Muse HiFi M5 Ultra Bluetooth Portable DAC & Amplifier

The 6418 Hi-Res Architecture
The most common issue with Tube-based amplifiers is the signal interference. They usually have electromagnetic interferences mostly around wireless devices. In order to solve this, Muse HiFi has worked closely with ESS factory to customize their “6418” version of the ES9038Q2M chips. This 6418 Architecture solves the interference caused by the Bluetooth signal transmission and ensures clean output signal free from any background and current noise interferences. So you are getting the goodness of a high-resolution ESS Sabre DAC chipset along with tube amplification on the M5 Ultra.

Tube Shock Absorber Technology
We have devoted ourselves to the research and development of shock absorbers for JAN6418 electronic tubes, and designed a complete set of shock absorber solutions for JAN6418, including customized rubber components and component suspension technology, so that the electronic tubes can receive all-round buffering and absorption during use, and the current can be more stable. Achieve "0" stethoscope effect.

New Digital Audio Purification System
A new self-developed digital audio purification system, equipped with two Accusilicon AS318B series 45.1584MHz/49.152MHz, provides a high-precision, low-jitter unified clock source for the entire "6418" architecture, and deeply reorganizes the audio data through customized circuits to make the audio more pure.

QCC5125 Latest Bluetooth Technology
Qualcomm's latest 5125 chip, dual DSP and dual-core CPU architecture to ensure the dual stability of Bluetooth audio and system operation, support LDAC/aptX Adaptive HD Bluetooth coding.
