What is more accurate: magnetic anti-skating, or barrel weight attached a fishline?

To rauliruegas,  Without a doubt, understanding anti-skating is much more complex that I  had imagine.  Almarg mentioned  some of the points you make in his last response.  I often wonder with all these mechanical and geometrical parameters if analog is really worth it.  As you said it is an imperfect medium. 

 I recently had some bad experiences with both used and new LP's. It seems  even  new  LP's come with their share of pop clicks and surface. noise  About a month ago I purchased a brand new, sealed LP from Music Direct of Vivaldi 's "Four Season" featuring Isak Perlman as lead violin.. His performance is robust and simply spectacular  However, sound quality  was  often marred by pops (some almost explosive) clicks, and  consistent surface noise. The vinyl must have been sourced from  Goodwill stores recycling bin.  And this is supposed to be a new LP!!!

.I have read for years above the declining quality of vinyl used for LP pressings.  I have a 35 year old copy of CCR's LP "Pendulum"  which is virtually silent during play despite less plays than some other older LP's I still have in my modest collection.    

 I just purchased from the Discogs internet used record  Mozart's "Six Quartets Dedicated to Haydn" played by Quartetto Italiano on a Philips label ( issue date unknown, possibly early 1960's)  The performance is sublime, a testament to the dedication and brilliance of  the four musicians.  The sound quality is also extraordinary with a "your are there presence "  However, the vinyl has its share of flaws despite the seller's description of being "almost mint"  The  booklets that accompanies the 3 LP set are beginning to yellow which may be a clue to its age.  So far, I have only played the first LP.  Early out on side two, there is a distinctive hollow echo distorted sound which I know from experience indicates badly worn grooves from either a cheap cartridge or two many plays.  Nevertheless, it is fine recording and a keeper.   Thanks for the comment.

Dear chakster, I prefer the Lustre 801. Excelent tonearm but with

mediocre lift construction. And, as Raul already recommended, the

counterweight(s) should be used in the usual way avoiding magnetic

VTF adjustment. This way the counterweight(s) can be get nearer to

the pivot.

Ralph, I am saying that when the cantilever/stylus is tangent to the groove, the friction force generated by the stylus to groove resistance has a vector directed tangent to the groove, too.  But because the headshell is offset with respect to a straight line drawn from the cantilever to the pivot, there will still be a skating force due entirely to the headshell offset angle.  Interestingly, if you use an "underhung" tonearm (no off color pun intended) with zero headshell offset, then there can be only one null point on the surface of the LP with respect to tracking angle error, but at that one null point, skating force will also be zero, because the forces will line up with the pivot.

• Hold your left arm out in front of you (horizontally) with your palm facing toward the right.
• Bend your wrist so your fingers point further to the right, so it resembles the headshell/cartridge offset.
• Have someone tug on your fingertip in a direction parallel to your bent hand.
