Dynavector cartridges, old and new


For more than 40 years Dynavector has been producing very high quality moving coil cartridges in Japan. Sadly we don't have a dedicated Dynavector thread here on audiogon. It would be nice to collect info about some nice rare models in one topic. 


My first Dynavector was high output model, very attractive headshell integrated as one piece - Dynavector DV-30A was released in Japan 1 year before the Karat series and 4 years before the fabulous Karat Nova. The first high output Moving Coil Dynavector DV-30 series was the next generation of the Ultimo cartridges. The Ultimo’s were manufactured by Onlife Research Inc., which later became Dynavector. The 30-series was introduced in 1978 with 3 different models DV-30A & DV-30B (HOMC) and DV-30C (LOMC). Till the early 80s it was top of the line Dynavector models.... 

But then the KARAT was released with short Ruby and Diamond cantilevers (depends on the model). I've been looking for KARAT for a long time, i found the Dynavector KARAT 23RS special calibrated version with Micro Ridge stylus tip and prism Ruby cantilever. This particular model has been introduced in 1988 and claimed to be superior to the earlier generation of Karat carts. I'd like to seek more info about this rare cartridge, but very little info available online. Anyone can comment on Karat Ruby 23RS mkI (not mkII) ?  

I know some mebers are enjoing the more expensive Karat Nova series, XV-1, XX-2, Te Kaitora Rua etc 

Modern Dynavector site is: http://www.dynavector.com/ 

But the rare models can be found here

I had Dynavector 10X4 in the ’80s used for a long time, the sound was good and I was satisfied but the improvement was when for the pleasure of trying I removed the red casing ... the sound improved considerably leaving me impressed; at that time there was no talk or very little was known when the casing of cartridges was removed and the sound became better.

Since then it is possible to remove the casing from the cartridges I use.

Saw something interesting on the spec sheet for the 17D3; the internal resistance is 38 ohms! This means don’t use the standard 100 ohm load that one would normally use for an LOMC with 0.3mV output. It also means that the 17D3 has relatively large coils and relatively weak magnets. I am in no way saying or thinking that these numbers predict mediocre sound quality. As I recall, when it was introduced, the 17D3 was something of a giant killer at its original price. I still have not auditioned mine, which has very low hours from new. (It is from the estate of my dearest audiophile friend; I was consulted on his decision to purchase it, although he was at least as knowledgeable as I will ever be.) I actually heard it on his system once or twice before his symptoms of dementia became very advanced. We both liked it.

I would load mine at no lower than 1000R, maybe 47K.
Chakster, how do you load your 17DS? 
 

I can't remember, but most likely i've tried 470 or 2200 on JLTi phono stage with that Dynavector. 

BTW with my Ortofon MC2000 i use only 47 Ohm on the Gold Note PH-10 phono stage, because recommended load impedance for this cartridge is 20-100 Ohm (stated in the manual). Cartridge internal impedance DC resistance is 3 Ohm.   
I just ordered a Dynavector Te Kaitora Rua and curious about retip options for the future.

Was looking at the Sounsmith Sussuro, and while I have enjoyed their carts in the past, I wonder if the high price tag reflects the smaller outfit and time for production etc. given it is a small shop. Not saying price = sound but I've always wanted to try this Dynvector having never owned one.

Let us know what you think, must be a great cartridge 
The only problem of those Te-Kaitora and X-1s Dyna cartridges is unprotected cantilever which is so easy to destroy assidentally. Some other carts on the market from various manufacturer have the same problem, personally i would never buy any of them for this reason. I feel better with conventional design, when the cantilever is under the cartridge body and protected from left and right side a bit better.
