Hi-Fi+ has just posted the first of their High End Vienna show reports. Here's what they have to say about MOON's new 491 network player preamplifier and the 461 power amplifier: "It would have been easier for Moon to take the popular 371 integrated streaming amplifier from the Compass range and split it into two separate components. Instead, Moon listened to its better angels and went with a vastly more flexible and powerful pairing. With all the inputs and outputs you could ever need and a highly flexible MM/MC stage, the £5,950/$6,500 491 uses the more sophisticated volume control and hybrid linear/switch mode power found on the brand’s higher-end devices. Meanwhile, the £4,450/$5,000 power amplifier uses even more of the hybrid power supplies to deliver its 150W per channel. This can be driven in bridged or bi-amp mode. While we’ve said we won’t be discussing sound too much at this show as it’s new to everyone, this system – coupled with Dynaudio’s Contour Legacy loudspeakers and Nordost Heimdall 2 cables – was a true star, with plenty of drive and energy."

The next few weeks are going to be exciting, as we have three major new products arriving: Audiovector's R 5 Arreté loudspeaker, the MOON 491 network player preamplifier and the MOON 461 power amplifier. Each features technology derived from products further up the range and represents excellent value. Next stop: the High End Vienna show for their global launches. We'll keep you posted.

John and our PR man Matt travelled way down south to visit Paul Miller of Hi-Fi News and his excellent listening facility. They delivered the magnificent MOON 891 network player preamplifier and MOON 861 power amplifier for Paul to assess. The combination sounded superb in Paul’s custom-built room and we look forward to reading his review when it is written. We'll keep you posted. MOON by Simaudio

Here’s all you need to know about MOON by Simaudio's mighty new 461 power amplifier. The MOON 461 is designed to amplify the signal from a preamplifier with absolute accuracy. As the most powerful model in the Compass Collection, it is engineered to deliver substantial output capability, low distortion, and stable performance across a wide range of loudspeaker loads, while preserving the signal integrity with transparency, dynamic expression, and composure under demanding conditions. At the heart of the 461 is proprietary MOON Distortion-Cancelling Amplifier (MDCA) architecture, pioneered in the flagship North Collection. This advanced topology significantly reduces distortion and improves linearity, contributing to a highly faithful rendering of the source signal with exceptional clarity and accuracy. Two proprietary MOON Hybrid Power (MHP) supply modules - one dedicated to each channel - provide a stable, low-noise, and high-current energy source to the amplifier. This dual-mono implementation improves channel separation, lowers crosstalk, and enhances current delivery, particularly into lower-impedance loads. A Stereo / Bridged Mono / Bi-Amping Mono mode switch expands installation flexibility and supports a wide range of loudspeaker configurations. With its black chassis, bead-blasted aluminium cheeks (available in black or silver), and clean architectural lines, the MOON 461 combines robust engineering with the distinctive visual language of the Compass Collection. www.renaissanceaudio.co.uk/moon/p/461

Here’s what you need to know about MOON by Simaudio’s magnificent new 491 network player preamplifier. The MOON 491 is a fully equipped network player, preamplifier, DAC, phono stage, and headphone amplifier designed to handle digital and analog sources with precision and versatility. As a key component in the Compass Collection, it is engineered to deliver broad connectivity, low-noise performance, and seamless streaming and digital conversion, while preserving signal integrity with clarity and refinement. At the core of the 491 is MOON’s proprietary MiND 2 streaming technology. It can operate as a UPnP renderer, a Roon Ready endpoint, and is compatible with AirPlay and Bluetooth. The MOON MiND Controller app for iOS and Android provides access to major music services including Qobuz, TIDAL, Deezer, and Spotify. Playback and system functions can be controlled through the app, the front-panel buttons, and the aluminium CRM-4 remote control. The 491 also supports Qobuz Connect, TIDAL Connect, and Spotify Connect. The integrated phono stage supports both MM and MC cartridges configurable via the on-screen menu for loading, capacitance, gain, and equalization options. This adaptability enables cartridge matching for optimized vinyl playback. The balanced analog preamplifier features two line-level inputs - one RCA and one balanced XLR - and one phono input. Output is via variable and fixed RCA connections, and a variable balanced XLR connections, as well as a ¼” headphone jack. The large display indicates volume, album art, and other information in brilliant colour. The 491 employs proprietary MOON Hybrid Power (MHP) technology, blending linear and switch-mode technologies for ultra-stable, low-noise DC power. Operating at switching frequencies beyond the audio band, it avoids contaminating highly sensitive audio circuits, resulting in a lower noise floor with greater dynamic swings. Housed in MOON’s signature black chassis with bead-blasted aluminum cheeks (black or silver), the 491 blends cutting-edge engineering with timeless style.

We are delighted by the launch of two major additions to MOON’s Compass Collection: the MOON 491 network player preamplifier and the MOON 461 power amplifier. The MOON 491 is a fully featured network player, preamplifier, DAC, phono stage and headphone amplifier built to serve as the hub of a high-performance audio system. It offers a full range of streaming options through the proprietary MiND 2 platform. The integrated phono stage supports both MM and MC cartridges and allows fine adjustment, while the large colour screen displays settings, album art, and track details. The sleek CRM-4 metal remote ensures effortless control. The 491 partners with the Compass Collection’s most powerful model, the MOON 461 power amplifier. The 461 has substantial output capability (150W per channel), exceptionally low distortion, and stable performance across a wide range of loudspeaker loads, while preserving signal integrity with transparency, dynamic expression and composure. Our MD, John Carroll, says: “Together, they deliver outstanding musical performance and system flexibility, while also making a visually striking statement that will look exceptional in any environment, from contemporary interiors to traditional spaces.” Follow the links for more details: https://www.renaissanceaudio.co.uk/moon/p/491 https://www.renaissanceaudio.co.uk/moon/p/461
