Eminent technology et2 on Linn Lp12

@testpilot  Your point about a number of arms working well with the Linn isn't actually correct. Unfortunately the opposite is more accurate..there are few arms that work well with the Linn! The Linn suspension requires an arm that is not only light weight, but also has the wiring to it in such a fashion as that it cannot impact the suspension. Many a great arm won't actually work on the Linn..
The OP happened to ask about an arm ( the ET2) that can work on the table, although I think there are better alternatives available today. 
As a 'Linnie', it is my biggest complaint to Linn, that the actual arms that are supplied and available that work with the table...are in fact far less able than the table itself!
IMHO, the basic platform deserves a much better option than the Ekos SE-1, as an example.

The Naim Aro arm (unfortunately out-of-production) is a favorite with Linn Sondek owners.

The reason I am considering the ET-2 is #1. It is available for a fair price. 2# My initial research led me to beleive that is is a wonderful arm and comparable to the best. #3. I  like the fact that it is inusual.

My tech and I will be mounting it.  I am confident he is very capable of doing the job correctly. Do I absoulutely have to have this arm? No. Set up correctly I am hoping this will be a reference table combo that I can hang out with for a long time. 

Thanks to all of you for your wealth of knowledge. It will definite help when the installation process begins. I will be forwarding the info on to my tech. 

@bdp24 ,

I lived with the Et 2.5 om my VPI HW-19 MkIV highly modded for years and found the highly resonant base to be a mountain too high to climb.

pkvintage, the ET2 is a fabulous arm.  I have owned it for well over twenty years and have done a great deal of tweaking and experimenting with it.  I cannot stress enough what an invaluable resource Chris (ct0517) and his thread are for setup/maintenance  info both inside and outside the box.  I strongly encourage you to take any of his suggestions very seriously.  The logic in his approach to this arm is matched only by his ability to choose his battles and to stay cool under fire 😊.  Good luck.
