Dossier — JadeAudio JA11
The brochure speaks; the silicon answers. What follows is what each has said.
+ Vendor page › +This product enumerates under more than one USB identity; each is witnessed against its own descriptor below.

| DSD via DoP (DSD64 / DSD128) | Silent | DSD is delivered via the DSD-over-PCM (DoP) transport, which rides on PCM alts at marker rates (176.4 kHz for DSD64, 352.8 kHz for DSD128). The descriptor cannot directly witness DoP capability as a distinct alt — see Remarks. | — Silent: claims unwitnessable by descriptor |

Remarks
While the JA11 performs in accordance with the published technical specifications, the marketing images and listings are imprecise when they state DSD128. The JA11 does not render DSD natively; DSD can only be delivered through the DSD-over-PCM (DoP) transport.
