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.

Richard, thanks for this GOLDMUND info. I once owned the Studio way back. And I wondered why there wasn´t pitch control for that expensive deck. This explains it quite well, pitch control wasn´t needed at all. The music that is playing defines the speed stability. A very intelligent system, very sophisticated anyway. It would be interesting to see complicated music been played with the Studio and TimeLine test. Firstly, the flimsy suspension must be tamed/eliminated to make a proper test though. And finally, does the music really sound right ?
Tony, words of wisdom. I have always thought that it´s a miracle that the vinyl groove and the magnetic tape are the recorded music itself. The triumphant victory of post war technology indeed. The modern digital tries to make playback perfect but it´s just an illusion, it still has a very long road ahead to perfection... Meanwhile we can enjoy the music and forget the modern digital technology.
But we can always try to make the analog playback even better and that´s the fun of it ! Here in AudiogoN universe many great minds are searching for the boundaries of the Analog but I wonder if there is anyone who has found them ?
Btw, my very heavy yet very humble TT usually maintains constant speed but sometimes doesn´t... probably due to fluctuations of mains AC. So it won´t pass the TimeLine test. That doesn´t worry me though as I have a very enjoyable system.
Halcro, It would be very interesting to see a TimeLine test video of a very eccentric record´s play with 3 tonearms in action.
Tony, This is an example of playing a very eccentric record:

You see the saddle swaying to and fro smoothly due to eccentricity. If you look closely enough (sorry my stone-aged video quality, well I´m not into videos really lol) you may notice the stylus stays perfectly stationary relative to the cartridge body. So the "wow" is practically caused only by the eccentricity of the record. The music sounds still very enjoyable. In this case the Salvation direct rim motor implementation works very nicely. If we have very sophisticated analog techniques, records can sound very nice despite of platter or/and record eccentricities... and slight warps.
Halcro has just proved empirically the superiority of his Victors. His videos with 3 TAs in action at the same/different time is the most beautiful I´ve seen in hi-fi forums so far. Poetry in high fidelity turntables, and that´s pretty extraordinary. Let´s hope he will get soon fixed his good old TT101.
The speed constancy is the most important feature in TTs to produce music.
I changed from belt drive to the Salvation direct rim drive and the difference was like night and day. Mine maintains the speed stability for most of the time but does not pass the TimeLine test though, probably due to mains voltage fluctuations but that´s another thing.
The L07D is a fantastic vintage DD TT, as many here have posted, like the latest review by Dave the Messenger who praises his L07D over his heavily modded TNT.

Back to square one. We want more videos ! There are plenty of other threads for drive method/TT design discussions.
Halcro, It would really be interesting to see how long my TT maintains the correct speed. Unfortunately I don´t have the devices mentioned available and am not planning to purchase them in near future. Furthermore, I´m not running the Salvation motor in way the Salvation decks do, mine is merely an implementation to a different TT. The motor works more precisely with uber large platters like the Salvation.
And I quite often have issues on mains voltage stability in this remote frontier.
My video wouldn´t do justice to Vic´s magnificent TT.
I would like to see the original Salvation TT in action instead.
