Direct Drive vs. Idler Drive vs. Belt drive


I'd like to know your thoughts on the strengths and weaknesses of each drive system. I can see that direct drive is more in vogue over the last few years but is it superior to the other drive systems? I've had first-hand experiences with two out of the three drive systems but looking to learn more.

The old and refuted Aristotelian methodology discriminated between
''essential'' and ''accidental'' properties of objects. His physics  is
refuted by Galileo his logic by Frege.
Those who are not familiar with modern methodology still use 
Aristotelian ''essentialist philosophy''. Think about ''essential 
part'' by MC carts being the stylus and its shape. The kinds of
''drive'' by TT's etc.,  etc., etc. 



Addendum. Some examples can illustrate some ''state of
affairs''. Say the question why Russians think that Hegel is
the most important philosopher? Because of his (dialectic)
Logic? Well he wrote an big book (in two parts) with more
than 1000 pages with the title '' The science of logic'' in
which there is no on single sentence relevant for modern
logic. 
 
What has Hegel and Aristoteles to do with our forum?
We have seen Aristoteles  ''essential properties'' but need
to add Hegels ''logical invention'' called ''the unity of the
contradictory''.
According to chakster  the micro ridge stylus is ''essential''
while our eloquent member from Australia was so impressed
with his Sony XL 88 D that he declared the precious  to be the
best ever (in his) collection. He ascribed this ''quality'' to the 
(diamond) cantilever but the case is that this cart has  elliptical
 stylus. Aluminum cantilevers? Are you joking ? Never heard about 
beryllium or ,at least, boron or ruby cantilevers ? But the same
person ''confessed'' that among his darlings belong FR-7 fz as
well Takeda's Miyabi. Both with aluminum cantilevers. 
Such, according to modern logic inconsistent statements, can be
found in nearly each thread. That is the ''connection''. 
 

Dear Tom, How get people  this conviction about 'essential'',
''original'' and other ''properties'' of objects? The most are not
familiar with Greek believes which are ''transfered''   by education
to the next  generations. Think of Greek ''metal analogy'' by 
describing  persons; ''iron strong'', ''honest as gold'', etc. In 
social science  one was looking for the ''original 
meaning of words''. to explain their ''real meaning'' . Your
 examples testify of the  ''opposite meanings'' of ''terms''. Hegel
 was master in the ''opposites''. Each  term has its opposite
 while opposites have  their own opposites.
He constructed an labyrinth of words and was not able to find
the way out. So he ''solved'' the problem by invention of
''unity of opposites'' like the unity of the contradictory. But, alas,
words are not linguistic entities which can be true or false. Those
are statements, sentences or propositions (choose your own).
Kant and Hegel never grasped that they are talking about language
not about reality. That is why they were obsessed  with ''meanings''
thinking that those ''explain reality''. But what kind of things are
meanings? The so called ''theory of meaning'' has lost the battle
with ''Theory of reference'' . Reference , uh, refer to external
objects in the reality. That is the connection with language. 
Japan was so successful because they improved the ''original 
products'' from the West . Why are Americans so obsessed 
with ''original parts''? 
Why so many in our forum think that there are ''essential '' and
other ''not essential parts'' by each composed thing from parts ?
This is because of Aristoteles influence in the Western education.
His ''authority'' ruled for 2000 years in Europe. Some social
scientist  still search for ''essential things''. They are also talking
about the meaning  of terms.





Generating ''new words'' by adding up phoneme. There are
''left hand''- and ''right hand'' methods
The Romans were left with ,say, RES on the left side and addition
on the right side. ''We'' are the right hand 

RES- nulius (property which does no belong to anyone; free)
RES- sacre  ( saint objects)
RES- immobiles (movables)

PROPERTY- movables, real estate .etc.
ELLIPTICAL- ''super''  and other kinds. 
 
A kind of word ''root '' is assumed which can be modify by
adding some phoneme to the right or left side of the ''root word)
But I have no idea how this works in Australia (grin).
Addition, the problem by ''Australian English'':
Australian ENGLISH,
New Zeeland ENGLISH
American ENGLISH
British (?) ENGLISH 
Our forum ENGLISH
Raul's ENGLISH, etc
BTW deed anyone in our forum try to put together LP 12 from
''original parts''? Is any improvement possible without
changing some parts? Are those than worthless because
of the lack of original parts? 
 
Our dear member whom we assumed to be an ''former member'' is
back. Welcome back thuchan!
Lew congratulation with your new compressor. 
 
