But for diyers, there is always something to mod 🙂įor this model of AE, tapping into the I2S signals is not feasible since it is based on the PCM2705 which only supports SPDIF output. With multiple built-in switchable inputs available in the Sabre-32 DACs which are easily implementable under software control, there is even no need for an external switching device.Ĭertainly no modding is necessary since the AE already has a Toslink output.
Now, adding an additional “Airplay” input to the audio system is a desirable option, especially for an “iOS household” like mine.
I have been contemplating modding the Airport Express since at least 2009, but never got around doing it. Its performance can be enhanced several notches if the I2S digital output can be tapped. “The beauty of this unassuming component,” said JA, “is its S/PDIF data output, which allows the Airport Express to assume a respectable role in a true high-end audio system.” However, its lack of an internal clock can lead to the first couple of seconds of songs being missed with DACs that are slow to lift their mutes.
While the Airport Express works only with iTunes v4.6 or later (running on both PCs and Macs), is limited to 16-bit data, and functions only at a 44.1kHz sample rate, the combination of iTunes and the Airport Express offered an easy way to pipe CD-quality music around the entire home.
