Default which clock to choose

Hi,

Been thinking about a clock upgrade for my cd playe pioneer (pd-s 703).

There's quite a few companies etc supplying clocks, and the lc audio version 3 does look good. I'm looking for a pre built one, so I can fit it quickly. I may decide to build my own power supply. Has anyone experience with the lc audio clock x03, or the superclock II? Also I know there are a couple of guys here with clocks circuits etc (elso and guido), do either of you guys have a pre built version of your clock, and if so how does it compare to the commercially available clocks?

Thanks

Raja

In my experience & opinion, any clock may be better than the standard...but a good-sounding clock-circuit can easily be worse than stock if the crystal is out of tune. And they often are.
Ask Elso (member) for his circuit, and make him implement a little adjustment
to "pull" the crystal frequency to perfect timing.
Then I guess you will have the best...

Hi

Just my 2 cents:

The clock itself should be very low jitter. In my experience there are few good clocks around.

In addition, the power supply should be low noise. Most comercially available clocks fail here, in my experience.

Beside above mentionned, the price to quality ratio should be considered as well, to my opinion some clocks are just too expensive.

all the best

Hola Jesús

Just looked at the site. No clue about the perfomance, they only give phase noise specs, and there is no unambiguous way to recalculate that to jitter specs.

If I had a sample, I could measure........

regards

Default Clock's

Hi Raja,

The Kwak Clock turnout to be the best one for me.
It's cheap it's a DIY one and Elso is a real gentilman!
The Tent Clock is also good, but to bad it's no DIY Clock.
The Tent clock works as good as the Kwak Clock, no doubt about that.

So If you ask me,............... I would go for the cheapest and DIY one (sorry Guido, but if you had a DIY one, than the choice would be between yours and Elso's. The LC XO3 is a copy of the KC-7, more or less. If some one knows more about theLC Clock, let me know.


Best regards,

Audiofanatic
