The SimAudio Moon Neo 390 features a compact design that integrates a DAC, preamplifier, headphone amplifier, phono preamplifier (MM/MC), and a streaming component. It does not include a built-in power amplifier, necessitating a connection to either active speakers or an external power amplifier. This model is derived from the 350P preamplifier and 380D DAC, merging their capabilities while introducing several key enhancements. Notably, it allows access to music from streaming platforms such as Tidal Masters, Qobuz Sublime+, and Deezer Hi-Fi. The integrated converter is capable of handling PCM up to 32 bit/384 kHz, DSD256, and MQA formats.
The device is Roon Ready certified and features a Bluetooth module with aptX technology. The manufacturer highlights the integrated MiND2 streamer, which supports a variety of popular audio formats and enables streaming from local storage and USB drives. The MiND2 module can transmit any signal, whether from digital or analog inputs, to two identical wireless modules in different zones simultaneously.
Similar to other models in the new Neo series from the Canadian brand MOON, the SimAudio Moon Neo 390 preamplifier incorporates technical and design elements found in the premium Evolution series. When paired with one of the power amplifiers from the Neo line, users can expect a notable enhancement in audio quality compared to integrated amplifiers, particularly in terms of realism, dynamics, richness, and accuracy of timbre reproduction. Audiophiles will appreciate the meticulously designed discrete headphone amplifier section. Additionally, the preamplifier includes a digital-to-analog converter module, facilitating direct connections to digital sources such as computers, DVD or Blu-ray players, and iPod docking stations. For vinyl enthusiasts, an MC/MM phono stage is also available.
SimAudio Moon Neo 390 encompasses essential features, including compatibility with the SimLink connection protocol, a 12 V trigger input, an RS-232 port, and IR ports for seamless integration into smart home systems. Its impressive dynamic and frequency ranges enable the preamplifier to effortlessly reproduce high-resolution audio recordings. The versatile rear panel design facilitates straightforward connections to nearly any audio component.
The preamplifier’s power supply utilizes two toroidal transformers, each rated at 10 VA, along with a capacitor bank totaling 26,400 μF. Signal levels are managed by a motorized potentiometer, making it inaccurate to suggest that it could be effectively substituted by a board in the DAC. Additionally, the preamplifier features a built-in headphone amplifier. It is worth noting that the DAC boards for both the transport and preamplifier appear to be constructed from different component bases, so a comparative listening test is necessary to determine preference. The SimAudio Moon Neo 390 digital-to-analog converter is designed around the proprietary M-AJiC 32 circuit, which functions in a fully asynchronous 32-bit mode. This circuit incorporates the renowned ESS SABRE 32 Ultra DAC chip, equipped with Hyperstream technology, allowing for the utilization of eight DACs (integrated within this chip) for each playback channel during the conversion process.
The SimAudio Moon Neo 390 features a comprehensive array of digital inputs, including 4 HDMI ports, 2 XLR AES/EBU connections (with one dedicated to AES/EBU), 1 optical input, and 1 USB port. All inputs are capable of handling audio resolutions up to 24 bit/192 kHz. Additionally, the MOON 390 is equipped with a fully digital signal loop Monitor Loop, allowing for the connection of external digital devices, such as a digital signal processor for room correction.
This DAC supports DSD formats up to DSD256 and PCM up to 384 kHz. It includes USB and Ethernet/WiFi connectivity, along with analog outputs that offer both fixed and variable signal levels. The choice of output depends on whether the user employs a preamplifier or connects the DAC directly to an amplifier. The SimAudio Moon 390D Streaming DSD DAC also allows for factory firmware updates and hardware upgrades as needed.
Now, let’s examine some key components of this DAC. The MiND network board and volume control are part of the MiND package, which is now included in the standard 390 offering. The M-eVOL volume control board featured in the 390 is the same as that found in the premium Moon Evolution series.
There are numerous methods available today for streaming music via IP to your DAC. Some manufacturers opt to integrate ready-made solutions from third-party providers into their DACs, while others create external devices that facilitate the conversion of streams for AES or USB inputs. Simaudio, for instance, produces its own network adapter for its Moon product line and has recently launched an iOS app, with an Android version in development. Simaudio’s preference for in-house production is evident in the high quality of their work, as demonstrated by the new iOS app. The previous iteration, developed by an external party, was subpar, whereas the latest version features a clean design that enhances user experience. Simaudio refers to this entire system—including the network card, streaming capabilities, and software—as the MOON intelligent Network Device (MiND).
When integrated with a device like the Simaudio Moon Neo 390, MiND transforms it into a UPnP/DLNA player. This functionality enables MiND-equipped Simaudio components to communicate with various UPnP/DLNA servers and control devices. The most straightforward setup using the 390 DSD as a client involves utilizing the iOS app as a control interface alongside UPnP server software on a computer or NAS (Network Attached Storage). During my evaluation, I explored several configurations, including the aforementioned setup and one that utilized JRiver Media Center as the server and JRemote as the control interface. While the JRiver/JRemote pairing offers greater capabilities, it also presents a more intricate setup process.
The MiND iOS application developed by Simaudio is user-friendly and suitable for even the most inexperienced users. The app simplifies the process of selecting an existing MiND component by automatically detecting it on the network. It provides details such as the IP address of the Simaudio device and the firmware version, although this information is likely unnecessary for most users. By clicking the “Update firmware” button, the MiND app manages the update process autonomously. However, a notable drawback is the absence of a progress indicator during firmware updates. The installation screen also displays information for connecting to the WiFi network. For more experienced users, it is worth noting that MiND supports WiFi data transfer standards up to 2.4 GHz 802.11n, accommodating both public networks and those with a hidden SSID (Service Set Identifier). Overall, the settings are straightforward, and beginners need not delve further.
The next feature of the iOS application we will discuss is the selection and playback of tracks. Users can easily choose their preferred UPnP / DLNA server from a convenient drop-down menu, eliminating the need for any additional server information. Simaudio has streamlined the process of selecting and enjoying music, allowing users to find and play their desired content instantly or add it to the beginning or end of the playback queue.
Alternatively, users can opt to play it next. Once the playlist is created, tracks can be removed individually or all at once, and the playback order can be adjusted as needed. While the selection of tracks may not be extensive, the process remains straightforward. It is also important to highlight two features that are not available with third-party applications like JRiver / JRemote: the ability to control volume and select the active digital input directly through the iOS app. The sound control functions similarly to using an IR remote, with the key difference being that the control signal is transmitted over an IP network. Overall, I rate the new app highly for its user-friendliness, simplicity, and its capacity to enable users to enjoy music without requiring advanced technical knowledge.
Simaudio excels in creating durable products that remain relevant despite the introduction of new models. The SimAudio Moon Neo 390 alleviates any concerns previously mentioned, allowing users to experience outstanding sound quality. This product is highly recommended for audiophiles who struggle with indecision, uncertainty, and anxiety regarding sound performance. Please note that extended listening sessions exceeding four hours are common with Simaudio equipment.
