Quoted from the review :-
".. Calyx’s DAC 24/192 is a beautifully built, elegantly styled digital-to-analog converter that sounded exceedingly neutral and utterly clean in my system. It’s also capable of very high resolution that’s just shy of the very best -- I wouldn’t hesitate to partner it with some of the finest equipment out there, regardless of price..."
