This is my first post here, so bear with me if my set-up isn't as sophisticated as yours.
More and more as of late I started to notice that records exhibit surface noise that was less pronounced [or absent] before. I bought this cartridge 5.5 years ago, and it has been in service ever since. I would estimate that it has about 1,000 hours on it, perhaps more. It still tracks fine, and I don't hear any other signs of ageing aside from the increased surface noise. Do you think it's time for a new one?
I would like to stay with the HOMC cartridge because my premplifier does not have the LOMC transformer installed [it's a $500 option from the manufacturer which I hasn't excercised yet].
BTW, do you know whther Dynavector has a trade-in policy?
Here's my set-up -
Nottingham Analogue
Roksan Tabriz arm
Juicy Music Blueberry Extreme preamplifier
300B Set amplifier [home-brewed by a friend]
Klipschorns
Mostly listen to jazz music.
Thanks.

Dmitry,
I have no idea. I always felt that Dynavector 10x4 is some kind of rock-in-roll cartridge and never had it. Still, it $200 cartridge, or way sub $200 in Japan, and it should not be a big deal to exchange it if necessary. The surface noise might be picked from many reasons not only because the ageing. Check out all you setting on your arms and cartridge. This time of the year is very “peculiar” for analog as the temperature outside drops and heating kicks in. It affects average room temperature and humidity and I have see as some of my arms, particularly with liquid damping: changed their sound. Regarding the ageing – I never was able to tell defiantly if a cartridge has signs of warring, and partially in context of jazz music. The only objective factor that I recognize is looking at the needle at 500x-700x microscope and to see if the actual profile of the needle’s tip was changed and it I was then how much. You can get a microscope on Ebay for a couple dozen of dollars.

Romy,
Thanks for your reply. I thought 10x4 was in the $400 range. No matter, I'm thinking of changing it for something a bit more substantial, like another Dynavector. Do you have any experience with their 20X-H high output MC cartridge?
As I said before I don't have the LOMC transformer in my preamp, but it's an available option from Mark Deneen of the Juicy Music.
Do you have any photos of what a worn out stylus should look like under the microscope?

I second advise on microscope purchase. I went recently with my Grado Sonata to a friendly Audio Dealer who carries analog for many years and he said that he never saw a worn down stylus. He saw only damaged ones. He stated that it is like with cars oil change .Manufacturers of oil want us to change after every 3k miles when we can easily drive 15k miles on that oil. (I have to add that this dealer listen almost exclusively to jazz )Regards. W

Dmitry, if you can then can you name your posts identifiably, if would not be difficult, would be?
Regarding the subject. The signs of wearing would be different on different profile types. Particularly it is different for each needle on the contemporary “complex” profile. The only know to me way to assess the wearing of the complex profile is to have a reference point how the given needle looked when it was new. With elliptical or conical needs it is simpler but still you need to see under the scope a “progress” in order to recognize the “result”.
Still generally, a needle while it runs in grooves with time loose its cheeks, inappropriate antiscatting screw one side more and another less. Eventually the bottom of the needle become too “skinny” and the needle “sits” deeper into the groove, scratching with its tip the bottom of the groove. This is already a terminal state of the needle and it should be replaced long before it reached that condition. All other answers are possible to get only via a microscope… Rgs,
Romy

I think that a stereo type microscope is the choice for looking at 3-D objects, because at that level of magnification a standard, single barrel unit has no depth of field.
Best regards,

I'm about 60 miles away in Rhode Island, obviously we don't have any dealers here; Boston seems the best bet. Do you know of any dealers in Boston who carry the Dynavector line?

No, I do not. It is not because there are not but because I do not know. There are not reasons to buy cartridges from dealers as there is no cartridges serves that might come from dealers. Have you seen any dealers who would lend you a cartridge to try? So I do not feel that it is necessary to pay 40%-70% of the dealer’s markup juts because they move the cartridges box form this shelf to UPS. I buy my Japanese needles in Japan what the street price is way lower. Your Dynavector there should cost sub $200. Predicting your questions about the source – there are many, search and you will find.

I'm shopping for a Dynavector DV-20X High Output MC. So far I've only been quoted $580 - 20% trade-in for my existing DV-10X5 cartridge = $460. But if I could get it cheaper, especially much cheaper, from an over-seas source - I'm definitely interested. Which source in Japan would you recommend?
Thanks!
