Question on Denon DL-103 retipping options and preferences
Justin  you might want to talk to Jeff at audiomod.  I built the 1st or 2nd kit  he had years ago.  He made  head shell weights for the  the arms for  the 103.  Ask him about rock and roll and jazz with the denon 103.  I pretty sure he has used or...

Spindle-To-Pivot Distance
Lewm  the arms are my own.  The ones with the zero offset  are Brazillian  rosewood with a straight  aluminum headshell.  I use a spacer block of aluminum  or wood for now, between the cartridge  and headshell,  so any angle is available including... 
Spindle-To-Pivot Distance
Lewm you brought up the question  that 1st popped  in my head.   Could you move it  10mm  and still have 2 null point.  With the calculator  on vinyl  engine  you should be able  to solve with the variables  he knows.  He could also go to vinyl  a... 
Spindle-To-Pivot Distance

A 60 year old turntable design is still going strong!
One more idea about how a turntable should be designed.   The concept of things getting out of the way is  optimistic .  Everything  has some  effect.  Having not built  a turntable with that  arm bearing plate combo I really  have no opinion  or ...
