Cadiver,  
 
end of the day, its still a Garrard 301, even though the platter look stainless steel machined and probably upgraded bearing. My friend once listen to my own Garrard and he could not tell the difference between mine and his own Shindo version. I have to admit, at the time I made the plinth based on the Shindo.

回覆 (1979): Decca ffss vs SPU G
朋友,  
 
You are right the offset is completely different and yes you need to adjust the pivot position. I checked the schick column which is 19.05mm the SME is 20.58mm so the SME collar would be a bit loose. Not sure abiut the ffyx version. Best to ask

The latest talk on pricing seems to be US$8,900 as an introdution price, which will be raised to around US$13,000 after a year!

>If vinyl is that inaccurate might as well throw away all the analog hardware and software and listen to digital only. BUT wait, how come my ears tell me otherwise, it has more information and is more musical, must be something wrong with my ears, and my eyes too. <  
_______________________________________________________  
 
Inaccurate doesn’t mean it has to sound bad! Digital, as Bobui mentioned, also has jitter, so it is not that accurate after all!  
 
Of course, if you can get everything right, analogue can sound even better. Just that some of the problems simply can’t be solved by the end users, such as the mounting error of the stylus.  
 
Actually, even the cartridge manufacturers may not have much control over this issue, as nearly all (if not all) of them need to buy stylus/cantilever assemblies from outside source. If I understand correctly, there are only 2-3 companies in the world than can supply stylus/cantilever assemblies.

' Well, if you realize the typical amount of mounting error of the stylus on the cantilever, not to mention the asymmetrical cut of the diamond, you may very well give up on this ultra-accurate alignment practice. Basically, if you align the cantilever, the stylus is off, and when you aligned the stylus, the cantilever is canted! '

King,  
 
I say "good for all applications" because it makes little difference whether the null points should be 66 instead of 62, 120.9 instead of 120 mm etc.  
 
Overhang can be accommodated if the arm pillar hole is a little oversized and offset angle can also be changed by twisting the cartridge correspondingly.

Regardless of what pivot arm you use, the 2 null points at 66 & 120.9 mm should be good for ALL applications.

Ivanto,  
 
Regardless of what pivot arm you use, the 2 null points at 66 & 120.9 mm should be good for ALL applications. If you cannot have the second point, i.e. 120.9 mm exactly aligned, it won't make much difference though.

幾天前和Daiwok傾用他的內窺鏡技術來攪,這是否有的水平  
--------  
that is no use. what one wants is to be able to measure the tip lateral movement relative to the cartridge as the arms move along the disc. this is a bit tricky since the tip is relatively small.
