ONIX Waltz XM10 Ltd AK4499EX Portable Android Digital Audio Player

The Miracle Beginning

Original ONIX XM10 was included in the High-End Miracle setup, acting as the streaming platform for the Hi-Fi stack, while being a decently sounding portable player on its own.

Pushing Design Limits of Hi-Fi Players

Optimized for true portability, ONIX Waltz was thinned down to just 11.5mm, putting it closer to standard smartphones and avoiding the unpractical dimensions of bulky Hi-Fi Players. At the same time, its build was further enhanced by utilizing stainless steel construction

Serious Audio Performance

ONIX Waltz takes inspiration from ONIX Mystic XP1, creating a naturally sounding player based around AKM’s flagship DAC system, AK4499EX DAC and AK4191 ΔΣ modulator. Supported by the in-house developed “Brighton” I/V conversion circuit and FPGA technology.

While ONIX Waltz features only a 3.5mm socket, Balanced output can be achieved with the provided 5-pin 3.5mm to 4.4mm Balanced adapter.
