LP12- Power Supply- Need education


I have read a lot about different options to upgrade the analogue power supply.
A phono stage need to amplify micro signal would require very good power supply to ensure there is minimal noise interfere with the signal.
I read about Lingo and other power supply articles, however they never mentioned about the science behind it.
How could a power supply powering a motor will introduce noise to the cartridge especially belt drive?
How do you measure the noise when playing a record?
Or would  the power supply provide a more stable rotational speed, my speed measurement on the turntable shows very consistence rpm once it is playing?
I really do not understand why a Lingo power supply cost so much but cannot provide an improvement with a measurable results.
Could someone educate me.

Like someone posted above, if you have a chance to hear the various power supplies that Linn has available for their LP12, I am fairly sure you will easily hear the difference each makes. The top of the line Radikal D is not just a power supply upgrade, it is also a whole new motor that runs DC. The Radikal D power supply is the most precise power supply option in the Linn line. As such, the rotational accuracy and ability to keep speed regardless of drag from the cartridge is unsurpassed. The DC motor also is extremely quiet and is controlled with accuracy from the power supply. Having advanced from a Valhalla power supply ...which in itself does a better job than the Majik power supply, or the old Nirvana power supply, I can tell you there are huge gains to be had from going up the chain. Now, as usual there will be naysayers on this thread, typically from folks who haven’t heard a current Linn Klimax, or who used to own a Linn...twenty plus years ago! Today’s new LP12 is absolutely NOTHING like what these posters state...and the ONLY way you can determine this, is to listen to a top end LP12 yourself, preferably one that has been set up by a pro dealer, and not one that your local car mechanic just cobbled together.

There is, as usual, a ton of misinformation and pure 'BS' being foisted by those who really have absolutely no clue about the sound of a well set up Linn LP12. 
I love this from mijostyn...'listen to a Linn platter, you will be able to pick up radio stations'..ridiculous!
@mijostyn  You say you lived with an LP12 for 10 years...when was that?...thirty years ago!! 
Funny thing, I used to own a SOTA Sapphire, liked it for the time, but sold it and replaced it with a VPI 19, which killed it...then i sold the VPI when i heard what a well set up LP12 could do. This was many years ago, since then I have basically taken that LP12 and updated it to current Klimax status. Only thing left of the original LP12 is the top plate. To say that my old SOTA Sapphire could even come close to competing with my current Linn is a total joke. I will say to you...IF you want to hear how crappy your old SOTA Sapphire sounds, listen to a new LP12 Klimax. LMAO.

@msnpassion. The LP12 Klimax...in its full guise consists of the Radikal Klimax motor controller, a Urika 2 phono stage...which is mounted on the Trampolin 2 base, the Keel sub-chassis and the latest corner reenforced plinth, the Cirkus bearing,the Linn Ekos Se tonearm and lastly the Kandid cartridge.
i personally don’t use a Urika phono stage, or the Ekos Se, Kandid or Klimax cased Radikal. Nonetheless, I think that all of the updates from the stock LP12 from years back transform the table into a far more accurate and resolving platform.
The Radikal and the more rigid subchassis, DC motor, and the more precise Cirkus bearing brought very very significant changes to what was an already good table....but not one that in the past could really compete with the best today. Personally, I believe that these later mods have brought the table competitive again.
Now, let’s hear it from the naysayers who heard a poorly set up LP12 decades ago...or owned one of the basic models and never got it set up right.
You say it feels flimsy??— not sure what you are talking about, or your frame of reference. Flimsy certainly isn’t one of the things that I would describe the LP12 as....robust yes,..flimsy, nah.
@mijostyn,    Since you just posted that the last time you owned an LP12 was in 1980...I think that tells us all we need to know. 
“There is no way to set up a LP12 correctly”...i’m sure back in 1980 that was your experience. LMAO.


”I have not played with a recent one”....but that doesn’t stop you from bringing us your two cents worth...right!
Quit being a troll and go to another thread.
Ivor T used to believe that AC motors were the only way to go, that changed with the introduction of the Radikal...and its DC motor. ( Linn was never supposed to be interested in digital either...that also seems to have changed over the years.) 
Nonetheless, owning both the Radikal D with its DC motor and prior, the Lingo and Valhalla platforms with their AC motors, I can say that the Radikal D is a MAJOR step up in SQ over those speed controllers/motors. 
@phoenixengr   I believe in the Linn Radikal upgrade the motor is a brushed DC design.
@phoenixengr That is also correct. There is an optical reader that mounts under the platter and reads a mark on the platter every revolution.
