Cartridge, Compliance, try what in my JVC UA-7082 Arm?

For options, I found and bought the optional extra counterweight, fits either 7082 or 7045

So yes seeing as you insist on being pedantic, you stated the OP has bought, all I did was correct that to a more correct "in limbo’ status which is 100% fact but no you still wish to contest the statement and have the last word! Have a good day, I am done smacking my head against a brick wall with you.

I have no idea what the F are you talking about each time when you say "last word" etc, instead of some useful contributions with facts, carts, links, data, pictures and everything i am doing here to help people, you’re talking about me "and my last words, brick wall etc". Please post something useful for everybody instead. The OP has bought another Victor system after he has canceled purchase of the previous system (because i have mentioned the problem with a counterweight which you can't even see just like Lew).   

It has original Headshell and Cartridge: Victor Z1s, not sure what Stylus is in it.

More important is to know long it was in use before you will put it on the record, it can be worn out already. The Z1 is the lower model from Victor and its styli are not compatible with the higher models like X1, X-1II etc. There are various styli made for Z1 (conical, elliptical etc). If you have the original for 4 channel then it must be Shibata and it’s the best for this model, it’s probably this one.

You can always change the original to JICO SAS just like Halcro did.

Z1s would indicate 'spherical'

found this who found that

" In searching for an answer to the above, I came across the following post on Audio Circle forum by a member whose screen name is griffithds:

All Z-1 bodies are the same. There is a Z-1, Z-1S, Z-1E, Z-1EB, Z-4 which is also a Z-1 and a few others.

All the same. All the stylus are interchangeable. But they are not interchangeable with the X-1.

The cartridge generators are very similar but they (Victor/JVC), changed the diameter of the tube that slides into the cartridge body so the X-1 and Z-1 are NOT interchangeable.

But they do sound the same. I own both and have to get up and go over to the turntable to be able to make a correct determination as to which one is mounted and playing.

That is unless you have the SAS stylus attached. No mistaking it when it is mounted. Also, when you order the SAS from Jico you can get the clear housing, the green housing or the orange housing. These are the different colors of the -1 (clear), the -1E (orange),or the -1EB (green), stylus housings. Exact same SAS stylus but just in case you want to stay with the same color of the 'Z' cartridge that you own, Jico supplies you with the option to buy the same color of stylus housing. The 'clear' housing is the color of the one that came with the Z-1.

Just for information purposes, the Z-1 was a Beryllium cantilever with a Shibata tip. The 'E' versions were Elliptical tip. The 'S' version is conical or spherical. The 'B' on the 'EB' version was E for Elliptical, B for Beryllium.

Hope this answers your questions. If not, then ask again because someone could write a book on all the variations of this Jem!"

Hi Elliot, You are making life difficult. The Japanese mostly design their arms around stiff moving coil cartridges. My guess is the arm has an effective mass somewhere between 15 and 20 grams which is too heavy for many moving magnet cartridges like the Ortofon 2M series. The Sound Smith Zephyr MK III is a low compliance high output cartridge that would work well in your arm. Down the line is the Irox Blue. These cartridges have a compliance of 10 u/mN which is perfect for your arm. You want something between 10 and 15 u/mN. The Clearaudio MM's are 15 u/mN.  Another important factor is the weight of the cartridge. Here is a graph that compares total effective mass (tonearm and cartridge) to compliance.

Just add the weight of the cartridge to the effective mass of the arm for the total effective mass and look where it falls on the graph. I try to shoot for a resonance frequency between 8 and 10 Hz. I think the bass is better
if you can get it down there.
