Hello

for some time i have bought one Cronos/Hermes/Amanero combo with 24/22 Mhz clocks
for my COD DAC.

Now i have changed to a Buffallo II DAC. It is better to change the clocks to 45/49 Mhz ?
And what do you prefer wich clock is(or sounds) better. The onboard Crystek 950 from Buffallo or
the Crystek 957 from the Cronus ?

Thanks from germany,
Udo...

It just depends on the sample rates you wish to play. :)

Hello Russ,

thanks for your reply.
The DAC plays fine with the 24/22 Clocks(jumper on 1:1on the cronus and async modus). And there is no more advantage when switching to 45/49 clocks except the possibility to play music with more than 192khz ?

When going to sync buffalo with the cronus, what changes i have to made and on which pad are the clock signal soldered on the buffalo II ?

Thanks Udo

No there is no advantage - in fact if anything the lower freq clocks have better phase noise performance. :)

I would not really recommend sync mode on the B-II

Hello

I also would like to know that. At the moment I'm assembling a Amanero Hermes Cronus Combo for my Dual Mono Buffalo 2.

Kind Regards

Phil

This is mainly due to firmware. The B-II firmware may startup and configure the DAC before the Cronus is fully powered and sending MCK, since it is expecting the onboard XO to be operational.

If you use an external controller, you can adapt some of the Russ posted on github to force the chip to reset when the external MCK comes online.
