Element III MK2

$449.00

  • Covered by our 2-year transferable warranty

Simplified Audio, Re-engineered

We redesigned Element II to maximize your desktop audio experience. Element II packs the performance you expect from JDS Labs into a precision machined aluminum chassis, with an equally impressive 32/384k DAC, and button activated preamp RCA outputs. Enjoy the comfortable knob and seamless transitions between your powered speakers and headphones!

Features

PREAMP OUTPUTS

Element II provides preamp RCA outputs, so that you can control volume of your powered speakers.

OUTPUT SELECTION

The Mode button allows you to toggle between headphones and powered speakers. No need to disconnect cables!

ULTRA HIGH POWER

With +/-15VDC rails and continuous max power of 1.3W, Element II drives all headphones on the market to extroardinary levels, from balanced armatures to planar magnetics.

TOP PERFORMANCE

Element II is our most advanced amp+DAC to date, achieving top performance from its 4-layer, star grounded layout.

DUAL GAIN

Low gain of 1.0x is well suited to driving efficient IEMs, while High gain easily powers demanding full size sets.

RELAY MUTING

Designed for desktop listening, Element II's full relay muting eliminates pops and thumps during startup through both its headphone and preamp outputs.

MEMS OSCILLATOR

Element II's USB DAC is clocked by an SiTime MEMS oscillator with ±10ppm frequency stability, delivering pristine jitter.

USB AUDIO CLASS 2

Element II supports up to 32/384kHz PCM over a custom XMOS XU208 based UAC2 engine. While we claim no measurable superiority of high sampling rates, UAC2 and ASIO support satisfy your pursuit of bitperfect listening.

AC TRANSFORMER

Element II's amplifier and DAC are 100% powered by its external AC transformer, with 12 regulators ensuring consistent rail voltage and super low ripple.
