The finest sounding and most complete “all-in-one” available, the ACE can do virtually anything expected of a high-performance audio component of this nature. Accentuated by our world renowned MOON sonic signature – visceral tight bass, transparent midrange, precise natural highs – along with lifelike sound, plus countless features, the ACE will be the “heart and soul” of all your musical indulgences.

The ACE is both intuitive and easy to use. Bridging digital and analog audio at a price/performance ratio that is impossible to beat, the ACE includes a high resolution DAC with DSD decoding up to DSD256 and 32-bit/384kHz PCM.

MiND 2 streaming module is Roon Ready and allows the playback of all the most common file formats, including DSD, and MQA file formats (via local files and TIDAL Master files).

System sprawl: the curse of too many components and too much technology. It begins innocently enough with a sagging equipment rack. The sprawl then takes prisoner of precious floor or shelf or closet space until, in its advanced stages, it becomes an environmental threat to happiness, even sanity in many an audiophile’s home. We’ve all been there. But if you are of a mind, there is an alternative. It’s the integrated solution, a clarion call to downsize, to de-clutter, and to economize that might just prevent a range war with that significant other. Few components do it better, or have more fun doing it, than the Moon ACE all-in-one music player.

The résumé of the ACE is broad, but at its heart lies a compact stereo integrated amplifier that outputs 50Wpc into 8 ohms and 85Wpc into 4 ohms. The actual significance of a power rating is always a matter of conjecture, but Moon products are typically conservative in their measurements. The Ace’s 50W is the more forthright RMS rating—both channels continuously driven, full-range from 20Hz–20kHz. This power gives the ACE the ability to handily drive speakers that are more difficult loads.

For prospective owners, 50Wpc with good headroom means a fairly wide latitude in speaker selection. For this review the ACE comfortably drove the Emotiva Airmotiv T1 floorstander (review forthcoming) and the Totem Acoustic Sky compact (Issue 275). It even took a shot at the demanding TAD ME1 compact.

Handsome and low-profile, the ACE’s exterior design is elegantly turned out using a blend of aluminum and steel. The center faceplate for example is expensive 6063 aluminum, an excellent surface for brushed and anodized finishes. The ACE’s combination of metal work serves dual purposes: The aluminum contributes to a reduction in weight, and the steel top cover provides chassis reinforcement. The front-panel layout is clean and concise with input and set-up push-button controls, a 3.5mm mini-jack input for a personal music player, and a ¼” jack for headphones. A sharp OLED-type screen display is very readable and informative. A chunky volume control adds a bit of old-school tactile charm often lacking in today’s dry computer-tronic landscape.                                                                                                      READ MORE
