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

Below is the answer from Doctor Noburu Tominari himslf for those who’re asking why top models comes with long Boron cantilever.

RG. "I notice that neither the XX1, the Te-Kaitora nor the XV1 use gemstone cantilevers. Why is that?"

Dr.Tominari (Dynavector Systems): "At the moment, the construction of this magnetic assembly used in these cartridges requires a long cantilever. It would be very difficult to engineer this for a short cantilever, and also very, very expensive."

Dr.Tominari (Dynavector Systems): "The Te-Kaitora is really just a special version of the XX1 made for Mr Denson who distributes Dynavector products in Japan and also builds the Dynavector electronics. It has no body, and uses better magnets and selected parts. And also better quality wires as well."
No model number anywhere and unfortunately no papers came with. The only information is a stamped little mark "1" on bottom of the aluminium part (base) of the wooden body. My sample may very well be re-cantilevered though. According to Hart Audio in UK this was made for the Japanese market only not US. And the wooden body is much longer and heavier.

Whatever the case, a modern MC AT- ART9 has nothing on it in audio quality when using stand alone fashion on the aluminium wanded Trans-Fi linear tracking TA. Tracking easily 90 um at 1.5 g actually it´s the finest (and flattest, excuse my clumsy expression) MC I have heard, in particular mids is very transparent and highs so refined almost sweet but my knowledge and experience in MC kind is limited.

I agree with Lew 's post from 06-30-20018 stating that ''exotic''

parts do not guarantee ''Nirvana''. But I will try to first make

our ''implicit'' conceptual presuppositions clear and than elaborate.

The first is the simple sentence form ''S is P''. The basic form

to ascribe properties to objects. The other is ''parts and wholes''

pre- conceptions. I think that we all can agree that without

comparison between cartridges we can't make any judgments.

However comparisons are relational  in logical sense while

''S is P'' sentence form is not suitable for relational descriptions.

Say ''brother'' is not some kind of property of an person but a

relation to some other person.

We can see that ''our'' chakster try to explain differences between

carts by their ''parts''. Say in the sense of Lew's ''exotic parts''.

He is very fond of ''diamond cantilevers'' which should be ''as

short as possible'' (grin) This is not my reproach but he admitted

to have an ''border line'' regarding cart prices. I don't believe

that prices have necessary relation to sound quality but what

we call ''the top kind '' are usually pretty expensive .Anyway

chakster limited himself in the sense of ''extension of his

comparisons''.  This limitation is , say, ''financial'' which is in my

case ,say, of less importance. So I was able to buy Allaerts

MC2 which provide pretty strong arguments against ''exotic

parts'' reasoning. There is nothing special by this cart in the

sense of ''parts''. The cart is conventional even old fashioned.

But look at its technical specs and you will not believe your

own eye. There is no other cart that can come close.
