Is it worth buying a ten year old second-hand word clock?

[renan33]

Hello,

I recently tested a low cost gpsdo master clock powered by a JS2 uptone on my DCS Network bridge and I was very surprised by the improvement in sound.
I'm not currently considering a Mutec ref10 or 120 or a Cybershaft 21A because of the price.
You can also find second hand clocks (Esoteric or others)
Is there a deterioration of the clock signal in time?
Is it reasonable to buy a 10-year-old clock or should it be recalibrated?
Thank you for your help.

There is a local 2007 Esoteric D-03 DAC for $3900 .Im also trying to find a modern DAC which will do a better job with the Esoteric P-03 .

See how it sounds.

Phase noise of an OCXO should not change , so if it is a low phase noise OCXO, it will still be a good low phase noise OCXO.

Accuracy will most likely drift, it could be even the external adjusting resistors or adjustment potentiometer which have drifted as well, this could even happen to a much newer clock unit.

If so, you wil unlikly even hear the difference or if it bothers you, you will need to recalibrate any clock unit at regular interval, much like tuning a piano every few months.

For reference clocks, 10M is fed to a DDS chip as a reference and there is a tolerance or it will have problems possibly getting a lock orlock very slowly.

If it was a word clock frequencylike what DCS, MSB uses is a whole different story, at 44.1, 88.2 and 96khz for example, a small deviation in accuracy (i.e this is not phase noise) will cause a shift in the speed much much more critically, much like a turntable running slightly faster (e.g 44.2Khz) or slower ( 44Khz)

So you should be good.
