JDS Labs Element IV

The JDS Labs Element IV is a complete redesign of the company’s flagship amp/DAC, engineered to deliver an effortless and refined listening experience. Built on third-generation XMOS hardware and equipped with a precision optical encoder, the Element IV delivers perfect channel balance right down to the noise floor. Automatic gain adjustment eliminates the need for manual switching, while a sleek, auto-dimming display shows only essential information when users switch between USB and optical inputs or headphone and preamp outputs.

The device also integrates seamlessly with Core™, JDS Labs’ new web app, which allows users to intuitively adjust 12-band parametric EQ and other settings. All adjustments are saved directly to the device, ensuring that profiles and presets are retained across different rooms, PCs, or consoles. Designed and built in the U.S., the Element IV combines precision engineering with ease of use.

Key Features

3.2W Power Output

With tetradeca output buffers delivering over 3200mW per channel, the Element IV provides distortion-free power capable of driving any headphone—from sensitive IEMs to demanding planar magnetics.

Parametric EQ with Core™

The custom DSP engine supports up to 12-band real-time parametric EQ, easily managed via the Core web app. Settings are stored internally—no downloads or drivers required—and remain available wherever the Element IV is used.

Automatic Gain Control

The Element IV eliminates guesswork by automatically switching between low and high gain at the right moment, compensating for the volume level to ensure a smooth transition.

Perfect Channel Balance

Designed for precision, the Element IV maintains audibly perfect channel balance down to -127.5 dBFS, ensuring a precise soundstage and imaging.

Preamp Outputs

The preamp outputs allow for direct volume control of active speakers. Users can switch between headphones and speakers with the press of a button, with independent volume levels and EQ profiles saved for each mode.

Customizable Controls

The tactile volume knob switches between outputs by default but can be completely reconfigured via Core.

OLED Display + Gorilla Glass

A subtle OLED display shows status information only during interaction and then dims to minimize distractions. Protected by tinted Gorilla Glass, it is both durable and stylish.

DC Protection & Safety

The Element IV uses proven analog DC detection, failsafe relay damping, and continuous system monitoring to protect headphones and prevent pops and clicks during startup.

USB Type-C Connectivity

The USB Type-C input supports up to 32-bit/384 kHz PCM, with ASIO and DSD compatibility. Full EQ functionality is available up to 192 kHz, with two-band EQ at higher sample rates.

UAC2 or UAC1 Mode

Users can switch between UAC2 and UAC1 for compatibility with modern PCs, older operating systems, and consoles such as the PS5 and Nintendo Switch.

Precision Optical Encoder

The second-generation discrete optical encoder features a reinforced steel shaft and 50% more fins for faster, smoother button response. With a lifespan of millions of rotations, it offers unmatched durability and tactile feedback.

Robust Power Design

The amplifier and DAC are powered by an isolated external AC transformer, supported by 13 precision regulators. Ultra-low-noise rails and mains isolation ensure stable voltage and an unadulterated signal path.

Hifi.nl Rating: 5 out of 5

"The JDS Labs Element IV is an exceptionally powerful headphone amplifier with an excellent DAC section. Technically and sonically perfect as a companion to your computer and suitable for virtually any pair of headphones. What makes the Element IV truly fascinating is its metal chassis and design, featuring a large volume knob that’s a joy to use. Sonically, it’s exceptionally transparent.

If you enjoy tweaking your sound, the Core software is a godsend. The powerful capabilities for creating your own equalizer presets are top-notch, and the fact that you can also apply a correction for your headphones or IEMs from the headfi community with just one click is fantastic." Read more...
