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

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.

From memory and I may be wrong right now I think the OP requires a fairly high output cartridge due to some issue with his phono stage.
I think he said around 4mv which is very high and would likely only be served by some vintage mm carts and possibly some Soundsmith carts.

Elliott can you clarify on this and just what is the phono stage problem if this is so.
Thx

The preamp has hum that starts just above my max listening volume, so I need to get a mono cartridge with high enough output, Shure 97xe gives 4.0mV now. so I wouldn't go below 4.0mV for the new Mono cartridge.

I'm gonna take the preamp to McIntosh in the spring when I visit my photo friend who lives 15 minutes from their headquarters in Binghamton, NY.

Guess my memory not so shabby.
I know this is referring to a mono cartridge but it has to be the same phono stage?
Or not possibly.
Is this still the situation Elliott?
If so it is probably really going to dampen your new table performance.
Spring is a long way off......

Well,

I have tricky ways to avoid pushing the preamp volume up to hum zone. With current 4.0mV output, the hum starts just above my preferred maximum, that is why I am looking for high output, equal to 4.0mV.

alt. use 1. Current. 

TT  to McIntosh tube tuner/preamp mx110z (thru preamp for it's wonderful Phono EQ), Then preamp to Cayin A88T tube amp, via Cayin's 'preamp in", (just a thruput). Volume is from McIntosh preamp.  Volume limited by hum.

alt use 2.

TT to preamp for it's Phono EQ. Importantly, it has 2 MM phono inputs. I will use 1 for 12" stereo arm, other for 9" mono arm.

Then, the difference, plug the preamp into any Cayin amp line in, get volume from Cayin amp, no nooise of any kind.

alt use 3.

Now possible, using current TT (won't be option for TT81/7082/7045).

This would work until I have the preamp overhauled.

Audio-Technica has built-in phono preamp. I use it, go straight to Tube Amp, skip going thru McIntosh preamp.

In spring get preamp overhauled by McIntosh, solving hum.

................................

As I say, with 97xe 4.0mV, the hum starts just above. If I get lower output, then we get into hum territory.
