Speed accuracy- how accurate is accurate?


Certainly, running at 33.333333333333 . . .  with a stylus in the groove is ideal. Running an iPhone app I just discovered (RPM), I'm running about 33.55 or 33.56. Table is an LP12 with an 18 year old Lingo. Everything sounds OK- is it ok?

Hugely important - hard to achieve 🎶 once you’ve heard it - hard to go back 

Good Listening

Speed accuracy has got to be very important and for me the best tool is the Sutherland Timeline.
Turntable speed accuracy need only be more accurate than the speed accuracy of the record mastering tape deck and cutting machine!

More turntable accuracy then that does not matter in listening playback sound quality!
