You guys might want to try an app called Turntabulator. It does give the correct baseline speed of 33.33%. And has a 0.1% resolution for wow n flutter.

Both my TT’s come out as 33.33% exact. (Within the 0.1% resolution).

Use the “exact” mode on the settings menu.

I would worry if a TT does show a variation of 0.1% or more. In my case it shows 0.0% slow or “exact”.

Cheers
In my experience 0.1% is audible, more for sure is.

I tried it. Reads 33.33 exactly unless I mess with pitch or something.

I played around some more with RPM Pro. I did a manual recalibrate on it and calculated the “fudge factor” value to get it to read 33.33 accurately (it’s like 0.989 or something like that). So it can be forced to display the correct speed. It’s a mystery to me why it would need special calibration for something so basic.

However RPM Pro’s wow & flutter number still varies between 0.16% and 0.25%, depending on where and how I place the phone on the platter. I don’t trust that number at all.

Hmm... I bought the Turntabulator app for iOS... It only measures RPM... I cannot see anything for measuring wow and flutter on the app unless I am missing something.

Turntabulator doesn't claim to measure wow & flutter.

Turntabulator claims quick accuracy to 0.1 RPM, or 0.01 RPM over several minutes. It says nothing about percentage, or wow & flutter.

Sorry for the confusion. The app seems to have a 0.1% resolution on speed variation. Definitely not the same as wow n flutter.

Sorry to be nit picking but Turntabulator’s description does not say its accuracy is 0.1%. It says its accuracy is within 0.1 RPM in quick mode or 0.01 RPM over several minutes.

If it was 0.1%, that would be 0.033 RPM if I’ve placed the decimal point correctly. Or if its accuracy was 0.01% over several minutes, that would be 0.0033 RPM. Those are not the specs it claims.

So I got a second PLX 1000 for my secondary system, had to adjust the top tonearm bearing, and the azimuth on the SME socket. Definitely there’s room for improvement on the factory settings for the tonearm. Pioneer should take note!

Waiting for my first PLX1000 to be out of warranty to do the following:

1) external power supply. (to completely eliminate hum on MC cartridges)
2) laser cut Delrin or Ebony arm board for a Jelco 9” arm.

If someone has already done these mods, please share.

Cheers,
Luis

@jon96789 You have to be the person who recently posted a less than stellar review on Amazon that mentioned the sustained piano note issue as well as criticizing Hanpin turntables in general.

Pioneer’s wow and flutter spec says:

<0.01% (Measured by obtaining signal from built-in frequency generator of motor assembly.)

Parse that spec carefully. They seem to be referring to the stability of the frequency generator (oscillator) in the motor assembly. They are not claiming the absolute stability of the speed of the platter is <0.01%.
Actually that's the way Technics determined the SL-1200 spec back in the day (I'm not sure about the new ones).

Actually that's one of three ways Technics specified wow & flutter - Refer to the 5th post down on Page 16 of this thread. Pioneer publishes only that one spec.

Going on 5 years since I purchased the 1000.
I'ts still going strong and sounding great!
I wish I could say the same for the 3 pair of speakers I've rotated since then.....
The JBL 4312 SE's have lasted a year. This may be the end.
