Looking for tonearm inspiration

Dear @rpeluso : These are the correct alignments parameters you need to make to set up the 308/cartridge ( either: Löfgren A or B. ):

Forgeret about the mounting parameters SAEC has, is the worst alignment for any cartridge.
So you need to mount the 308 as it was the first time but with either of those parameters in that link.

Rauliruegas, what exactly does, "a BS of design." mean? I think there is a slight language barrier here. 
The Modern SAEC 4700 is a static balance arm whose vertical bearing is above the plane of the record. It has an archaic dangling weight for an anti skate devise and it weights a ton not to mention it costs 13 large.
There are tonearms at 1/2 the price that are superior in all ways.
The SME V is far superior as are the Origin Live Enterprise and the Triplanar not to mention any Schroder or Reed tonearm. For anti skating the SME uses a spring. The Triplanar and Origin Live arms use a lever and the Schroder and Reed arms use a magnetic system. The best arms are neutral balance and have their vertical bearing in the plane of the record. The Kuzma 4 point arms are also excellent arms. Much superior to his earlier efforts. A neutral balance arm will exert the same VTF over warps and different thicknesses of records. A Static balance are will not.
As you raise the record surface a static balance arm increases it's VTF as it tries to return to it's balance equilibrium point.

I have to say you that I owned the two SAEC top models in its catalogue: 506 and the 8000.

Oh Raul, Atmasphere did answer your question. You just did not like the answer. He told you that the specifications of the Triplanar's bearings were not available to us as they are used in military gear and none of us have clearance for that information. It is a military secret. My brother does defense work and has that clearance. If you leak any of that information it is the end of your career and you could even wind up in jail!

The 4700 is the same SAEC 407-23 model and any of those tonearm manufacturers you named could envy the SAEC quality building levels.

Btw, the SME 3012 tonearm uses that same " archaic " anti-skate mechanism and I have to say works really fine but I name the 3012 because in the last 2 years is considered byt top system audiophiles as one if not the best tonearm out there.

Tango is a Thailand based audiophile whom own not one but 3 American Sound TTs where has mounted around 8 tonearms 3 are the 50K+ SAT and 3 the " archaic " SME 3012. He owns several cartridges as: Goldfinger Statement, Opus 1, top VDH, Etsuro and the like and you know what: he prefers the 3012 over the SAT ! ! ( I think his sytem is over 500K+ easily. )
