is currently well over $1000 I believe) - Of course I am assuming that you still have an MC phono stage to run it into.

bye for now

The Ruby does not sound anything like a 17D. It didn't when they were both brought out(23R-$310.00/17D-$650.00), and the Diamond has been improved, more yet, as of late(17D3 version). Damaged Karat Rubies bring about $50.00(average) on eBay. The Ruby was a good cartridge. The Diamond was/is a great one.
