UAPP also supports MQA via an in-app purchase. UAPP supports Tidal, Qobuz and Google Music but offline content is prohibited, not by the streaming services but by rights holders (aka labels).Ħ.

The workaround is to use a third-party app for music playback: USB Audio Player PRO (UAPP) loads its own USB driver and its bit-perfect mode sidesteps Android’s software volume control and any associated re/up-sampling. The Xiaomi Mi A1 displays similar behaviour. It is not bit-perfect, thus red-carding MQA, which it also resamples to 48kHz.

However, stream the same Sigur Rós from Tidal with the AudioQuest DAC connected to the LG V40 smartphone and Cobalt’s light glows blue - a 48kHz stream! This tells us that the Android OS is upsampling the digital audio stream before it is dispatched via the phone’s USB socket. When the DragonFly Cobalt is connected to an iPhone using Apple’s Lightning-USB adapter (sold separately) and called upon to decode Sigur Rós in CD quality content from Tidal, the Cobalt’s light glows green, indicating the presence of a 44.1kHz data stream.

Once inside the Cobalt, the in-built MQA code executes further unfolds, should they exist, and also MQA rendering.ĥ. The MQA stream then enters the DAC at 88.2kHz or 96kHz and within the USB receiver chip’s limits.
The first unfold is executed in software running on the host device. Higher sample rates are possible when streaming MQA to Cobalt. The 96kHz ceiling is a side effect of its USB Class 1 status that permits full, driverless compatibility with Android, iOS, Windows, MacOS and Linux.Ĥ. This is a not a limitation of the ESS 9038Q2M DAC chip (which can handle PCM sample rates up to 384kHz) but of Microchip’s USB receiver. On hi-res audio support, Cobalt is limited to 96kHz PCM. The Cobalt trades in some of the Red’s sonic (the hedgehog?) get-up-n-go for a more masterful command of dynamics.ģ. Cobalt’s USB receiver chip is different and its DAC chip is different.
The Cobalt isn’t just a Red front-loaded with AudioQuest’s own Jitterbug. Ergo, Cobalt, like Red and Black, is a DAC / headphone amplifier.Ģ. The DragonFly’s output doesn’t come straight off its ESS DAC chip from an interceding ESS 9601 headphone driver chip. Here are ten thoughts that didn’t make the final cut of our short film about AudioQuest’s DragonFly Cobalt:ġ. For some veteran audiophiles, that’s all part of the fun but for newcomers, too much tech talk is a turn-off.īack on the mothership (this website), we can go for a deeper dive on those details. In scripting, shooting and cutting a short film about an audio product, our intent is for the bigger picture not to be lost to the details that can otherwise cause the pursuit of better sound to be seen as an elitist geek fest. The top two watchwords of the Darko.Audio YouTube channel that, as of this week, is now attracting as many unique visitors per month as the Darko.Audio website: 250,000 apiece.
