the Weiss DAC202 offers the best rejection of datastream jitter I have encountered.
Here is an experiment that will show just how well it rejects jitter:
Change the digital source or the cable or both. If the sound quality changes, then it will benefit from a reclocker and a better digital cable. The reclocker will make a bigger difference however. The DAC that is totally immune to incoming jitter is a rare item, no matter what is advertised.
In synchronous S/PDIF , even when source and the DAC clocks are different DAC adjusts its clock to follow average rate of the source. This is usually done with PLL, that often introduces its own jitter. In properly executed asynchronous USB clocks are completely independent.
Certainly true, although good S/PDIF receiver chips add extremely low amounts of jitter. I can compare a direct I2S feed and a S/PDIF feed from the same device and the difference between the two is barely audible and only on certain tracks, at least with my DAC.
Interesting read. Thanks shadorne.
In light of that, I may just replace my firewire cable for a better one. A Diamond or similar. Will look at the used market first.
If the Weiss rejects all jitter, then why would you waste your money on an expensive Firewire cable? Jitter is the only thing you are trying to minimize, nothing else. The reason is that it doesn’t reject all jitter.
Like I said, jitter always matters and the best way to minimize it is a good reclocker that will give you 20psec of jitter like the Synchro-Mesh and secondarily a good cable like my Reference BNC. You can try other reclockers until the cows come home. None of them will beat the Synchro-Mesh:

I’m not trying to make a lot of money here. The SM sells for $599. I don’t need a sale here. I’m just trying to help you optimize your system and give you good advice.
