Dynavector Karat 17D3: retip for $500 or get something new?


I have a Dynavector Karat 17D3 cartridge which I liked soundwise until it began to mistrack severely. Had it examined and it turned out the diamond is almost completely worn out.

I can get it retipped with the new Micro Ridge Stylus for $500. Alternatively, I can attempt to sell it, add $500-$600 and get another cartridge. The question is: can anything it the range of $700-800  sound better than a retipped "old" Karat? 

My system consists of Mitsubishi LT-30 turntable, Nakamichi CA-7A preamp, SONY TA-N330 ES power amp and Solstice MLTL speakers. Speakers are not very bass-efficient so the new cartridge shouldn't be bright.

ART-9 topic is irrelevant today, this is discontinued cartridge and our friend Pani replaced it with EMT 75th Anniversary after all, the hype is over. 
My Dynavector 17d2mk2 (for example) designed for light mass tonearms. The compliance at 100hz is 15cu and it’s about 27cu at 10hz - this is a high compliance for MC cartridge and tonearm choice is important. 
There are many unique features in Dynavector cartridges. Great cartridge, the rest is just speculations. There are always 20 more cartridges to buy. 
I can say from personal experience that Sound Smith will not re-tip the 17D3. Dynavector is the only place to send it/ swap it. 
@chakster The ART9 discussion may be old but not irrelevant. And just because one person replaced his with a cartridge over twice the price doesn’t mean it’s not a great cartridge. I replaced mine with one six times it’s price, yet I still recommend it. 

This is not about hype. That thread happened 3-5 years ago. People still go crazy over cartridges like the DV-XV1s and Koetsu, both which have been in the running for over a decade.

And if you read my initial recommendation, it was to also look for the ART9XI, which succeeded the original ART9 and is available today. And though I have moved on to other cartridges myself, I still recommend the ART9 or ART9XI. 

Regarding Dynavector, I also own the DV-XV1s and DV-XX2 MK2 in my collection. I think they are fantastic cartridges, and this isn’t a bash on Dynavector. 

Should the OP want to retip the cartridge, reach out to Steve Leung of VAS audio. He is a top notch guy, and his office is the next suite over from VPI. His retips are excellent, and I’ve had three carts done by him myself.
