30 years on...

Then you need an LP12, CD12 and ATCs (or Quad ESLs). Job done. Problem solved. End of hifi business career...

Hi,

You cannot assume equivalent inertia. Because by the time you have made a solid piece that is equal in resisting torsion and bending it will be considerably heavier. However, it will also have a very different resonance behaviour, which is the result of the high stiffness in a specific dimension.

I find it most interresting that the most advanced and highest performance tonearms usually avoid tubing and often have significant solid sections (examples - Dynavector, Souther Triquarz, Rauna Cantus, Schroeder). Maybe food for thought....?

For strength i expect.
Do you try hard to be this daft, or is it natural to you?

 

Vibration is a form of kinetic energy Paul.

You know I heard an LP12 for the first time at the weekend and thought it was a very nice deck. In fact if I could have done I would have taken it home with me, but the owner liked it to. As a second hand buy it's very very good, I'm still not quite sure what you're arguing about guys? I'm getting this kindofgoingroundinbigbigcirclesfeeling..
Tell you what, why don't you all sum up your arguments in less than say 100 words then everyone can rest assured that they've had the last word and the subject can be put to bed

 

Paul, which turntables other than the LP 12 have you heard under controlled conditions, i.e. in a familiar system?

 

Hi,

I'll take the first word summing up, rather than the last.

And I'll do it in much less than 100 words.

The Vinyl Axiom:

"The less a turntable is like a cutting lathe the less it operate as "cutting lathe in reverse". The less a turntable can be seen as cutting lathe in reverse, the more it must alter the sound of a record played on it."

The first Ammendment: "Alterations to the sound of the record from what was actually mixed, cut and pressed may be percieved as desirable or likable by some but not by others."

The last word: "Any discussions about taste are just like asking if the fatness of the pig is more or less green than the designated hitter rule."

"The more a 'reviewer' (or any fellow audiophile) is impressed with the Linn LP-12 in comparison to any of the finest turntables recommended above, the less credibility (with turntables) he or she deserves." - Arthur Salvatore

 

Maybe you can explain what 'vibration' is, in your world?

 

I believe you write for Stereophile. What do you think of the Stereophile review, Markus? And what about the allegations of corruption?

 

None for a long time. I'm sure there are very many fine turntables out there. But I know that for Thorsten's stated aim an LP12 is good enough, and as it's the subject of this thread...

Paul

 

Markus.....?

 

To and fro motion. I think it's quite a common concept.

Vibration is to energy what a battery is to charge.

I'm intrigued by your vibrations causing amplification, there's probably a patent in there somewhere.

Paul

 

As you are hard of thinking i will try to give you some help.
Why are hollow box like enclosures used behing the vibrating strings of guitars, violins etc..

To and fro motion, that would be a form of kinetic energy then (kinetic meaning movement energy, look it up)

 

Pe<>ke

 

Potential engergy (stored) to Kanetic engery (being used) do thou not remember Physics laddie?

 

What about when the vibrating thing is stationary, as it is each and every 'to and fro'?

Next, Rocket Science!

Paul

 

Yea, sorry Tone. Deleted when i remembered.

Mr Ranson, you are to dim to grasp it, did your school teachers give up aswell?

Heaven forbid you are ever near a rocket, it would get no further than the ground.

 

Before we get into the physics of guitars I think you should explain why you think there's an analogy. If you go back to the knuckle test and rap a guitar and rap an LP12 it should be clear that the latter would make a terrible acoustic guitar body.

Paul

 

Please, Please re-read my posts and stop confusing what i said with what others have said.

James asked a question, whether a hollow plinth is better/worse than solid.
I am not talking about an LP12 in particular, just about hollow vs solid structures.

You obviously either cant grasp some basic principles or you refuse to correctly read my posts in a vain attempt to stick up for the LP12.

Stop quoting out of context and try hard to grasp the basics.

 

The LP12 is the subject of the thread and presumably also an example of a 'hollow structure'. You may not be talking about the LP12 in particular but you are talking about turntables. It's reasonable for me to point at a real example and ask for amplification.

In the end what you seem to be reduced to saying (I'm having to interpret here) is that if a turntable used an acoustic guitar body for a plinth that might be worse than using an electric guitar body . If that's not what you're saying then explain, without mumbo jumbo about energy transference and non-specific 'vibration'.

I really think you need to go back to basics before you start opining on turntable construction. Stick to how they sound to you regardless of the engineering choices made in their construction, that requires no science at all.

Paul

 

Its hard with you isn't it.
Did 'I' say the LP12 had a hollow structure?
Did i not explain that i was answering a question posed by James in a general format?

Your second paragraph is an obvious indicator of your inability to understand where my posts and others differ. Your hung up on this vibration thing aren't you, i may have an old secondary school physics book around, may help you.

I think your last paragraph is talking about yourself, obviously an inability to accept your own mis-understanding of a subject means you blame others.
The last sentence in my previous posts really does apply to you.
