George,

As I read it it compares jitter on a Mac mini WiFI out @ 16b as 268ps p-p and a pc soundcard with toslink out @16b as 313ps p-p.
These are all measured at the analogue out of the Transporter.

I seems from my limited reading that a good DAC can process jitter levels even at nanosecond levels.
So does jitter realy matter if you can reclock?

A previous Stereophile review (May 2005) gave Airport Express jitter @ 258ps p-p.

Using a MacMini directly into a good DAC was popular and as good as a top transport.

A DAC is equivalent to a Pre, the more you spend the more coherent a signal can be retrieved.

So why the issue with jitter, as long as its moderate in the digital domain the good DAC retimes it.
