Hana ML and Korf head shell

Ooopsie 48 dB of gain.

The p77i compliance is 18, so it’s a ways away from the Hana at 10 cm/dyne.

1) Compliance for Garrott measured at 10Hz

2) Compliance for Hana measured at 100Hz (like for all Japanese cartridges).

If you convert 10 at 100Hz to 10Hz it will be 17cu (almost the same as Garrott), this is definitely NOT a low compliance, it’s more like a mid/low end (or you can call it mid compliance which is good for nearly all tonearms, except for too heavy or too light arms).

For any measurements you need to know a compliance figure at 10Hz (not at 100Hz). For Japanese cartridges it’s a bit tricky, you always have to convert to 10Hz first using x 1.7 formula.

@chakster Thanks.
What is your experience with required gain?

• That Audio Research PH2 is the SS model, and its manual says gain=48dB.
  
• That phono stage shows posts for resister loading, but a flashlight through the holey metal does not reveal them.
• It has balanced In/out and I have a handmade XLR to RCA, which sounds OK and read ~24k resistance, which sounds right for two 47k in parallel.
  

So I am reticent to order the ML until I know whether the phono stage will work, or if I need something else.The other options include the p77i (or the Hana SH) which both give me higher output.

Ahhh. I thought that it was purely a spring type of metric.

I sounds like the compliance is also using something like the mass of the cantilever/coils???
(But I would have thought that that was next to zero to capture the high frequencies in the groove?)

[Headed to Google]

You don’t need a high output MC (more coil winding increases moving mass, that’s bad), if you want an MC cartridge you need Low Output MC.
Gain should not be a problem, Hana is not the lowest output anyway, don’t forget that you might have an active gain stage on your line level preamp in addition to the gain of the phono pre.

My advice is to try Garrott Dynamic Coil P77i cartridge with user replaceable stylus. You will find one on Reed 3p tonearm in my system, effective mass of my Reed is 18.5 gr.

The P77i is listed as MM with an output of 4.0mV. 

Garrott Brothers P77i CartridgeMoving Magnet (MM) Phono Cartridge

• Output Voltage: High output type 4mV @ 3.54cm/sec
• Input Impedance: 47k

So the p77i appears that is HO and MM.
And the Hana ML is LO and MC.
(hence my confusion)
