FiiO Jade Audio LEVEL 1 Hi-Res Power Amplifier

The FiiO Jade Audio LEVEL 1 is a notebook-sized stereo power amplifier for passive speakers, built around Texas Instruments’ TPA3255. With the included 48V/5A adapter it delivers 120W per channel into 4Ω, and with a larger supply it reaches 300W per channel. Bluetooth 6.0 with LDAC, a USB DAC, coaxial and analogue inputs, analogue bass and treble knobs, and subwoofer and pre outputs make it the hub of a compact hi-fi system, in an aluminium case with real wood side panels.

Small footprint, serious power

Despite its 181 × 133mm footprint, the LEVEL 1 can drive most mainstream passive bookshelf, desktop and floor-standing speakers of 4–8Ω. How much power you get depends on the power supply:

The headline 2 × 300W figure needs a supply of 600W or more. The included 240W adapter is certified to international safety standards, with ultra-low ripple and plenty of current in reserve for a low noise floor and consistent dynamics.

TPA3255 with PurePath Ultra-HD and PFFB

At the heart of the LEVEL 1 is the TI TPA3255 class D chip. Its PurePath Ultra-HD technology combines integrated feedback with high-speed gate-driver error correction for high power with low distortion. FiiO adds a post-filter feedback (PFFB) loop, which lowers output noise and output impedance (under 0.2Ω), improves THD+N and intermodulation distortion, keeps the frequency response steady whatever the speaker load, and suppresses distortion from the output LC filter. The result: THD+N below 0.0025%, a signal-to-noise ratio of up to 111dB and a frequency response of 5Hz–40kHz.

Audiophile-grade parts inside

A six-layer, immersion-gold, thick-copper circuit board and fully shielded power inductors keep the signal stable and the power delivery efficient. FiiO tuned the sound with a mix of capacitors chosen for their character: German WIMA, and Japanese Nichicon and ELNA.

Every source, one box

Connect a CD player or a turntable with a phono stage to the RCA line input, a CD player or transport to the coaxial input (up to 192kHz/24-bit), and a computer to the USB-C input, which works as a USB DAC up to 96kHz/24-bit and has a driver-free mode. Your phone can stream over Bluetooth 6.0 with LDAC at up to 990kbps, about three times the data of standard Bluetooth.

The subwoofer output adds a powered subwoofer for a 2.1 system, and the pre output lets the LEVEL 1 work as a preamplifier for a separate power amplifier. Speakers connect to 4mm banana sockets, which also take bare wire.

Hands-on controls and coloured lights

Dedicated treble and bass knobs on the front (−10 to +10) let you balance the sound for your music or speakers with a simple turn. Press the volume knob to change input, and its RGB light shows which one you’re on: green for line in, orange for USB, yellow for coaxial. On Bluetooth it shows the codec, blue for SBC and white for LDAC, and the light can be turned off. A retro slide switch handles power.

For the digital inputs (Bluetooth, coaxial and USB), the FiiO Control app adds a parametric EQ and presets, and firmware updates.

Metal meets wood

The aluminium alloy chassis has real wood side panels: walnut on the black version and maple on the silver. With its toggle switch and precision-machined knobs, it blends industrial precision with retro warmth.

Good to know

• The LEVEL 1 is for passive speakers, which aren’t included. For 300W per channel you need a separate 53V supply of 600W or more; the included adapter gives 120W per channel.
• The line input is line level: a turntable needs a built-in or separate phono stage.
• FiiO’s specification lists LDAC and SBC for Bluetooth; its product page also mentions AAC.
• Cables for your sources: FiiO LINK-RCA1 (analogue) and LINK-RCA2 (coaxial).
• In the box: LEVEL 1, 48V/5A power adapter, AC power cord, quick start guide and warranty card.
