Yes, you are right, CD -4, i have no real experience with quadro, i have only one quadro record, the *darke side of the moon *, pressed by MFSL and somewhere i have a cartridge with Shibatatip, never more touched sind more than 20 years.

@bear
I do not fix cartridges, but i have seen a video of german rebuild, using such a small wheel saw. I think there are also other methods, but the specialists don't share their secrets.
Using glue is usual to fix cantilevers into studs.
BTW, specific mass of diamond is 3,5 , Ruby and sapphire 4, versus alu with 2,7.
:D

I also dont know how to drill holes in such a thin alu tube, but in 1960 they hardly had Laser driller, so it must be possible to do it mechanical.

@avwerk
MC wires are usually between 12 and 30 mikrometer in diameter, some guys use gold wire. Stupid, gold has the highest mass of all wires. Silver is not light as copper, but close, some people find silver better.

I have a Micro Magic * Magic Diamond* , working on Goldmund Reference Table with Goldmund T3F Tonarm with Servocontrol and a EMT 930 ST Turntable with Thales Simplicity, carrying a Micro Magic *Silver Spirit*. The EMT Set-Up sounds closer to the Master Tape IMHO, but is somewhat sensitive for extremly warped records and extreme subsonic feedback. Thats maybe 1 record out of 300, so i can live with that and listen them at reduced level.

I used several very expensive Kisekis, Koetsu, Grado and whatever, since i discovered that spheric tips rules , i stopped searching and listen music with a lot of pleasure.
The DL 103 was a very good compromise for the money,there mus be a reason that it is built since 50 years. It works only with heavy arms, i still have a FR 64 Steel and a Lenco L 75 Idler wheel Table, waiting to get married...


The Micro Magics are also expensive, but due the spheric tip they can do up to 6'000 hours and the maker offers a perfect service. The Magic Diamond is in use since 10 years and needed one service to remove magnetic dust/dirt from gap, thereafter it was like new.
 
Yes, the Magic Diamond has a Blue Body.

I am a Hi-Fi Dealer in Switzerland, so i am sitting at the source for MicroMagic, but i do not want make advertisment here.

Both Set-Ups are in my private hands, since i love listen music from my record collection.

My Intention is to get more information how Cartridges are made or have been made( just for interest, not to make by myself) and share my knowledge with interested people , who wants listen music from records and because most of the knowledge from the vinyl aera is lost and deserves to get a revival to avoid fairytales told by stupid Bling_Bling Salespeople having no real clue how those thingies work.

Basically there are some physic laws and euclidic geometrie, which are still actual.

Record cutting machines and the whole process to make a record is basically precision work paired with knowledge and still wonder why it works so good for my ears, because it has so many problems to be overcome and it is not perfect.
 
You have to congrat to the maker, i just bought them. :D
It is real Swiss Hand Made and everyone of them is made like a perfect clone of the others.

Would like to know how it is done, but the maker has his secrets i have to accept.

I just know, that the tips are grain oriented, double polished, coils wound with counted winding numbers and every alignment lesser than 0,5 degrees error and very stiff suspension, body weight is 14 gramms for the Magic and 25! gramms for the spirit, both have a solid metal body with threads for the screws, use spheric tips and need apx 2,2 - 2,5 grams tracking weight to work proper, antiskating is not really necessary, with my arms anyway useless.

Generally spheric tips with correct radius tips are much lesser sensitive to scratches on the surface and dirt down in the groove, so they track pretty quiet.

Tonearm

Simplicity ::: Thales - the one and only tangential pivoted tonearm

This is the arm in use, basically standard version, but i has an extra heavy counterweight for the Silver Spirit, so the Resonance is apx 9,5 Hz.

There are copperbars between Cartridge and Headshell and brass screws tighten just as much as necessary to achieve best decoupling from arm for clean and open reproduction, this trick works also very good for the Denon DL 103, especially if you have a modern arm with lots of damping.

The arm is lifted backside apx 3mm to achive most correct VTA with the spheric tip and the Phonostage has variable RIAA Compensation to achieve correct frequency response with old records, the connection between arm and Phono is balanced with XLRs, since the Phonostage FM 222 is really balanced.:cool:

Very nice, I love thre is a lot of space to connect the cables between the cart & the tonearm. FM products are very expensive, never heard one but are very famous and ultra high quality.

Could yous post a pic, I want more details because I use Linn Ekos medium mass.
 
copper bars

Silver Spirit 003.jpg

Here you can see the copperbars, the DL 103 has not such v-shaped slots, but you can simply lay them on top of your cartridge and tighten brass screws just until you feel resistance. Lift your arm also 2-3 mm and since its medium mass, add a piece of 5- 10 gramms of lead on top of your headshell and readjust the weight.

Brass screws are important, since they are non magnetic, well damped and somewhat soft and thus easy to tighten them very carefully.

You will find this lead weight at your local car tire shop for the price of a chewing gum, they use them to compensate wheels which are excentric in weight. It has an adhesive to install it fix when you found correct weight.

The old dusty record is just my dustprotection for the EMT, since it has no dust cover.
