Adding a Kingwa clock to a Pioneer PD S-505

Here is the second part of how to improve the quality of an old CD player, the Pioneer PD S-505. You can find the first part here. In this section, I’m going to show you how to install a better, more stable clock circuit into your 505 to lower the jitter. This particular clock comes from Kingwa, that has a series of crystal oscillators for improving DVD players, CD players, and DACs. The price is reasonable. I’ve installed them in three different units and had zero problems, so the quality seems reasonable.

Ok, so why install a new clock? Isn’t there one in there already? Yes, your right. But by using better parts like crystals with lower ppm and also design a very clean power supply to feed the clock, you can make your CD-player sound much better. And the reason is lower jitter.

But what is jitter? There is plenty of excellent places to go read up on it. Here’s some.
