SL1200GAE New Tonearm


Want to change the stock arm. Looking at a triplaner 9" vii any other one around $3500 new used . No preferences in particular.

did you position the arm on Norberts table just so the wire would miss the hinge? I was wondering about why the arm is shifted to the left so much?
If I recall correctly we made the arm board for his machine but Tri of Triplanar actually did the mounting and setup.
If you position the arm correctly, yes, you can use the lid. You can't do it with the 12" though :)
unfortunatelly my dialogue with atmasphere was and is from a way different subject.
That is true - mostly an apparent lack of decorum on Raul's part.
^^ If you want to say stuff, you have to make sense.
You've presented nothing in the way of argument to back your position, just personal attacks and accusations based on nothing. You need to up your game.
Problem is that atmasphere is a seller and always post to promote something of his busine$$.
@rauliruegas I'm calling BS on this. Every Triplanar we've installed on SL1200G 'tables was shipped to us by the customer. Get your facts straight. 
 Cannot see how it can get much better and I have heard some great tonearms.
As I have mentioned, the stock arm is as good or better than many 'high end audio' arms. It could be playing bass better though and could be a bit more neutral (the arm tube talks back to the cartridge a bit).

@pryso FWIW, Atma-Sphere was established 42 years ago as of August of this year.


Yes, maybe I can be more mind-calm with out removable headshell additional connection joints but this is not the whole history as it’s not what the you say about the bearing plane where it’s extremely important for unipivots but with the solid Technics tonearms that is BS.
Its simple. The bearing *style* isn't the issue. Think about two people carrying a couch. On level ground, they both carry the same weight. Going up stairs, the one on the bottom carries more.

If the tone arm has the bearings in the plane of the LP, the weight on teh stylus remains pretty constant with bass and warp. But if the bearing is higher, the tracking force diminishes faster with bass and warp. This is easy to prove out with geometry and is why arms like the Triplanar, SME 5 and ET are set up that way.  Some arms (like the old Fidelity Research) attempt to solve this by designing the counterweight to hang below the arm tube (which the Technics does not do, but would be an improvement for that arm) but this is not as effective as placing the bearings in the right place to begin with.
 
Ralph, So sorry that I volunteered you for TP questions. That was unfair of me. (I think maybe that was why you wrote, "sheesh".)
No, it wasn't, and no worries.

would like not to drill into the plinth though. The arm I got is from John I think you know him.
@jtsnead , there's no need for that- if done correctly, its all reversible with no evidence it ever happened.

" Want to change the stock arm. ", what's wrong with. What do you do not like?
The gimball bearing on the Technics arms is really very good design and your GAE tonearm is made from magnesium that's similar on some of the top SME build material.

The stock arm is competitive with many high end arms.

But both the Triplanar and the some of the SMEs have something on the Technics arm, which is that the bearings are in the plane of the LP rather than the arm tube. This allows for more consistent tracking force in bass passages and negotiating warp. It makes a difference as to how well the arm can play bass. The Triplanar is far more adjustable, and has much harder bearings; VTA can be adjusted on the fly, and the arm tube is damped for less coloration. A removable headshell means that there are more mechanical connections, which can degrade the sound when dealing with very small signal levels. That is why the SMEs and the Triplanar do not have a removable headshell.
Sheesh.

OK, we've done several SL1200G (or GAE) machines so far. Both the Triplanar 12" and the 9.5" arms can be mounted. I recommend replacement of the platter pad as well. We fabricate a special armboard; the concern is that the rigidity of the plinth and subchassis must be as rigid and dead as possible, so that if the platter is vibrating in some plane, the arm is also moving in that same plane so the noise cannot be transduced (the principle behind our model 208 turntable as well).

Most of the armboards I've seen aftermarket don't address this issue and so might have a bit of coloration.

The finished combination is spectacular. Technics really did their homework on the new SL1200.
