Linn cartridge on Aro

Posted by: mmhifi on 25 August 2002

It's known Linn carts on Linn arms(Ittok,Ekos) have to be mounted "Linn tight". Can somebody explain physics of Naim's suggest to "finger tight" only mounting of the same carts on Aro?

mmhifi,

I did not know Dev is a spokesman for Naim.

In addition, I think you're reading selectively. In 1 of the 2 citations, the culprit is over- or under-tightening.

Look at the assumptions you've made in your entries in this thread.

How about reframing your query to cast light on a subject, rather than heat.

And why not use your name?

1. I am afraid of KGB.

2. Some of you, folks, certainly work in KGB. I see it by your friendly style and religious blind following of certain ideology.

3. I love heated sessions: music is all about emotions and involving factor, isn't it?

4. Maybe somebody can answer something normal on my question? I loose hope...

In my KGB manual it distinctly says to avoid using a hi-fi forum to gather intelligence since such forums are, at best, a source of disinformation and, at worst, of misinformation. wink

Just a thought:
Once the coupling between the cart and headshell is tight enough to stop things rattling or working loose, the tightness of the screws may affect any resonance in the coupling between the two. The response of a unipivot arm and a gimballed arm may be sufficiently different so as they work better with different frequencies fed into them.
The above is pure conjecture, the obvious thing would be to suck it and see; try incrementally increasing the torque of the mounting screws and listen to how things change.
Linn's explanation for needing tight screws may just be a theory to explain an observed effect.

Joe, can I copy your KGB manual to my Mossad manual?

Lo, thank you, I certainly will do experiements
with tightening. My dream is to get something
from Naim but...

mmhifi,

1. Yes, you did open with what appears to be a question. What sort of answer are you looking for?
You seem more interested in asserting that someone doesn't know what s/he's talking about - but you don't provide valid quotes. I understand your question, but I still don't know where Naim suggests finger-tight mounting of carts on an ARO.

2. What is the goal of a heated discussion? Again, I'd rather cast light on a subject than heat. And how exactly is a hetated discussion related to music? Is anger your only emotion?

3. The implication that you are the target of an attack by the KGB sounds like the classic move by a KGB-type to direct suspicion away from himself. Hiding behind pseudonyms is another.

If you guys can recall, the Aro was developed with the Linn Troika and the Karma. It was found that overtightening the mounting bolts seriously affected the sound. Bad. We also found that there was no "fixed" torque settings as cartridges all vary. FWIW,as everyone seems to have a different idea of what tight means, we recommend that the cartridge should be "nipped up" and should then be listened to. Further tightening will reveal performance changes. It's oh so simple. Trust your ears and NOT what others tell you. Paranoia strikes deep. The mounting bolts supplied are more than up to the job.

MM,

(4) It seems to me you have lots of information, but it conflicts. This is not surprising. Linn & Naim have different design philosophies.

This will lead to different setup advice, and may also mean that the Aro is not designed to take the sort of tightness that Linn recommend.

You know Linn's advice. Send an e-mail to Naim directly asking them for their setup advice (they will have lots of experience with the Troika), and also for any warnings re over-tightening.

Oops, spoke too soon.

Doug,

Thank you for your alightnening answer. I will try to translate it to Hebrew because not all understand English:

1. Linn is wrong. Chapter "Cartridge Align" of
"Linn LP12 Set Up Manual" is deleted. You have to experiement with tihgtness and in any case to not overtight cartridge bolts.

2. Strong Linn supplied bolts are overkill, you don't need SO strong. Naim stuff is more than enough.

3. There is nothing special about Aro design that facilitates change in Linn cartridge mounting procedure. So (1.) and (2.) applies to Ittok and
Ekos arms as well.

I type these words and don't beleive I do it. My fingers are trembling. Now I will press "Post Now"
and certainly immediately will get "invitation"
from Glasgo policy officer(and why it seems to have face of one of the Naim forum members?)
So I will sink to underground as quick as I can...

"Linn is wrong".
No thats not what Doug is saying the aro and the Linn arms are two different concepts. Different designs and materials demand different ideas for set up. Stick to the manufacturers set up advice if you can find it!.
easy!

Thank you Paul. I have full picture now after your message.
Sorry about my a little provocative writings but
it's not easy at all to get any valuable and true information...
