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.

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
Regarding your Victor UA-7082 you can just remember that an optimal Victor top of the line cartridges designed for use with this arm on stock lightweight headshell are as follows (for example):

1) X-1IIe (MM) own weight is 7.5g, with stock shell, wires and screws it’s about 20 g.

Dynamic Compliance 12cu @ 100Hz (*please note than a compliance @10Hz will be at least 20.5 cu)



2) MC-1 (LOMC) mass 8.7g, with stock shell, wires and screws it’s about 21.2 g.

Dynamic Compliance 8cu @ 100Hz (*please note than a compliance @10Hz will be at least 13.6 cu)


So i think you can use any cartridge on 12g headshell with dynamic compliance from 13cu to 22cu @10Hz according to Victor philosophy. There are low and mid compliance cartridges! For higher mass headshell/cartridge combo with lower compliance cart you need a subweight for the arm.

I don’t think you will find any headshell lighter than 9g for use with higher compliance cartridges.

Buy Hi-Fi TEST LP to measure actual resonance with your own arm/cartridge if you’re so worry about it.

Many online calculators are incorrect, you’d better use a record to check tonearm/cartridge resonance, you will see when they are shaking.


P.S. And stop buying mediocre cartridges if you really want to hear the potential of those tonearms.





I think that its lift is worthless

I've seen two different armlifts made by Lustre for 801 series. So they tried to improve.
