DMP-Z1 Digital Music Player Signature Series
High Resolution Audio
Experience digital music to the fullest with High-Resolution Audio. By capturing music at a higher rate than CD, increasing both audio samples per second and the bitrate accuracy of each sample, High-Resolution Audio offers an uncompromised rendition of an artist’s music. Savor every breath and subtle movement for a truly emotional experience.
4.4 mm (0.17″) balanced connection and 3.5 mm (0.14″) standard headphone jack engineered with KIMBER KABLE®
Clear stereo separation and soundstaging is delivered by a 4.4 mm balanced headphone jack, which is compatible with a broad range of premium headphones. The internal wiring for both the 4.4 mm unbalanced and the 3.5 mm standard jacks uses a thick KIMBER KABLE® for signal integrity.
Gold-plated volume control
Enjoy stereo channel precision right to the headphone output with the custom-crafted passive-balanced volume potentiometer. Copper and gold-plated brass ensures absolute sonic purity across all dynamic levels.
Power pure audio everywhere with built-in battery
Five battery cells drive both digital and analog amplification circuits independently for enhanced dynamics and reduced internal electromagnetic interference. By isolating the power delivery from conventional AC power supplies, you enjoy both a more open treble response and tighter bass delivery, without the harshness transmitted through AC line noise.
High-quality analog amplifier
By incorporating an audiophile-grade, high-power headphone amplifier, the DMP-Z1 realizes 1,500 mW (16 Ω)1 to drive even the most demanding headphones.
Dual DAC stereo architecture
Exceptional stereo imaging and an enhanced dynamic range is delivered through two independent AK4497EQ mono Digital-Analog Convertors (DACs), especially when matched with balanced headphone listening. An exceptionally low noise floor and native support for ultra-high-resolution audio formats ensures absolutely pristine analog audio translation.
Rigid frame structure
To ensure minimal resonance and vibration are transmitted between the isolated boards, all circuit boards of the DMP-Z1 are mounted on a solid, frame-based chassis. This lessens external electrical or seismic interference so that each circuit can achieve optimal performance.
Gold-plated oxygen-free copper (OFC) plate
An OFC plate on the circuit board with gold plating (minimum purity 99.96) reduces contact resistance, giving a clearer audio quality. Gold plating also prevents oxidization and improves ground stability too.
New EDLC capacitor for improved battery performance
Five electric double-layer capacitors (EDLC) with large capacity and low ESR (Equivalent Series Resistance) supply power from the batteries of the DMP-Z1. This means no sudden falls in voltage, and power is stably supplied to the DAC and amplifier.
Newly-developed FT CAP (High polymer capacitor) for voltage stability
The DMP-Z1 features newly-developed FT CAP high polymer capacitors in the power supplies for the DAC and amplifier, which inhibits voltage spikes that could cause subtle audio distortions. The result is clear, transparent melodic lines and tight bass line control, regardless of your choice of music.
Enhanced power supply for the audio circuit
Engineered specifically for portable performance, the power circuit dedicated to the analog audio board makes an ideal pairing for the DC battery-power of the DMP-Z1. An extremely low-noise voltage regulator and DC/DC converter ensure pristine power is delivered to the amp, with enough headroom to comfortably drive even the highest impedance headphones with maximum dynamics and a minimal noise floor.
Premium, audio-grade lead-free solder containing gold
The all-important headphone outputs and other outputs of the DMP-Z1 feature newly developed lead-free solder with the addition of gold to enhance the signal flow. The exceptional conductivity of gold ensures the absolute minimum signal loss possible, for full dynamic range delivery.
Shielded OFC cables for improved channel separation
OFC (Oxygen-free cable) shielded cables are designed for lower resistance and a superior signal-to-noise ratio. Separate cables transmit the balanced audio signals for right and left channels independently, to prevent cross-talk and interference and ensure a perfectly presented soundstage.
Optimized circuit board layout
By isolating the power supply, digital circuitry, and analog amplification in the circuit design, the DMP-Z1 has dramatically lower electronic interference, reduced noise and improved overall sound clarity.
Super low phase noise crystal oscillator
Large volumes of data are processed without losing sound quality through two newly-developed crystal oscillators, which keep noise to a minimum.
Give all PCM music the DSD treatment with DSD Remastering Engine
PCM (Pulse Code Modulation) audio is resampled into a 5.6 MHz DSD (Direct Stream Digital) ultra-high-frequency 1-bit audio stream. The single-bit stream delivered to the DAC has a character far closer to that of analog-so your music is delivered exactly as the artist intended.
Give every track the sound of vinyl with Vinyl Processor
Get lost again in the richness of the melodies and dynamics of your favorite albums by giving back the character of vinyl to your digital tracks. Subtle reproduction of the low-frequency resonance, tone-arm resistance, and surface noise deliver an authentic listening experience.
New DSEE HX™ analyzes song type by AI
Audio upscaling is improved even further by our new DSEE HX™ processor which intelligently recognizes instrumentation and musical genres. Realism and liveliness of different instruments, including the human voice, are inherently characterized by high-frequency harmonics. By identifying instruments, and the relative energy of the audio, our enhanced DSEE HX™ can accurately rebuild audio lost during digital compression for a full fidelity experience, even with compressed audio formats.
