[#12] Weiss 202 & Apogee Big Ben external clock    
tested by sound of sound magazine

An Apogee PSX100 was sync’ed to two external clocks, and again, the result was worse than on its own internal clock — although it appears that the Apogee is better at slaving to external signals than some of the other devices we used in our tests.

cryingfreeman,

I ensure Kent know this approach already and even better but it is a rare usage for general audiophile. At day one he informed me the availablility of my Weiss dac202, he did suggested me to use the DCLK out to feed my dCS P8i....I tried and cannot fallback, the sound of dCS improved a lot !!

Dear Kent
If any DAC has WLK I/O, we advice to use the WLK output to sync the source (assume the source can be external sync). In such way, this digital system have 1 master sync and it is the DAC.

If following your approach is better, is it something wrong about AudioTechnique magazine?
If it is a fact that the connection from AudioTechnique magazine can produce better sound, is it something happened about 202?

Pls advise

Maybe master clock is a new area for audiophiles, most people do not understand its function well enough.

Regardless if external clock can improves sound quality, for a digital system, there should always have only 1 master sync.

e.g.1 CD Transport -> DAC (CD Transport is the master sync, DAC is the slave)
e.g.2 Computer soundcard -> DAC (soundcard is the master sync, DAC is the slave)

As you can see in normal operation, the master sync is always at the source.

If you wish to use an external master clock in this system, you should either lock both units, or the source to the external clock (WLK), instead of the DAC.

e.g.1 CD Transport (BNC sync to WLK) -> DAC (BNC sync to WLK) - Both units are working under 1 external clock
or
e.g.1 CD Transport (BNC sync to WLK) -> DAC (Slave to digital input e.g. AES)

If you lock the DAC to external master clock but not the source (e.g. CD Transport)

e.g.1 CD Transport -> DAC (BNC sync to WLK). You have 2 master sync (one is CD transport, one is external master clock) in this system and therefore it will not work properly.

If any DAC has WLK I/O, we advice to use the WLK output to sync the source (assume the source can be external sync). In such way, this digital system have 1 master sync and it is the DAC.

This is also how the Weiss works with CAS (firewire connection).

I also think that Big Ben is just a mid-level clock that is already several yrs old.
Weiss 202 is a new & high-end DAC with premium internal components.
I doubt the Big Ben clock can further improve it.
It's more convining if the clock is a high-end one from Antelope Audio or Grimm Audio.

According to a Weiss 202 review in this month's AudioTechnique magazine (page 214), there is significant improvement when Weiss 202 is fed with clock signal from a Apogee Big Ben.

1. 202 clock = rubbish
2. bigben clock is better than a lot
3. a writer!

anyway, forget 202 la...

dramis hing,

I certainly know his track record!

But I also want to know the true experience & comments from 202 owners & C-hing.

This is quite surprising. Weiss 202 should have a very high quality internal clock.

Also, the reviewer says that reclocking the digital out of his Lindemann DDC 24/96 via the Big Ben gives rise to improvement too (page 283).
