Empirical Audio Freeway I2S and Off-Ramp I2S.

You must make sure of what I2S you need. It comes in a few flavors and voltages. Some need MCLK, some dont. Some need 128fs some need 256fs. Some have two serial data streams (some pro gear).

Kipman,

What Steve is trying to say is I2S is not an external specification. It is an internal specification between say an Audio Receiver (be it USB, Firewire or SPDIF) and a DAC or Processor.

Some companies have made external I2S connections but there is no electrical standard to support them.

Thanks
Gordon

Aside from the offerings from Empirical Audio (which are not really sound cards), no there are none that I know of that support this natively. There are several that can be modded to support I2S output, the Juli@ being one of them.

I am really curious to know what you are connecting the I2S up to. What sort of devices take the input of I2S?

Really? Cool. I'm gonna go look into this.

Edit: Just looked! And it appears the Juli@ has native I2S, no mods required. BUT...might be some modding to get that signal out, though.

You asked about kinds of devices, you didn't ask for specific models. Instead of asking what kinds of devices, you should have asked which DAC's accept it, and how.

Ask a general question, and most of the time you'll get a general answer.
