TW-Acustic Raven 10.5 or DaVinci Grandezza??

Dear Lewm, these shots aren't digitalised yet, but I will try my best and send you a few shots by PM in a few days.
And - oh, yes ... you will clearly see disproportional wear on one of the stylus.
BTW - due to "azimuth adjustment" ......

No, I can't tell by mere eyesight whether a stylus is 90° dead vertical.
And I haven't stated in this thread that I can.
That's why I conducted a survey.
In general - in general ... - it no longer a problem today in NEW cartridges.
But get a cartridge from "demo" or used and you will find a hell of a lot with displaced/disorientated cantilever due to erratic applied anti-skating and/or disproportional worn stylus.

Hey Dertonarm, do not get it so seriously - just a joke.

I'm not surprised. If the probleme again is in the reading, it is not there. Apparently the problem is in the writing.

I'm not in any "fan-groups" (unlike somebody here)!!

I have absolutely no interest in azimuth - no matter with or without fine calibrated scale !!

So, to return to the Lunas question - TW-Acustic Raven 10.5 or DaVinci Grandezza?

Your answer is: "The DaVinci will be a future classic - for design and performance and is THE single component which has put DaVinci on the map."

My two cents - Yes, but this future classic single super component has very short life - it is out of production !!

Best regards,
Lyubo

Dertonam,

Just a quick note to say thank you for your input. Whilst we all may have differing views, your posts above raising the questions on coil output, electrical behaviour and stylus alignment vs asymuth are thought provoking and add significantly more to the discussion than comments such as "blah blah blah" and he said/she said type arguments.

Thanks again for taking the time to explain your views, some of us appreciate that.

Dear Dover: Are you serious? how is that a 20+ years " professional " high end audio distributor today " discover " " coil output/electrical behavior and stylus alignment vs azymuth ? what was or what kind of support and advise gave all those years to your customers? no one asked?

Regards and enjoy the music,
R.

Hey Raul,
I know heaps, I've forgotten heaps and I'm sure there is always opportunity to learn more. What's wrong with thanking someone for putting time and effort into explaining their experiences.

By the way with regard to the RIAA curve, since you are a manufacturer of phono stages, the comments I made on an earlier other thread were slightly askew. The RIAA standards require amplifiers that drive the cutterheads to apply compression and expansion above and below 1000hz. The engineers could not build amplifiers in those days to do that and In actual fact you will find the turnover points are actually around 400hz and ( I cant remember the figure ) but around 4000hz. This means for accurate reproduction of RIAA recordings you actually need a flat midrange at around 400hz to 4khz.
As stated earlier I have a mathemetician/engineer mate who has modelled this revised RIAA playback in an op amp based phono stage ( not your normal stuff, the op amps used are next generation designs not yet available to manufacturers ) and the organic wholeness of the midrange is revelatory.
Ironically you could drive the cutterheads far more accurately today as regards RIAA compression/expansion with digital amps.

Cheers,
