Pscialli, I think the dealer might be the only sure source for a Linn platter. Finding bits and pieces on AudioGon or Ebay is spotty at best for a non-upgradeable component but, not impossible. If youre running a goldmund platter, is the spindle a Linn component with the Cirkus? I had no idea that such a thing was available. It leaves me curious to whether your non-Linn upgrades are helping or hurting or just changing the flavor. If I were you, I would pack up my table, go to Gifted Listener (who I've heard excellent feedback about) and A/B your table against a similar Lp12. I realize that it will be nearly impossible to do a real apples to apples comparison but, it may help you understand if the true Lp12 sound is vastly different than yours and whether you truly dig the groove it makes or if you need to head in a different direction entirely. On the chance that you like what you hear than comes the hard part of sorting out what has to happen with your deck. It sounds as if the rest of your set-up is of a good caliber so I dont recognize a mismatch there. Personally, I would look at upgrades in this order 1.Lingo, 2.Ekos, then 3. Keel and agree whole heartedly with Newmanoc comments as far as value is concerned. The Lp12 on the used marked is a tough act to follow for the dollar. IMHO nothing comes close in total package, musically.
Happy Listening
