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.

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.

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. 
Ortofon chart, for 20uN/mm:

total mass range 9-25g, ideal around 13g if I read the curve right.

Who knows the Mass of JVC-UA-7082 Arm _____?

Mass of Acos Lustre GST-801 Arm _____?
Neonknight made the right ''pre-condition'' by adding ''if functioning
properly''. I think that its lift is worthless, magnetic functions
unreliable and counterweights inadequate. Long instead of ''short''
such that they can be moved nearer to the pivot. To correct this
the magnetic VTF function should be removed such that the
counterweights can be moved nearer to the pivot. Aka ''manual''
VTF adjustment is better. I ''of course'' prefer FR-64 S.

mass of my 2 arms is not there, still looking for their mass ___?
........................

interesting how the null points vary for each arm, I've been using my Shure V15VxMR null template for all my +/- 9" arms. 

I just got this as a gift for Christmas, it has a grid to use that will help get any arm right

it's the thickness of a record which is nice when adjusting
