In this review, however, we’re sizing up Simaudio’s Moon 280D DAC, which features its MiND 2 (Moon intelligent Network Device) wireless-capable music streaming module. With a $3,000 price tag, the 280D falls squarely within the mid-level price tier for the streaming DAC category. Given the intense competition in that space, I was curious to see what, if anything, would cause the 280D to stand out from the pack.
The Moon 280D is not a completely new product for the company. It was first introduced in 2015 and has been continually updated, with the MiND 2 module added in 2018. The most recent updates bring Spotify Connect and Apple AirPlay 2 support.
A fully asynchronous DAC, the Moon 280D’s ESS Technology Sabre ES9018K2M chipset is capable of processing PCM signals up to 32-bit/384kHz (including DXD) and native DSD64, double DSD (DSD128), and quad DSD (DSD256) signals, which are supported only through the USB and network (LAN/Ethernet or Wi-Fi) inputs. The 280D also fully unfolds Master Quality Authenticated (MQA) files arriving via its network inputs.
Signals streamed over a wired or wireless connection from local UPnP servers and internet-based music services are handled by the MiND 2 module, which is controlled via the Moon MiND 2 iOS or Android controller app. A separate module in the Moon 280D handles aptX Bluetooth wireless streaming.
The MiND 2 module is Roon Ready and supports Tidal, Deezer, Qobuz, and internet radio streaming, while Spotify is supported via its native app and the Spotify Connect function. Apple AirPlay 2 allows other music services to be streamed via their native apps. Lastly, the MiND 2 module permits synchronized multiroom playback on multiple MiND 2-equipped devices, with zones grouped together or run separately.
The 280D in my estimation easily rubs shoulders with the very best network music players at its price level.
Recent updates to the Moon 280D added Spotify Connect plus AirPlay 2 support for wireless streaming from an iOS device.
On the analog side, the Moon 280D features fully balanced differential circuitry and four-layer printed circuit boards with pure copper tracings. Careful attention has been paid to the 280D’s circuitry layout. For example, the clock has been closely positioned to the DAC chipset, while separate voltage regulators are used for the digital and analog sections.
The Moon 280D’s front panel consists of a 1/4-inch-thick aluminum plate flanked by a pair of side “cheeks.” Color options include black, silver, or two-tone (e.g., a black centerpiece with silver cheeks). Simaudio’s treble clef logo is positioned in the middle, above a blue LED power indicator and a standby button. On the left side are buttons for Bluetooth activation and input selection, along with a group of red LED indicators that show the active input, while the right side holds the second group of red LED indicators showing PCM sampling and DSD data rates. There’s no front-panel display, as Simaudio feels the listener will typically be sitting a good distance away and have album art and track information available via the Moon MiND controller app. There’s also no volume control, though both features can be found on Simaudio’s upper-level streamers, including the 280D’s big brother, the $5,900 Moon 390 network streamer/preamplifier.
