Another interesting product featured in the Canada Pavilion was the exaSound e18DAC ($1999). It is, as the name implies, a DAC, but it's much more than that. Featuring a maximum 384kHz/32-bit sample rate and bit depth, it can function in stereo and 8-channel modes, and has a formidable list of technical specifications, including a 0.13ps master clock with 3 precision quartz oscillators, 17 power filtering stages, galvanic isolation between the USB subsystem and the DAC circuits, true asynchronous USB interface, hardware volume control implemented by the DAC chip for the highest S/N ratio, and has a high-quality headphone amplifier.
