Question Musical Fidelity A3 CD Player Clock Frequency?

Hey,

Does anyone know the clock frequency of the musical fidelity A3 cd player? If someone has the service manual for this model, please contact me. I'd like to know because I'm thinking of a clock upgrade.

Thanks,

So if i'm buying a tent labs clock, which one should i get? The 16.9344 mhz version? This is going into the reclocking stage in an external dac. I just want the tent labs clock to be synchronous with the one inside the cd player so I won't be dropping bits.

Thanks,

Then it has to be the same one.....not just the same frequency.

Yeah, yeah......I know.....guys claim to do it the wrong way all the time.

So you're saying that I'm going to be worse off in terms of jitter if I do not use the same clock that is in my player?

No.

But they are going to be syncronised. You will drop bits.

There are ways to feed that clock to both places.........................

Hi,

If there is a way to feed the tent labs xo-dac clock to both places, would this be a good way? (without having to buy a second clock for the cd player)

Thanks

If the CS8420 is functioning as an ASRC, I wouldn't have thought that there would be much point syncing the mechanicals to an external dac.

So even if I put in a tent clock inside the cd player, the advantages will be negated due to the CS8420's async clock?

Yes, as the output side the ASRC is effectively a new clock domain but it may well have a separate SPDIF Tx that runs off the 16.9Mhz clock.
