Unboxing and Build Quality
The Muse M5 Ultra arrives in premium packaging, immediately setting a high-end tone. Upon opening, the device itself is striking, with a transparent panel showcasing the internal audio PCB. This design element is a nice touch, adding a visual appeal that's often missing in portable amps.
The included accessories are thoughtfully presented in a drawer compartment. A navy blue leather pouch, a welcome addition at this price point, perfectly fits the unit and enhances its overall feel. The package also includes a USB-C to USB-C charging cable, a USB-C to Lightning cable, and a USB-A to USB-C adapter for broader compatibility.
Design and Features
The M5 Ultra boasts a sleek aluminum body with glass panels, highlighting the vacuum tubes within. The left side features an ornamental grill, not only visually appealing but likely aiding in heat dissipation. Controls are conveniently located on the right-hand side, including power, volume, and a menu button with arrow keys.
Connectivity options are comprehensive, including a 3.5mm jack, a 4.4mm pentaconn connector, and two USB-C ports (one for charging and one for audio input). The monochrome display is straightforward, showing bitrate and functionality, and is easily navigable via the buttons.
The device offers two amplification modes: transistor and vacuum tube. The vacuum tube mode utilizes dual miniature JN6418 tubes, adding a unique character to the sound. The unit also incorporates shock absorption to mitigate issues associated with portable tube amps.
Sound Quality and Performance
In transistor (TM) mode, the M5 Ultra provides a balanced sound signature with controlled bass, neutral mids, and detailed treble. It offers a similar tonal balance to the Q-style M15C but with slightly less energy and dynamic impact.
Switching to vacuum tube (VT) mode introduces a subtle yet noticeable shift. The sound becomes more organic, with a richer midrange and a smoother treble. Voices and instruments feel more present and realistic, while the bass retains its quality with added warmth.
Both modes perform exceptionally well with various headphones, and the VT mode particularly shines with acoustic and jazz music. Notably, the M5 Ultra effectively mitigates any hiss or interference, even with sensitive IEMs, attesting to its design and implementation.
Conclusion
The Muse M5 Ultra is a well-executed portable tube amp offering a unique listening experience. Its build quality, premium features, and dual amplification modes distinguish it from the competition. The vacuum tube mode adds warmth and realism that enhances various musical genres.
While not surpassing the legendary Chord Mojo 2 in overall sound quality, the M5 Ultra compensates with its built-in Bluetooth, making it a more convenient and versatile option. The additional features and portability factor make it a strong contender in the portable audio market.
At $300, the M5 Ultra is a worthwhile investment for audiophiles seeking a high-quality portable amplifier with the distinct character of vacuum tube amplification. The absence of audible hiss, even at high gain, is commendable. It's a truly unique and enjoyable experience
