The Palladian-A step beyond


The new cartridge from Acoustical Systems may finally be the LOMC to fully realise the theoretical advantages of the genus.
And convince those long-suffering audiophiles to whom the 'modern' MC presentation has been anathema to 'live sound'....that the realism of vintage LOMCs like the SPUs and FR-7 series has finally been recaptured 👀

To keep this on track, Halcro, did you use a torque wrench on your cartridge screws?  The tension on cartridge screws can certainly affect sonics, for all the reasons you and others reiterate.  If one were to draw conclusions regarding the efficacy of this or that fastener per se, then I think torque has to be a constant.

Solong, it's fascinating that you have already done research on titanium screws.  Prior to now, had you drawn any conclusions?  Thanks.  I've just been using aluminum or plastic screws or anything non-magnetic.

Nandric, The best I can figure out  is that my post(s) were deleted because I used the word "virgin", in the context of re-telling a well known anecdote about Groucho Marx and Doris Day.  Since neither Groucho nor Doris will be reading this thread, I cannot believe it was because my post(s) might have offended them.  Moreover, those two would have laughed and probably did laugh. By the way, Doris is a much under-estimated chanteuse.  If you have the LP of her singing with Andre Previn, it's pretty good work.

Dear Lew, You must be totally wrong. A virgin or virgine ''attribute''

is  something that is very valueable. I kind of compliment . In particular by the Arabs each of them willing to give at least 6

camels for one. But if you agreed with Gaucho that Doris was not

a virgine this could be seen as an offense by the moderator.

Oh wise King Nikola 

Will 6 camels allow us to buy one Palladian ? 

Dear Chris, As far as I know Dertonarm likes blonde. So if you

have some to offer perhaps. But I am sure that he dislikes

camels because he likes to drink. A camel can endure 10

days without drinking. But who would like to be a camel?

You're quite right Lewm....
Here's what Dietrich recommends:-
If you happen to have a small torque driver to use, the set value to use (ONLY with our cartridges, as they do feature a thread in Timet 1100 material!!) is: maximum 0.85 Nm with M2.5.

Unfortunately......I don't possess a small torque driver so I had to just use the Allen Key supplied with the screws and was careful not to over-tighten 👀
After hearing the results with the Timet screws though.....I might invest in a torque-driver.
Interestingly....in the latest TAS, there is a review of the latest Brinkmann Spyder turntable where the Reviewer comments:-
Like many designers, Brinkmann prides himself on using subjective evaluations.
"Everything has an influence on sound", he writes. "And we have to accept that these influences are real - even if (for the moment at least) we have no scientific explanation. Each single part of the device, no matter how trivial, has an influence on sound. Yes, even the smallest screw"
Through careful listening tests he discovered that replacing one of the stainless screws that affix the cantilever in the Pi pickup with a titanium brought "sound that resembled the original most closely"

We appear to be learning more about vinyl reproduction....and at a faster rate....than even the great engineers and designers in the 'Golden Age' could have imagined 🤓
