RE: OK

maybe I misread my single source of info. I am happy to concede every point to you.

as far as the match-up between the TD125 and the JVC TT-81, it seems a bit lop-sided to me.

Example; when the first SP10 (non PLL) was introduced, it only managed to compare with a TD125, not defeat it.

The TT-81 is, I presume, far more advanced than was that initial DD offering by Technics. The TT-81
From The Vinyl Engine, (link below)

Specifications
Motor: DC servomotor
Drive system: direct drive
Speeds: 33 and 45rpm
Speed detection: integrated frequency generator
Servo system: quartz locked positive and negative servo control
Starting time: within 1 second
Wow and flutter: 0.025% WRMS
Rumble: 63dB
Speed deviation: within 0.002%
Platter: 310mm diecast aluminium
Dimensions: 150 x 358 x 358mm
Weight: 8kg

----------------
The TD125 design was originally concerned about reducing rumble. And its published performance spec suggests -68 (weighted) db for rumble. That is a tad quieter than the JVC

When it comes to wow/flutter, we expect the JVC to win and it does with a published .025%. Compared to the Thorens at .04%.

Speed deviation for the Thorens isn't published anywhere handy. I'll just presume that the newer technology wins.


------------

What may have been a closer contested comparison would have been between your TT-81 and a TD126 MKIII. The MKIII has a DC Servo with feedback loop type of control system and does report much lower WoW/Flutter levels than did any of its predecessors within the Thorens line-up.

As I recall, the belt driven TD126 mkIII still came out 2nd place when compared to any high quality direct driven table from that era.

Specs aside.
I have three distinctly different drive types represented within my current turntables-ready-to-play line up. An idler drive. A belt drive with AC synchronous motor, and the SP10 mkII with its DC servo PLL drive system. Each type presents positive attributes that certainly manage to put forth an enjoyable listening experience. But each presents a very different character from the other. Except that the SP10 mkII seems to present little character at all. It seems, by comparison, to be damned near perfect in every aspect of its operation. It plays music impeccably. Perfect pitch on sustained piano. Always correct with rhythms. It certainly has excellent drive and when the music has energy, it presents it. Clearly a winner. Accuracy seems to be its defining character. For now, it is my reference.

I would be more interested in a comparison between a TT-81 and the SP10 mkII. Which one wins in that comparison?
