What is your recommendation on upgrading a Linn LP

Upgrading a Linn? Don't waste your money. Even a fully upgraded up to day Linn is still terribly colored and not up to any of the competition. Except maybe an AR.

I already own an expensive, "current standards", "neutral", massive, unsuspended turntable fitted with a Graham Phantom MkII which IMO beats, hands down, any of the alternatives mentioned above and I personally would be more than happy to own a 2nd hand Linn LP12 and tweak it. ;^)

Just my opinion....

Well..I already own an epxpensive digital player that beats any of the alternatives suggested above but that means nothing in this discussion..I would rather spend half the money and get a better sounding table IMO than taking a thirty old table and try to tweek it,,been there,done that..Waste of time

I own a very late 80's Linn plinth...that's all that is left of my original table. To that I have added a Cirkus/Kore and a Radikal D power supply, a Tramp 2 base and new springs, etc. The arm is a custom WTA Black arm with VDH internal wiring. I just AB'ed this table against a new Palmer with the Origami arm, the Palmer owner easily heard why the LinnLP12/Radikal D is still one of the top tables today.
The Palmer is now going on the block for sale!!
To those who have NOT heard a current top spec LP12SE, I suggest a listen before one comments on the demise of the LP12!! As to the OP, I would suggest, depending on funds, an upgrade path of your table, one that can be best suggested by your Linn dealer.

Excellent point, Davey. Rumours of the "Death of the LP12" are greatly exaggerated... ;^)
