upgrade advice from a Linn LP12


I have an original LP12 with Ittok IV arm and Benz Micro SMS Glider cartridge, in great shape. If I was to go out on the used market and buy a new table, how much would I need to spend in order to get improvement? What is my starting point in cost? I am trying to decide if I want to go down that path.Thanks.

Not much found so far when I checked VinylEngine to see what members there have gone onto.

Here are some links I've found regarding the Linn LP12. If you have already seen these links my apologies for the duplicate info.

Best of luck with the search.
I made the move from my LP-12 Ekos, cirkus to Avid Volvere / SME a number of years ago and never looked back (since then added Sequel upgrade). I feel the Avid has all the postive LP-12 qualities plus much better frequency extension, clarity and pitch stability. Addtionally set-up is a breeze and no longer need to depend on somone else especially with the SME. 4-5 K range used depending on arm
Jim, If you wish to switch from 33 to 45 rpm easily, any of the Lingo power supplies will allow you to do that. I replaced my Valhalla with a Radikal power supply and motor, which while more costly than a Lingo, was a MAJOR step up in SQ.

There are a number of more costly and complex tables on the market today, BUT I still believe a well set up and current spec LP12 will gave any of them a true run for their money....and leave most of them in the dust.
Jimbones, I had an LP12 for a few years and loved the sound quality. I sold it for other reasons and bought a Rega Rp10. Although I know it is a totally different table it has been a good lateral move. If the situation for the LP12 would have been different, I would have bought into more Linn upgrades. My table had the Linto,Cirkus bearing, EKOS arm, Cardas tone arm cables, Trampoline and was set up by the best LP12 man in the industry, Rick at Audio Alternative in Fort Collins,Colo..
That would have been step forward rather than sideways, but I was forced to get away from the suspended table and other reasons. But I looked at the VPI Classic 3 that had the same cartridge, and as nice as that table is the pacing and timbre were to big of a departure from what my ears were tuned to. My point is that the LP12 has a "certain" sound that is hard to find in other tables. I found the Rega to be the closest for my budget. I have heard the. AMG table and loved it, but at 18k, was too big a jump for me.
But I guess my point is, if you are looking to improve your LP playing, and you have been happy with the LP12, consider upgrading it. An EKOS arm, the Lingo power supply, Tiger Paw Khan top plate, etc. But if the 33/45 switching is a motive, as mentioned above the Lingo is a solution. Give Rick, a call he can advise you and help you, I know he gets LP12's from around the country and upgrades and tunes them to the best performance level the table is capable of. He will even send you packing if you need.
