FiiO DM15 R2R Silver Hi-Fi CD Player

FiiO DM15 R2R — Portable CD Player with a True R2R DAC

The FiiO DM15 R2R brings vintage-era CD listening into the modern age, combining a high-fidelity 24-bit fully differential R2R resistor-ladder DAC with desktop-grade headphone power inside a compact, transportable chassis. Built for audiophiles who want authentic CD playback without being tied to a wall outlet, this player uses 192 precision resistors (48 per channel) to decode every disc with warm, analogue-style musicality. The FiiO DM15 R2R is the right choice for listeners who want a single device that handles CDs, hi-res USB audio, and wireless streaming with equal confidence.

What Sets This Player Apart

Unlike conventional delta-sigma CD players, this unit uses a true resistor-ladder DAC architecture paired with an FPGA platform and a proprietary MCU controller, delivering smoother, more organic playback with low noise and distortion. A patented Desktop Mode bypasses the internal battery when the player is plugged in, preserving long-term battery health for years of stationary listening. The transparent lid with tempered glass reveals the spinning disc, while a self-rebounding steel ball hub makes disc insertion effortless and keeps alignment precise for reliable playback.

True R2R Decoding for a Natural, Musical Sound

The discrete R2R DAC architecture is what gives this CD player its character — a smoother, more organic presentation that many listeners prefer for vocal and acoustic recordings. Combined with the FPGA platform and MCU controller, the digital path stays accurate from disc or USB input all the way to the headphone amplifier.

• DAC Architecture: Fully differential 24-bit R2R resistor array, 192 precision resistors (48 per channel) — the resistor-ladder design gives the player its warm, analogue-style character
• USB DAC Input: Up to 384 kHz/32-bit PCM and DSD256 native — turns a PC, smartphone, or tablet into a hi-res source
• Signal-to-Noise Ratio: ≥112 dB (A-weighted) — quiet passages stay clean and dynamic passages stay bold
• THD+N: <0.030% at 1 kHz / 0 dB into 32 Ω — low distortion across the audible band
• FPGA + MCU digital path — keeps timing and signal routing precise from disc or USB input to the headphone amplifier

Desktop-Grade Output for Demanding Headphones

This player delivers serious current from both single-ended and balanced outputs, with dedicated amplification stages for each. In Desktop Mode the balanced port pushes up to 1150 mW + 1150 mW into 32 Ω, easily driving high-impedance over-ear headphones such as 300 Ω models.

• Balanced Output (Desktop Mode): 1150 mW + 1150 mW at 32 Ω, THD+N < 1% — drives power-hungry planar and dynamic headphones
• Single-Ended Output (Desktop Mode): 315 mW + 315 mW at 32 Ω, THD+N < 1% — clean drive for efficient IEMs and portable headphones
• Headphone Jacks: 3.5 mm single-ended and 4.4 mm balanced — covers both common portable standards
• Line / Digital Outputs: 3.5 mm LO/COAX/OPT (3-in-1) and 4.4 mm balanced LO — feeds external amplifiers, active speakers, or outboard DACs

Real Portability with Bluetooth 5.4 and CD Ripping

The 4700 mAh high-voltage pure cobalt lithium battery powers roughly seven hours of continuous CD playback away from the mains, and PD3.0 fast charging refills it in about two hours. Bluetooth 5.4 with the Qualcomm QCC3095 chipset streams discs wirelessly to headphones or speakers in aptX, aptX Adaptive, aptX HD, or SBC, while the USB-C port doubles as a ripping output for archiving CDs to WAV while listening.

• Battery: 4700 mAh high-voltage pure cobalt lithium, ~7 hours playback — full-length albums on a single charge
• Charging: USB-C, PD2.0 / PD3.0 fast charging, ~2 hours full charge — quick top-ups between sessions
• Bluetooth: 5.4 with Qualcomm QCC3095, aptX / aptX Adaptive / aptX HD / SBC — high-resolution wireless streaming from CD
• CD Ripping: USB CD-to-WAV ripping while listening — digitize a disc library straight to external storage
• ESP Anti-Skip: Electronic Shock Protection switch — steadier playback when carrying the unit between rooms

For Audiophiles, CD Collectors, and Desktop Headphone Listeners

The FiiO DM15 R2R is the right choice for listeners who own a CD library and want a modern, transportable source that does not compromise on sound quality. It suits audiophiles who appreciate the warmer, more organic character of R2R decoding and want a single device that doubles as a hi-res USB DAC for a computer setup. Desktop headphone users benefit from the 1150 mW balanced output and dedicated 4.4 mm jack, while the Bluetooth 5.4 transmitter makes it easy to share music wirelessly with aptX HD headphones or speakers. CD collectors can archive their discs to WAV via the USB ripping function while continuing to listen, and the included infrared remote keeps transport control convenient when the player sits across the room on a hi-fi rack.

FiiO and the Return of the Discman

FiiO built this model as a direct response to user feedback on the earlier DM13 portable CD player, refining the disc mechanism, adding a true R2R DAC stage, and slimming the chassis by 2 mm while dramatically increasing headphone output power. The R2R resistor-ladder approach echoes the architecture used in some of the earliest commercial CD players, bringing that classic decoding philosophy into a modern, multi-source device. The result is a portable CD player that also functions as a USB DAC, Bluetooth transmitter, and digital transport — a flexible hub for anyone rediscovering physical media.
