Default LINGO vs. LINGO-II and LINGO-III - where are the differences ??

At starting this thread I look only to the first version of Linn's LINGO.
There are at whole three versions of this synchronus motor control device (MK-II and MK-III resp. Lingo-2 and Lingo-3).
Who knows the exactly differences compared with the first version?
This URLs don't provide the wished informations:
Lingo vs Lingo II
Naim Audio Forums: Lingo I --> Lingo II ?
http://small.linncdn.com/product-cat..._Manual-DE.pdf

Who know more?
Thank you for advices.

I can't go through every step.

1st version, old case, linear psu, discrete components.
Current version, new case, Brilliant smps, smt components.

I doubt the performance has changed one bit.

They had to put it in a fancy new box, to match the other bits.

Blue-box traffo is the v1 and you are missing the latest version inside the new case with smps.

Default spectrum of 1kHz sinewave by two different "LINGO" devices

go to Fig. 1 and Fig. 2 (1990 sample vs. 2003 sample) to this URL:
Linn LP Playing System Measurements | Stereophile.com
BTW - nearly perfect looks Fig. 3 from the Pioneer model PL-L1000
completely paper:

Interesting, the Linn has the narrower peak, but also has secondary peaks at -40db and also a higher overall noise floor. IME the Linn looks and sounds good until you hear what better really sounds like, then you realise how much of the Linn sound comes from the interaction of the suspension stability and the motor drive.

Which effects cause these peaks at a listening test ?
Maybe a more harsh sonic transmission ?
Or more the same effects as with flutter at tapes.

I can't prove it but I think those first peaks at either side come from the suspension being set in motion by the belt drive, they likely equate to a side-to-side wobble.

The peaks at +/- 50hz and 100hz from the fundamental test tone frequency come from the frequency of the mains and are break through into the drive system. This I have tested, you just swap the motor for the same motor with a different size pulley, (ie Linn for Kuzma) the fundamental will be different due to pulley size but those peaks still occur at +/- 50hz and 100hz just the same. They don't sync with the number of poles in the motor or the rpm of the motor so they very probably come from the mains frequency output by the psu.

The effect of these peaks is harder to pin down. I think the 'musical' feel of the Lp12 comes from the narrow shoulders on the steep slope of the graph, it is these that give the LP12 a lot of its delivery, the way it 'gallops' along, its sense of timing.

The +/- mains frequency multiple junk is pretty low level. I wonder if anything can be directly attributed to it.

The 100 Hz peak is the so called twice line vibration this is the main problem with turntable motors .
