Any Love for the Grace F10 L Moving Coil Cartridge

Just picked up one of these super rare cartridges and wondered if any of our members had ever owned one and if so could offer any feedback on what to expect.

I had convinced myself that I would not buy any more cartridges and had actually being selling some off to pay for a rebuild on one of my most valued cartridges. Unfortunately for me I have a weakness for those very rare vintage cartridges and I simply can't stop myself if one becomes available at the right price.

The model I have coming is the "L" version with hollow Boron cantilever (hollow boron is another weakness of mine). The specs are as follows.

  • Frequency characteristics: 20~30,000Hz±2dB
  • Output voltage: 0.75mV(5cm/sec, 1,000Hz, 45°)
  • Impedance: 23Ω±10%(1,000Hz)
  • Channel balance: within 0.5dB(1,000Hz)
  • Crosstalk: below -25dB(1,000Hz)
  • Stylus tip: 0.2×0.8mil Advanced Luminal Trace
  • Stylus pressure: 1.8gr (±0.5gr)
  • Compliance: 20×10-6cm/dyne
  • Cantilever: Boron composite
Like my other posts, I will report back with my own findings for those who stumble across this thread in the future.

Thanks.

Thanks dgarretson, I presume the compliance is measured at 10Hz and not 100Hz like Audio Technica and Denon.

@ateal 

they are all measured at 100Hz, Japanese style. 
Grace are high compliance cartridges for lightweight tonearms.

Thanks Chakster, that makes this one super high compliance with a converted figure of 36. That’s quite a bit higher than the Grace MM’s such as the F9 Ruby and Grace Level II. 

What I find odd though, is that the mid point VTF is quite heavy at 1.8g. Normally super high compliance carts have average VTF’s of 1 to 1.25g.

Looking at the specs of my signature Grace Asakura’s One MC, which is twice as much in price in the old catalogs, i see the same 1.8g tracking force recommended, but the compliance is 15 @100Hz, which is about 25cu if we convert it correctly to 10Hz. Yes, it’s very high compliance for LOMC. Another high compliance LOMC from my vaults is Ortofon MC2000 (compliance 20cu, recommended tracking force 1.5g). So they are close, great trackers!

Thanks for the additional info Chakster. 

The F10L at 8.6grams in weight plus the included Grace HS-6 headshell at 11grams and a compliance figure of 36, sure make it challenging for tonearm matching. 

Not sure what arm to put it on.
