Is a Linn Sondek LP12/Lingo/Ekos with a Cirkus update, the last turntable I’ll ever buy?

@coachpoconnor  Good to hear that you acquired a nice Linn LP12.
As to upgrades, the next upgrade for your table would be the bearing, going from the Cirkus to the new Karousel. The bearing is probably the most important part of the TT.

You should head over to the Linn Club on the HiFIWigWam forum, which is a UK centric audiophile forum. Linn closed down their own active forum so most folks are over there now. This is the best place to learn and share all things Linn, including the LP12.

I can tell you that the Denon 103 sounds fantastic on the 1200G.  shockingly good.  you have a good plan there. 

I have been away from this party but it seems to me that if you use the OEM tonearm on the 1200G to run a 103, you would have to find some way to add mass, like a hefty aftermarket headshell, if you hope to get the most out of the cartridge.  I've been using an 18g Ortofon LH9000 headshell with my Koetsu Urushi with excellent results, for one example. But maybe you'd want something even heavier.

Hi, @coachpoconnor 

I really like the Tiger-Paw Audio Tranquility. It is still available. For about 1/3 the cost of a Karousel the TPT does make the Linn sound more articulate and “fresher.” The TPT takes only an hour or two to set up. ( Most of the time is spent with a stopwatch observing the platter spin down. ) It doesn’t require suspension adjustment. I think the Karousel is where you want to end up. However, the TPT gives you a nice SQ improvement if you’re not quite ready to spring for the Karousel.  ( Linn pun? ) Something to consider.

I installed a pair of Dereneville Magic Headsell Mats. ( $125 ) I observed a 3 dB lowering of background noise after installing these little mats. I also use the Dereneville platter mat. ( $225 ) Just one of many good mats out there.

On the VPI Forum search for “more on electrical tape.” People report improved low level detail. The originator of the modification can hear a difference on a Linn through the stock felt mat. ( FREE ) 

I also rewired my arm with Cardas Clear wire direct to my preamp, eliminating a few connections and some very old wire. 

I consider the above to be successful upgrades, some or all of which might not be of interest. And I’m saving up for a Karousel.

Good Luck and Have Fun
