Linn Sondek- Origin Live upgrades anyone?

I can't speak about the Origin Live upgrades but I am now on to my second Sondek after stupidly selling the first one! They sound great in stock form! Mount a good or better arm and cartridge and the LP12 is still a contender - even sans upgrades! For the cost of a tricked-out Linn the newest Technics DD is a better value - and costs less!

Haven't tried those exact ones for Linn, but I have used a couple tone arms, turntable, mat, belt, cartridge enabler and record weight. If the Linn upgrades are anything like those they will be well worth the money. I would suggest try the belt, mat and record weight first. The Gravity One record weight in particular, it is obvious even before using this is something different. Far outperforms all other weights and clamps I have tried, including my favorite DIY from carbon fiber. The belt also is unlike any other I have seen, with a pattern that appears to be some kind of weave and a warning to test stretch too much even though it is perfectly flexible and does stretch and hold a nice tension. 

Buying into Linn is buying into  upgrades forever. Audiophilia nervosa. It never stops. Get off the merry-go-round

I’m no Linn fan, but even so they are fine tables and that is unfair, and off-topic. Please delete. Thanks!

I tried the 'Advanced' speed control box/motor back when I owned an LP-12 (we're going back well over 10 years) and was unimpressed.  The DC motor was decent enough, but the speed drifted like crazy since it was/is an open-loop controller, without any platter/motor feedback to the controller.  DC motors need some type of rigid feedback system (whether at the platter or in the gearhead itself) to provide constant, real-time feedback to the controller - I've never heard an open-loop DC controller for a brushed DC motor that was worth a damn (though Mark Kelly came close).

The Linn 'sound' is in part predicated around a synchronous AC motor (at least up until the Radikal).  It is, IMO, part of what makes the LP-12 an enjoyable (albeit inaccurate) transcriber.  You'd be better off with a used Lingo.
