TW-Acustic Raven 10.5 or DaVinci Grandezza??

Dear Luna: Independent that makes sense to match Raven TT ( I assume you own Raven TT and even if you did not. ) ) with Raven tonearm because Raven designers took in count this match " necessity " a tonearm main target is to give the right answers on what any cartridge could ask for.

Cartridge designs are not perfect and needs carefully set up parameters, between these parameters is the azymuth critical one that with the Raven you can change it as the cartridge needs but you can't do this in the Grandezza.

Now, if you don't care to much on what the cartridge set-up needs then you can choose any of two but if you care that your cartridge on this critical parameter set-up be on target then the 10.5 is IMHO the " road " to go.

Here stated that no-azymuth in the DaVinci:

The tonearm designed to matched the turntable ....?
Serious ?
If a cartridge has a misplaced stylus - i.e. the need for azimuth alignment to compensate that - give it back to the dealer for full refund or exchange.
Every US$80 DJ-cartridge is dead on 90° perfect azimuth.

You shouldn't ask for less from any cartridge costing any multiple.
There is good reason why some very respective tonearms out there - and some since 30 years .. SME V - do not feature an azimuth alignment option.
Why compensate something you should never accept in the first ?

Dear D:Please stop to say " stupid " things about. Btw, SME is not a " perfect " tonearm in the same way that there are no perfect cartridges and of course no perfect LPs and even no perfect cartridge set up by any one.

In the other side a 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. Till today there is no perfect solution to " one for all ".

Dear Luna: If I remember time ago you have experienced the help of azymuth setting/changes, so you already know its importance level to use it when is need it.

Your call.

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.
