Turnable database with TimeLine


Here is a database showing various turntables being tested for speed accuracy and speed consistency using the Sutherland TimeLine strobe device. Members are invited to add their own videos showing their turntables.

The real question is are these very, very small speed changes AUDIBLE!

I seriously doubt it!

Tape recorders and cutting equipment does not have perfect speed in the first place.

Many audiophiles like to split hairs with theory that makes no difference in real life. This is just golden ear BS!

8 feet to the wall, that is a tough test.

I understand your skepticism, but would argue that these micro speed changes are indeed audible.
Sure we have tape machine speed instability along with eccentricity problems. That said, speed changes due to stylus drag, which is where this thread has kinda coalesced, are fundamentally different in nature. This because the music itself causes it. This results in a subtle smearing and bending of the notes. A general softening of the soundscape. The effect can be " nice " but it is not what was laid down on the record.
I would like to again offer my Timeline Calculator Excel file for anyone who would like to try it out. You enter the distance to the wall and the laser deviation per revolution and it gives you the circumference of the virtual circle that the laser travels, the speed error of your platter in percent, the RPM your platter is off by, and the actual RPM of your platter. It can also tell you how many Hz a given frequency is off by.

Here's the original thread:

Ketchup, I'll take you up on your offer. How do I get my email to you so that you can PM me? Thanks.
Richardkrebs - the music you inquired about is Cantigas de Santa Maria #77 - sounds like Jordi Savall - he performs in Auckland from time to time during his world tours. Highly recommended.
