ALL-IN-ONE EFFORTLESS MUSIC STREAMING
The MSA5500 Streaming Integrated Amplifier is both a full featured music streamer and powerful integrated amplifier in one. It can serve as the cornerstone of your audio setup, whether it be your first venture into high-fidelity audio, an addition to your existing system, or to use at your office or vacation home. Crafted to perfection and compact in size, the MSA5500 is tailor-made for modern living spaces, making it an ideal choice for those seeking premium audio in more confined environments.
The versatile MSA5500 has a wide assortment of wireless music streaming capabilities plus a variety of physical inputs to connect source components. If all your music is cloud based digital music, a simple addition of speakers is all that's needed to be bathed in elevated sound quality.
"It will deliver everything that the high end should in terms of how it looks, feels and sounds, and that includes a bit of visual drama while it does it. It combines the classic flourishes with a real world user friendliness that would have been impossible to conceive of even comparatively recently." Named Best High-End All-In-One Hi-Fi System 2025/2026. - AVForums
ENDLESS STREAMING POSSIBILITIES AWAIT
The MSA5500 is compatible with a multitude of leading streaming technologies and platforms including Apple® AirPlay®; Bluetooth®; Google Cast™ (formerly Chromecast); Qobuz Connect; Spotify® Connect (including Spotify Lossless); and TIDAL® Connect(including TIDAL Max). No special control app or technical skills are needed; the easy-to-use MSA5500 invites you to simply stream your music directly from your smart device.1 If you've been using a lower quality wireless home sound system, then listening to your favorite tracks through the MSA5500 will be like hearing them again for the first time.

For Bluetooth streaming, the MSA5500 utilizes Bluetooth 5.0; the high bitrate Advanced Audio Coding (AAC) standard; Qualcomm® aptX™ HD for hi res audio playback; and Qualcomm aptX Adaptive, a robust solution that delivers high resolution, uninterrupted audio over Bluetooth. Two Wi-Fi 6 antennas and one Bluetooth antenna provide stable wireless connections, while an Ethernet port is also available for wired connections.
STREAMED MUSIC HAS NEVER SOUNDED SO GOOD
To elevate your auditory experience of your digital music, the MSA5500 employs an audiophile-grade digital-to-analog converter (DAC) to convert digital signals into the analog format needed for playback. This next generation, Quad Balanced, 8-channel, 32-bit DAC features huge dynamic range and low distortion. Regardless the file format, you can expect a transcendent audio experience with pristine sound reproduction.
"If you have been using a ‘just add speakers’ style all-in-one at a [lower] price point, this system will give you the same breadth of convenience and flexibility as what you’re used to – but with a level of performance and presence that is beyond anything you’ll have experienced before." - Sound Advice
The MSA5500 has received Roon Ready certification from Roon Labs, making it an endpoint device for use with the Roon music player. Roon brings all your music together and adds tons of data – bios, reviews, photos, lyrics, tour dates, and cross-linked credits for performers, songwriters, producers, engineers, and composers. Roon Ready network devices have Roon streaming technology built in and are certified by Roon to provide the highest level of quality and performance in network streaming.It has also received Roon Tested certification as Roon has profiled it to ensure simple setup and effortless daily use.
ALL THE CONNECTIONS YOU NEED
In addition to all its streaming capabilities, the MSA5500 also comes 7 digital and 5 analog audio inputs to connect audio components, such as a CD playeror tuner, plus a Moving Magnet phono input to connect a turntable. The digital inputs support high resolution digital audio playback; the USB input supports native playback of DSD512 and DXD up to 384kHz, while the coax and optical inputs can decode digital music up to 24-bit/192kHz.

UNRIVALED TV SOUND
The inclusion of an HDMI (ARC) input lets you connect your compatible TV so you can enjoy your favorite shows and movies with a sound quality level that TV speakers or soundbars just can't provide.2 Popular multi-channel audio formats from Dolby® and DTS® will be expertly converted to two-channel audio for proper playback. The subwoofer output allows for a powered subwoofer to be added for extra punch so you can feel every bass and low-end note.

HEAR SOUND LIKE NEVER BEFORE WITH UNCOMPROMISING MCINTOSH AMPLIFICATION
The power amplifier section of the MSA5500 proves that extraordinary sound knows no bounds. Delivering 100 Watts per channel into 8 Ohm speakers or 160 Watts per channel into 4 Ohm speakers, this amplifier ensures ample power delivery for a diverse array of speakers, such as our vintage styled ML1 Loudspeaker Mk II, XR50 Bookshelf Speakers, XR100 Floorstanding Speakers, or a variety of other speakers. Real-time power output is visualized through fast responding, dual-scale Watt meters in our trademarked McIntosh "Blue" color, affording insight into the amplifier's performance.
"This McIntosh possesses the rare ability to overcome the challenges set for it with ease, breathing life and depth into performances, from the finest nuances to unmentionable levels, in order to offer a realism that very few electronics can express with such ease and conviction.” - Haute Fidélité
An arsenal of other McIntosh technologies is included that will contribute to the MSA5500's longevity and reliability:

ACCOMODATES YOUR CHANGING NEEDS
As your audio needs evolve, the MSA5500 can grow with you. Someday you may move into a bigger space or add a larger set of speakers and find that you need more power. If that happens, you could bypass the internal amplifier and connect a bigger external amplifier – all while continuing to use the MSA5500's familiar streaming and preamplifier sections. You can rest assured that the MSA5500 can accommodate your changing needs and be a lifelong partner in your audio pursuits.

Here, there's no affectation, no unnecessary complexity; the music fills the entire space and comes to life instantly." Winner of Diapason d'Or Hi-Fi Award - Diapson Magazine
