Upgrade my older Linn Sondek or move on?

Couple of great upgrades are available for you with the LP12. Replace the bearing to the current Karousel and replace the arm...look for either a good used Ittok, or if funds allow...a used Ekos or Naim Aro. 

@ghdprentice The OP seems to have a c. $2k budget.

I have a few friends who have Belt Drive TT's, I have shared this info before.

One TT is a Brand that is modern, one TT is a older model from a Brand and modified with OL Parts and the other is a LP12 of similar vintage as your own having undergone some of the available upgrades (note Linn are not the only Company with Upgrades on offer for the TT).

The demo'/comparisons were far from perfect, as a result of using different Tonearms and Cartridges on each TT.

The outcome reported from the attendees was that there was not too much to be discovered, and the Linn was as attractive in use as any other being demo'd.

There might be discovered within the Link some info that inspires you to keep on with the Linn.

@noromance  If I sell the Linn the budget will be $3.5k.
@ghdprentice No local Linn dealer. I would have to do the upgrades myself. Not completely opposed to doing it, however I would like as close to as little set up as possible.

@pindac thank you for the link

@thermionicemission Not to split hairs but I was addressing ghd who is assuming you keep the Linn and therefore have $2k. I’m cognizant of the $3.5 ‐hence my recommendation for the $4k 1200G. A friend has had the Tangerine (modded) LP12 and much prefers the Technics.
