This constant myth that the LP12 goes out of set-up easily just ain't so folks.
I had my LP12 with Valhalla for nearly 20 years with no issues with regards to set-up. The TT does indeed need to be set-up correctly in the first place, BUT once that is done, it will not wonder off set-up anymore than any other TT.
Now that I have the LP12 updated and correctly set-up again, I am certain that the new set-up will last an equally long time.
BTW, Schubert, too bad that you didn't take advantage of the gift that someone gave you...with a good set-up that table would have eaten your AR-XA alive.
