The FiiO M23 Digital Audio Player and K19 Desktop DAC/Amplifier will be on show at CanJam, New York on Saturday & Sunday March 9-10th 2024.

The new M23 Digital Audio Player (DAP) builds upon the success of previous award-winning portable audio equipment from FiiO. Featuring the flagship AKM AK4191EQ + AKM AK4499EX DAC combination, the M23 supports playback of audio files up to, and including, 24-Bit 384kHz PCM/DSD256, and also supports files encoded using MQA.

Alongside physical 3.5mm single-ended and 4.4mm balanced headphone outputs, and both single-ended/balanced line-outs, the M23 is able to both transmit and receive Hi-Res audio thanks to aptX HD Bluetooth and LDAC wireless connectivity. This two-way connectivity means not only are wireless headphones catered for, but the M23 can also receive audio from a smartphone, PC or other device and be used as a Bluetooth DAC/Amplifier.

Featuring a Dual Power supply, when using external USB power, the M23 features a ‘Desktop Mode’, allowing this versatile product to perform well as a both a portable and desktop device. In Desktop Mode, the ‘Super-High’ gain level is available, allowing the M23 to deliver an impressive 1000mW per channel @32Ω.

In addition, when using the internal battery, the ‘HiFi Boost Mode’ function can be enabled in settings which provides the option of higher output power when using the M23 in battery mode. If required — using the balanced headphone output @32Ω — the M23 is able to deliver up to 760mW in ‘High Gain’.

Equipped with the powerful Qualcom Snapdragon 660 processor the M23 runs on a customised Android operating system and features a global SRC bypass, meaning music streaming apps such as TIDAL, Qobuz, Apple Music, Deezer and more can be installed to allow listening in full lossless quality.

Available in either Blue Titanium or Stainless Steel, the M23 offers up to 10.5 hour battery life, 5.5" multi-touch HD display, and onboard storage of 64GB. For those wanting to carry more of their music files around with them, M15S also features a micro SD card slot with support for up to 2TB cards.

FiiO M23 launches in April and is available to pre-order now, priced £649 / €700 / $700 for the Blue Titanium model; £799 / €849 / $899 for the Stainless Steel model.
