Moerch UP-4 v. Audio Technica AT1100 tone arms

Thanks very much for sharing your thoughts!  

I had a chance to get a UP-4 as an upgrade from the AT1100, and suddenly it occurred to me that the AT1100 may outperform the UP-4 (I had a UP-4 decades ago and remember little about it).     

I have two AT1100 wands.  One shall be kept stock for use with a cartridge requiring low arm mass.  The other wand I plan to use with a mono MC that likely requires higher than stock mass. 

Do you see any problem adding mass to one of the AT1100 wands?  I am not sure what is considered the best method to add mass.  I presume clay of some type is good to damp resonance.  Your thoughts welcome!

Best,

Dear @spkrplus: AT 1100is way superior to the UP-4 ( I owned the 1100 and Moerch too. ) that's a copy of the japanese Highphonic tonearm.

First disadvantage of the UP4 is that's an unipivot design totally non-stable no matter what, second the 1100 is extremely very well damped design that's a main target with any tonearm, in the 100 we can choose the kind of skating force depending of the stylus shape. There are several advantages of the vintage 1100 even the internal wire is pure silver, the 1100 is a true lesson in  tonearm design.

Regards and enjoy the MUSIC NOT DISTORTIONS,
