What is your recommendation on upgrading a Linn LP

In England, they would recommend you see a Linn dealer.  I know Thomas OK is one in the U.S., as he comments on the Linn Forum.  They usually recommend you get a Cirkus bearing(and now, with the Kore[one subchasis], you might do both at the same time.  If you get a general tune-up, the belt, springs, etc. will be looked at.  It's possible that you could, on your own, change the belt, and add the new Trampolin(the bottom baseboard).  If you have to transport your Linn, they recommend the packing that came with the turntable.  I'm not sure if you have the Cirkus or not(see Linn Forum).  In addition, a new felt mat makes an improvement, and one side sounds better than the other.

If the plinth is nice keep it and maybe start with an Ittock LVII tonearm. Maybe some new springs. Linn makes too many upgrades. Diminishing returns do not always makes sense and are seldom worth the costs for what you get out of it. I've rebuild 3 Sondeks. New motors and belts can help too. The rest is pretty much cosmetics. Good luck.

I owned an LP12 with an Ekos arm, and the one thing I learned in owning this table is: Tune up. Have it set up by a reputable Linn dealer and he will be the best to make recommendations of what should be done. If you don't have a dealer locally, contact Rick at audioalternative.com, he will advise you how to pack and ship the table to him. Once he has it he will access the condition and needs to return the table to optimum performance. Then once you have it, you can start deciding if it needs a new arm, power supply, keel, etc. But that is where I would start, the suspension on the LP12 is crucial to performance and it really needs to be done by someone that does it all the time. Just my opinion of course.
