This ensemble has the brand new SP400 amp, which achieves THX AAA-888 quality, outstanding SINAD measurements, features a much larger display screen, and has a full-function remote. It’s paired with the M400 DAC, which has MQA decoding and a high-end power supply, and the package is wrapped up with an interconnect cable and your choice of headphones.

The Gustard-16 Ensemble is a combination of the X16 DAC, H16 amp, an interconnect cable, and finished up with your choice of headphones. The stars of the Gustard-16 Ensemble are the Gustard X16 DAC and the Gustard H16 headphone amp. The H16 has a top quality SINAD rating as well enough power to jumpstart your ears, while the X16 is a novel amp that has the first-ever DAC chip that has built-in MQA rendering for your audio files.
