Upsamplers, DACs, jitter, shakes and analogue withdrawals, this is it.

The jitter problem happens at the beginning of every track.

I tried your method a few months ago, using random access mode, and I also tried using track access with program mode, getting the tracks to be played back starting from the last track to the first. I was hopping that both these methods will make the sled motor travel up and down to lubricate the gears so as to eliminate this problem. However, while lubicated gears does indeed reduce the problem somewhat, it does not eliminate the problem at all.

I have mentioned that in order to sound it's best, the disc has to be played in its entirety once, which has an effect of smoothing the movement of the sled motor. The findings by Todd seems to confirm this. The track-repeat procedure still continue to be required to eliminate this problem. That's because the jitter problem is generated at the start of every track. Only by repeating the track being played 10 - 20 secs after play commenced, can this jitter problem be eliminated.

It is important to remember this, the track-repeat procedure is effective only if the SKIP BACKWARD key is used to repeat the track. Using the numerical key to repeat the track does not have any effect. This indicate that it is a operating software or TOC reading problem in conjunction with the mechanical flaws.

Lastly, this is a technical issue that if resolved can only lead to better sound reproduction for all of us. Anyone who can contribute constructively is welcome to this discussion.
