“I’ve used the Aqua Acoustic Quality Formula xHD, both as a USB DAC and in tandem with the stunning Aqua La Diva transport, basically since the inception of SoundStage! Australia in July 2017. As such, I’ve heard it over the long haul with a wide variety of equipment and it never ceases to amaze – or to inspire the supporting cast. Its inherent neutrality, its refined and revealing nature makes the job easy – and very, very enjoyable. Staging and imaging are pinpoint (and natural), resolution is pinpoint, timing is to die for. Focus, insight and analysis are simply mesmerising. Even now, I have to turn the damn thing off to finish this review.
But if I had to sum it up, the xHD is serene. It has that uncanny sense of purity and natural ease, a stress-free listenability that simply gets me closer to the music, and this not merely for a digital component. The xHD is capable of resolving the finest dynamic gradations, the slightest nuance of a musician’s unique touch, pressure and feel in the most human and, therefore, analogue of ways. Musicians call it their tone. The Aqua gets this masterfully right…” - Peter Katsoolis, SoundStage Australia
