LUXURY&PRECISION (hereafter LP) delivers products designed to eliminate the struggles audiophiles often face—whether with high-sensitivity IEMs, low-efficiency headphones, or the wide variety of driver types.
With unmatched driving power in a truly portable form, the W2 Ultra USB DAC/Amp is built to handle even flagship-level headphones with ease. Backed by LP's cutting-edge engineering, it delivers powerful output while providing refined tuning options to meet various listening preferences.

Why "Ultra"?

Achieving sufficient driving power for flagship headphones is no trivial feat. The "Ultra" in W2 Ultra is not just about momentary peak specs on a datasheet—it’s about sustained, stable, and true driving capability. Six major upgrades from the original W2 make this possible:

◆ Optimized circuit layout and power supply design
◆ High-power amplifier supporting sustained 800mW output
◆ SDF tuning specifically crafted for high-end models like HD800 and Utopia
◆ Dual-stage amp voltage switching (±4.5V / ±6V) for both durability and output strength
◆ Custom large heat sink + carbon fiber rear for efficient thermal control
◆ Redesigned user interface with a new color & aesthetic

Dual Signature Tuning by LP

Unlike standard products that rely on EQ or digital filters to tailor a fixed sound, LP employs both waveform analysis and auditory evaluation to develop two distinct sound signatures.
You can easily switch between them:

TUNE01: Offers a wider, airier presentation, ideal for vocals and human voice-centric tracks.
TUNE02: Provides precision and control, ideal for symphonic works or complex arrangements.

High Output, Low Distortion, Low Power Consumption

The W2 Ultra outputs up to 890mW at 32Ω, while maintaining low noise floor and excellent time-domain accuracy. Even with ±6V mode activated, power consumption was measured at only around 4% battery drain per hour on a smartphone.
Thanks to LP's advanced copper shielding, thermal treatment methods, and power-efficient circuit design, high output no longer means high power drain. The result is a reference-grade sound—pure, clean, and free of harshness.

Expansive Dynamic Range

With an extremely low THD+N of approximately -92dB, the W2 Ultra delivers crystal-clear and immersive sound with delicate nuance.

Refined “Classical” Sound Signature

The W2 Ultra refines the classic LP tuning philosophy using dual CS43131 DAC chips.
It offers a zero-noise, ultra-clean sound even when paired with sensitive low-impedance IEMs or under high output loads. Precision engineering eliminates unwanted noise while enabling rich, expressive playback.
A variety of preset EQs and IEM-focused tuning options are available to suit all preferences.

Precision Meets Purpose – LP’s Philosophy

LP's engineers researched the relationship between amp voltage and driver sensitivity. The result:

• PAV Switching Mode, which optimizes voltage for IEMs and full-size headphones.

• SDF Switching Mode, which adjusts the output style based on the sonic characteristics of specific IEM/headphone models.
  When SDF + High Gain are combined, even ultra-demanding flagship headphones can be fully driven.

SDF-Optimized Models Include:

SONY: IER-M9, IER-Z1R
SENNHEISER: IE600, IE900, IE800S, HD800
beyerdynamic: Xelento Remote
SHURE: SE846
AKG: N5005
FOCAL: Utopia
Oriolus: Traillii Ti

Custom Large Heat Sink for Continuous Performance

Sustained high-power output requires robust thermal management.
The W2 Ultra features a custom-designed heat sink that efficiently dissipates heat from the DAC and amp chips. The entire layout—including circuit, wiring, power, capacitors, and amp modules—was redesigned to ensure long-term, stable output beyond peak measurements.

Supreme Portability

Weighing just 26g, the W2 Ultra achieves ultimate compactness without compromise.
A detachable Type-C cable allows flexibility and compatibility with LP’s upgrade cables and other high-quality options in varying lengths and materials.

Enhanced User Interface

Only a single ALPS rotary knob is present—offering precise volume control with tactile feedback and stylish simplicity.

Adaptable to All Use Cases

Beyond music, the W2 Ultra supports EQs optimized for movies and gaming.
Switchable UAC1.0/UAC2.0 modes ensure compatibility with home gaming consoles and more, delivering fast, clean audio performance across all media.

Versatile Outputs from a Compact Device

3.5mm: PO and SPDIF
4.4mm: Balanced PO
The professional-grade LP SPDIF OUT ensures stable and high-quality digital output.