I like disputes but not with dover (grin). I started an thread
with the title ''irreparable cartridge'' but nobody was interested.
Curious because my explicit reference was to Sony XL series
and ZYX series. The reason is the glued body with no possibility
to enter inside for eventual repair. It is , I think, never mentioned
that among other innovations Sony was the first with  ''potting''
the inside of the body. Axel needed to break the body to get
inside but inside he was confronted with ''glue'' as he put it.
That is some ''glue kind'' of damping material. Now regarding
 the optimistic inclination about retip. Those who thinks this 
possible have never seen  Sony XL 88 D. The diamond and 
consequently the ''joint pipe'' are not round . Besides the diamond
cantilever is not glued in the ''joint pipe'' in usual way. What Axel
was asked to do was straighten the cantilever/stylus combo.
This was, alas, not possible because of mentioned fastening.
That is why he needed to ''break in'' inside. The whole generator 
was somehow ''turned around'' . By straightening the generator
the coils  were broken in this (potting) glue. I lost my Sony 88D
this way while my initial thought was: ''easy job to straighten the
stylus''. 






 
bukanona, Changing the whole ''motor' and adding Namiki
cantilever with glued in stylus is some other ''animal''
than Sony's one peace diamond for both. For 2000 euro
you will keep only Sony's body which I blamed for the impossibility 
to retip or repair. However anybody has right to its own thoughts. 
Dear Lew, You can then see and hear Eckard's more beautuful Sony XL 88D in its integrated  headshell.

Bukanona, I deed not use the expression ''glue'' but referred to
Axel's description of the stuff with which the Body was ''potted''
 in order to dampen resonaces. Even Axel with 40 years of
experience has never seen this before. I have no experience 
with other carts in the XL series but assumed that those are
also ''potted''. All of them have the same ''8 form coil formers''.
So if one can get entrance one can probably buy, say, XL 44
as ''clone'' for the coils of other versions. .I assume that XL 55
has round cantilever and joint pipe so in this ''pipe'' an new cantilever/stylus combo can be glued in .By the most retips
the old cantilever can be removed by some solvent so that
new cantilever can be glued in. 
Dear thuchan, I am 83 old and have difficulty to  walk longer distances than, say, 200 m. You and my other German friends invited
me for the Munchen show many times but being all globetrotters
never thought about my physical limitations. Mea culpa but as
an brave Serbian  warrior I was not willing to confess my own
limitations. Distance is not an border for love and friendship. 
I consider myself still as member of the ''German group''.
bukanona, I mentioned explicit that among other innovations
Sony introduced ''potting''. My (forum) brother Don explained
to me what ''potting'' means. Leto Andreoli whom Dover consider
as artist among cart producers also use this ''potting'' technic 
but by his  Magic Diamond one can see this ''potting material ''
from outside. 

My Gosh I though that propaganda was invented in Germany
(Goebbells) and Sovjet Union (Molotov?).
But my grandad always blamed British for every bad things. 
He looked than in special way at the listener. I was sceptical
because I was able to read ...That is probably the needed
capability for propaganda. 

edgewear, Your accusation than I am Dutch is curious because
I am an (brave) Serbian. But you are right regarding CD invention.
As you should know I am member of analog religion.
edgewear, While I am an (born) brave Serbian I don't believe
that all Dutch people are to blame because Philips is an Dutch
company. What about Linn then? Do you agree with my grandpa?
I posted my latest contribution before I ended my writing. There
is ''Preview'' and ''Post...'' so I obviously pressed ''Post'' instead
of ''Preview''. What I wanted to add is that ''referencial theory of
truth'' won the ''contest''. Scientist are interested in the 'real theory
of truth'' and consider the so called ''propositional attitutudes '' as
not truth funcional. So ''whishing'' ,'' hoping for'' , ''believing that'',
etc . statements don't  satisfy truth criteria. They also defy 
logical analysis in the sense of consistency. 
I see that edgewear, say, like the referential theory but the names
which he uses are referential opaque. With Dutch he means all
Dutch but the quantifier ''all'' is not an name. It is used for universal 
statemens like ''all x are Fx& Gx'' . But if one x does not satisfy
conditions F and G then the whole statement is no truth.
Then the reference to UK is not ''correct'' according to him because
Scotland is not included in UK. It is the only country where Linn
LP12 are made. So the statement Linn is made in UK is not
true? Well ''extension of names'' is difficult ''subject''. Frege's 
definition of numbers was ''extension of notions'' but was 
refuted by Russel because of paradoxes in the theory of sets .
More in particular by ''sets of all sets'' (grin).

''Meaning and truth'''. There was an attempt in the philosophy of
language to establish theory of ''emotive meaning'' of words. One
can use the expression ''notions'' instead of words because the
most have ''notional mental orientation''. We all learned difference
between ''neat'' and ''rude'' or ''impolite'' words. That is how psychology is involved in ''understanding''. All advertising is based
on psychology. The buyers need to be seduced.
What does ''improved version of x'' means? Linn LP used this
''notion'' each time because echt time the price could be increased.
 No need to explain ; one only need to compare prices.
What does ''original'' means? More in particular in USA. Old 
cars cost much more the new provided they have ''original parts''.
I have seen old  Italian cars which are sold for millions dollars .
But is any improvement possible without changing at least some
parts in the construction. I asked the question in this forum:
'' has anyone try to put an LP together from original parts?''
Does ''original'' means something else in this ,uh, context? 
Well in ''our present context'' the notions ''DT'', ''Idler'' and ''belt''
