Key considerations before buying the MOON 791 network player preamplifier, including system fit, features, and trade-offs.
Quick answer
The MOON 791 is a strong choice if you want a single component that handles analog preamplification, DAC conversion, and network streaming without signal degradation. It works best as the center of a high-end two-channel system where simplicity and signal purity matter more than expandability or modular upgrades.
Why integrate preamp, DAC, and streaming in one box?
A combined network player preamplifier like the 791 reduces the number of interconnects, power cords, and boxes in your rack. That can mean fewer potential noise paths and a cleaner signal chain. For many listeners, the convenience of controlling volume, source selection, and streaming from one device outweighs the flexibility of separate components.
The trade-off is that you commit to the manufacturer's design choices for all three functions. If you later want a different DAC flavor or a more powerful preamp section, you cannot swap just one part. The 791 is designed to be a long-term system anchor, not a modular platform.
Analog volume control matters at low listening levels
Many digital preamplifiers reduce bit depth when you turn down the volume, which can degrade resolution. The MOON 791 uses M-VOL3 analog volume regulation, meaning the attenuation happens in the analog domain after the DAC. This keeps the signal full-resolution regardless of listening level.
If you often listen at low volumes—late-night sessions or near-field setups—this is a meaningful advantage. The constant channel tracking also matters for maintaining a stable stereo image at any level.
Decision rules for the 791
- System integration: The 791 replaces a separate preamplifier, DAC, and streamer. If you already own high-end separates, the 791 only makes sense if you are willing to sell them for a cleaner, integrated solution. Check whether your current separates outperform the 791's combined performance before committing.
- Volume control preference: If you listen at a wide range of volumes and want consistent resolution, the analog M-VOL3 is a key advantage. Digital volume controls in many competitors lose bit depth as you turn down. If you mostly listen at one fixed level, this feature is less critical.
- Future upgrade path: The 791 is a fixed configuration. You cannot swap the DAC module or upgrade the preamp section independently. If you like to evolve your system piece by piece, separate components give more flexibility. Plan for the 791 as a long-term system centerpiece, not a stepping stone.
- Streaming ecosystem: The MiND 2 platform handles local files, Tidal, Qobuz, and Roon. If you rely on a different streaming service or require multi-room synchronization, verify compatibility before buying. Confirm that MiND 2 supports your preferred streaming sources and control app.
Product highlights
- 791 Lettore di rete/ Preamplificatore: MOON 791 combines an analog preamplifier, a full DAC, and a MiND 2 network player in one chassis. It uses M-VOL3 analog volume control to maintain constant resolution and channel tracking at all levels. You get a complete front-end in one box without sacrificing volume accuracy or signal integrity, especially at low listening levels.

Who should buy the MOON 791?
Best for
- Listeners building a high-end two-channel system and wanting a single, clean front-end component
- Users who value analog volume control for consistent resolution at all listening levels
- Audiophiles who prefer a dual-mono design for channel separation and noise isolation
Not ideal for
- Those who want to upgrade DAC or preamp separately over time
- Listeners who need multi-room streaming or support for niche services not in MiND 2
