FiiO DM15 R2R Black Hi-Fi CD Player

Portable CD Player with True R2R DAC Architecture

The FiiO DM15 R2R is a portable CD player built around a fully differential 24-bit R2R resistor-ladder DAC — the same conversion topology used in the earliest CD players, now revived for warm, organic CD sound. Inside the chassis, 192 precision resistors feed an FPGA stage and a proprietary MCU controller. The DM15 R2R is the right choice for audiophiles who want authentic CD playback without giving up modern connectivity or headphone-driving power.

What Sets This CD Player Apart

Unlike most portable CD players that rely on off-the-shelf delta-sigma chips, this model uses FiiO's self-developed fully differential R2R architecture — a rare, labour-intensive design that gives CDs a smoother, analogue-style presentation. A patented Desktop Mode bypasses the battery when plugged into USB power, preserving cell health for years. The transparent tempered-glass lid reveals the spinning disc, while a self-rebounding three-ball spring hub centres each CD.

R2R DAC and Multi-Source Digital Hub

The DAC section pairs a fully differential 24-bit R2R resistor array with an FPGA platform and proprietary MCU controller, producing warm playback with THD+N below 0.030% and SNR of at least 112 dB (A-weighted). The same architecture processes USB audio up to 384 kHz/32-bit PCM and DSD256 from external sources.

• DAC: Fully differential 24-bit R2R resistor array (192 resistors, 48 per channel) — analogue-style warmth with low distortion
• USB DAC Support: Up to 384 kHz/32-bit PCM and DSD256 — high-resolution playback from external sources
• USB Ripping — archive discs to WAV files on external storage while the disc keeps spinning

Headphone Drive and Output Power

Both 3.5 mm single-ended and 4.4 mm balanced outputs run on dedicated SGM8262 amplification stages. In Desktop Mode the balanced port delivers up to 1150 mW + 1150 mW into 32 Ω for full-size over-ear headphones, while the single-ended port produces 315 mW + 315 mW for sensitive IEMs. Line-out options include a 3.5 mm LO/COAX/OPT 3-in-1 socket and a 4.4 mm balanced line-out.

• Balanced Output (Desktop Mode): 1150 mW + 1150 mW at 32 Ω — drives demanding over-ear headphones
• Single-Ended Output: 315 mW + 315 mW at 32 Ω — clean power for IEMs and portable headphones
• Digital Outputs: Coaxial up to 192 kHz/24-bit, optical up to 96 kHz/24-bit — feed external DACs and amplifiers

Bluetooth, Battery Life and Construction

Wireless streaming runs on a Qualcomm QCC3095 Bluetooth 5.4 chipset supporting SBC, aptX, aptX Adaptive and aptX HD, sending CDs to wireless headphones or speakers without cables. A 4700 mAh pure cobalt high-voltage lithium battery delivers roughly seven hours of playback and recharges in about two hours via PD3.0.

• Bluetooth: Qualcomm QCC3095, Bluetooth 5.4 with aptX HD, aptX Adaptive, aptX, SBC — high-resolution wireless streaming
• Battery: 4700 mAh high-voltage lithium, ~7 hours playback, ~2 hours PD3.0 charging — real portability without daily recharging
• Build: Aluminium-alloy frame, tempered-glass lid, 144 × 137 × 25.5 mm, 471.5 g — solid in the hand, slimmed by 2 mm versus the DM13

Who Should Consider This Player

The FiiO DM15 R2R is the right choice for CD collectors and audiophiles who want a single device that handles discs, USB audio and wireless streaming without compromise. It suits listeners with a vintage CD library who appreciate the warmer, more organic character of R2R conversion, plus headphone enthusiasts who need desktop-grade power from a transportable chassis. Desktop users can pair it with an external amplifier or active speakers via balanced line-out, coaxial or optical outputs, while portable listeners stream via Bluetooth 5.4 on the move.

The DM15 R2R Successor Story

This model builds directly on feedback gathered from the earlier FiiO DM13 portable CD player, refining both sound quality and everyday usability. Compared to its predecessor, the chassis is 2 mm slimmer while delivering higher output power, a true R2R DAC architecture, USB DAC, Bluetooth transmission, and CD-to-WAV ripping. FiiO's R2R programme now spans dedicated DAPs, desktop DACs and this CD player, bringing the resistor-ladder topology — once standard in first-generation CD players — back into a modern portable.
