The new Zdac v.2 builds on the Zdac's acclaimed sound quality plus important new features. The Zdac v.2 sounds natural and less "digital" than more expensive DACs thanks to our asynchronous sample rate converter. A precise re-clocking system eliminates bitstream-contaminating jitter that's picked up along the digital signal chain. Unlike many other DACs, the Zdac v.2 eliminates jitter on all of its inputs (not only the USB input).
