TW-Acustic Raven 10.5 or DaVinci Grandezza??

...TT designer that want to design a tonearm for at least take in count an arm board that match the tonearm build material resonances to avoid adding more. This designer knew perfectly the tonearm behavior about so he can help in better way with his tonearm design that with a different tonearms where he almost know nothing

Not true. Some (not all) always think, when a "Designer" does something, it is automatically prefect, well done and a lot of brain is inside. I think, this is a master mistake in audio today. Every new "Design" gets its merits, some don't hesitate, to name it a "great" design when a piece of wood for 10K is offered, but each his own...

Till today there is no perfect solution to " one for all "

Not true. But again, each his own, when someone has no technical knowledge or fixes his view on the wrong technical issues, well, then nothing will be ever done right.
Sometimes electronics can show the differences, sometimes not, sometimes the listener can understand what he hears, sometimes not...it is not a religion, but of course are some design existing, which have some better solutions.

Raul,
Have you even heard the Raven 10.5 tonearm?
If not?........how is it possible for you recommend this arm?
Are you just trusting that it is better than the DaVinci?

Dear Halcro, Raul had to favor the Raven by all means.
Why ?
Simply because I favored the DaVinci ....
It always works this way.
I for one would NEVER accept a cartridge which needs azimuth adjustment.
Cheers,
D.

Dear D,
I agree with you entirely.
I have rarely had a problem with the azimuth of cartridges when used on arms without azimuth adjustment.
However on the two arms where I DO have azimuth adjustment........the Copperhead and the Micro Seiki MA-505......I have to battle with it.
Particularly on the MA-505.
The DaVinci is virtually assured to be spot-on with azimuth....unless your cartridge is a 'dog'....as Dertonarm says :^)

I don't want to enter the debate here about the merits of either tonearm mentioned by the original poster, but I am surprised to read that there is a consensus shared in this thread that azimuth adjustment is apparently a completely perfunctory and unnecessary feature of tonearms. So am I to understand from this that adjusting cartridge azimuth is never needed because all manufacturers ensure cartridge azimuth is perfect at the factory?

I guess all these third-party devices like the Fozgometer and the new Soundsmith Cartright product are redundant and not needed. I, for one, am relieved to learn this!
