I've compared this using a Chord Blu Transport and Airport Express into a Chord DAC64. Without the buffer (i.e. jitter reduction) circuitry turned on, the transport had a deeper, richer sound. Engaged the buffer up to 4 seconds and you'd be hard pressed to tell the two apart. Three people were in the room (including the Chord dealer) and we all agreed the Airport Express with a top-quality DAC changes the landscape in high-end audio. Source was both Apple Lossless and direct from CD through iTunes on an IBM Thinkpad T42.
In the end, I wound up using a USB extender to an M-Audio Audiophile USB with coaxial out into a Musical Fidelity A3.2/24 DAC. The Chord was a great unit, but I just didn't want to spend that much as my system is still in experimental mode.
