High End cartridges and the built quality

Hi!

Someone ask me about how i made this pictures.
I use a Dino-Lite AM-4815ZT. The pictures with the crosshair are made on a CNC milling machine with optical lense.

Pictures with this quality are possible:

Back to the problem with the cantiliver/diamond allignment.
I also had two Audio Technica cartridges which had a azimutfailure of 2°.

@Whatthe
I wrote it, a Dino-Lite AM-4815ZT.

@Syntax
I was very dissapointed about the fact, that i have a 3000€ cartridge with a 4-5° twisted diamond.
What is the sense about exact adjustment with such a diamond?

(sorry about the english, i am german)

No problem Melm, ich do not earn my money with these pictures.

Hi Whatthe,

i talk about the tracking ability of the groove in µm.
A time ago Lyra talks about min. 60µm
Today i do not find this secification on their internetside anymore.

The tracking ability is declared in horizontal and vertical direction.

Thank you Cantgetnosat for the information about Melm!
I understood it wrong.

Hi Whatthe,

i had problems with the Kleos, because it tracks only 40-50my lateral and playing loud sibilants.

So my dealer send it in the warranty time to Japan and after it tracks about 70-80my. Certainly the compliance was to high for my 12" Reed 3P.

At this time i got a Skala from a friend and looked it under the microscope, because he had problems with it. After i saw the crooked diamond i had a look at my Kleos and was horrified.

I wrote an email to my dealer and Lyra Japan, but got no answer of both.

The problem is that the diamond is glued askew on the small plate you can see here

Apparently Lyra does not look at the diamond when building it.

Now i have a perfect built EMT JSD 6. All is perfectly aligned.

I think every manufacturer of those highend cartridges has to make a measurement report for it like EMT.

I do not want to make Lyra bad. The have very well produced cartridges. See here

I think it is not so difficult to align a diamond within 1 degree. The problem is, nobody of us users was interested in this case and we have payed the money. I earn my money with milling miniature pieces for aeronautic. If i have such tolerances, i really would have a problem.

Whatthe, what do you mean with this question?
Parrotbee, i know Chris Feickert very good. The programm i measured the azimut is from him. I know he selected the good Ortofon´s and send the bad back. He is a very pleasant man and i am very pleased with a Blackbird.

Hi Downunder,

i have made only one picture. I had alligned the headshell with a pencil lead to adjust the VTA and verified the SRA with the microscope.

If you don`t trust my words, i can make some pictures of the EMT.

On the second picture of you link, you can see the diamond is a bit twisted in azimut, but it is absolut acceptable.

The important picture frontal to the diamond he doesn`t make.

After the first repair the warranty was expired and i contacted my dealer and Lyra Japan. I got no answer to this problem from both.

I hope mr. Carr is reading here and he reconsiders the quality management.
