Tonearm ...... Acos Lustre GST-801 ..... Yea/Nay


Acos Lustre GST-801, claim to fame is magnetic stylus force and magnetic anti-skate.

Hopping about, getting ready to pick the rear arm of 2 arm deck. Use for existing Shure 97xe and V15VxMR, both with their dynamic stabilizer brush, and AT440ml (no brush), and NEW Mono Cartridge.

Joe Grado says OK for his Mono Cartridge ME+ with both JVC UA-7045 arm and Acos Lustre GST-801.

"it should work just fine
the compliance of the ME+ is 20cu"

how do you compute from 20cu to _____ mu/mN???

Testing my skills, especially anti-skating.

I ran test records today,

Stereophile LP ..., Shure V15 torture test LP, ... Denon Demo LP...... I skipped my 4th, whatever it is, it's downstairs.

Anti-Skating test matched my TT dial (I don't trust them) and my ears, that was nice. I'm looking forward to the GST-801's Magnetic force controls.

My Shure 97xe on Audio Technica AT120 arm only hinted at a speck of resonance at 11hz. Tested it with Dynamic Stabilizer in and out, no apparent difference.

Tomorrow I will test the AT440ml, no brush, see how it does.

It's the same
Most important is to know how it was meassured (at 10Hz or at 100Hz)
cu = mu/mn 
Happy New Year Everyone, and thanks again for all your help with this exciting project. 

I will ask Grado what frequency.

I just tested my old AT440ml cartridge. It's wonderful on clean records, toooo noisy on used ones I acquired along the way. 

Maybe I should buy a shibata stylus for my Shure V15Vmx, it has the brush which helps with static, probably why my 97xe with brush is quieter on older LPs.  I'm guessing any Shibata will be the same, wonderful or too noisy.

But first I need to see how these cartridges pass the resonance test with either of my new arms that are coming.

With a digital stylus force guage, rather than Shure's see-saw, it is easy to change head-shells and reset things, and this TT's dinky anti-skate turns out to be accurate.

using these 3 guitars to help evaluate sound, and anti-skate imaging results as well as test records.

This one is awesome also

As always, go from CD to LP, people choose the LP. Go from SS to tubes, people choose the tubes.
Happy New Year!
Grado is American manufacturer, so they are measuring dynamic compliance at 10Hz, but nearly all Japanese manufacturers measuring at 100Hz.
