"Mini" to Optical for Airport Express

Also, what is Is2 and why is it superior?

Streetdaddy - the Toslink input is available, I have not updated the website yet. I'm currently evacuated to a friends house by a 10K acre forest fire in Oregon. The Pace-Car also now has S/PDIF output as well for standard DAC's.

Streetdaddy - I2S is the native interface for most D/A chips. Whenh you send a S/PDIF signal to a DAC, it must be converted first to I2S before going to the D/A chip. The fact that this conversion is not necessary reduces jitter.

Thanks Steve once again for being so generous with knowledge. I'm very interested in the Pace-Car as my wife and I are mostly enjoying music at home using iTunes. We have an iMac G-5 streaming to an AE, to the Toslink input of my Marantz prepro. A curious glitch we've had with the AE is we get annoying noise bursts between tracks on occasion. I've unfruitfully petitioned Audiogoners for answers. But you're the man I believe knows what the fudge is going on. Would the Pace-Car eliminate the sound bursts and let me hear signifcantly lessen jitter in one swell swoop?

Hals_den - This is the first time I've heard the "sound burst" complaint from an AE. Since it only happens between tracks, this is at least a clue. I need to know if it ever happens when playing long playlists or only when manually selecting a new track. Also, are you double-clicking on the track or using the mouse select and then the play button?

If it is the iTunes player injecting these, then the Pace-Car will probably not eliminate them. It is probably bad data bursts and the Pace-Car just sends through whatever data you input to it.
