Simplified Audio, Re-engineered

We designed the Element Line for precision fit and function. EL DAC II+ furthers the exceptional performance of its predecessor with relay muting, an XMOS based UAC2 engine with PCM and DSD support, transformer isolated coaxial input, and a higher performance optical input. Optionally choose Balanced Outputs for the flexibility of connecting to any amplifier, or choose a BT5 Module for wireless streaming. Stack with EL Amp II+ or EL Amp II+ Balanced for single button switching between headphones and speakers.

“

EL DAC II+ is unexceptionally well-executed DAC. I have no doubt that you (or I) could spend far more but I'm not sure you can get anything better anywhere near this price.

Features

MEMS Oscillator

EL DAC II+'s USB engine is clocked by an SiTime MEMS oscillator, delivering pristine jitter.

Relay Muting

Microprocessor controlled relays are standard in EL DAC II+ so that power up and input mode changes are free of audible transients.

USB Audio Class 2

EL DAC 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.

Externally Powered

EL DAC II+ is powered by a perfected supply network, with an external AC transformer and 14 regulators that ensure consistent rail voltage and super low ripple. Never be bothered by USB hubs or OS power difficulties again.

Light Ring

Enjoy the presence of your EL DAC II+ with front and center mode selection via a touch-sensitive light ring.

Differential Summing Output

Differential output of an ESS Sabre DAC is paired with our unique, DC coupled, precision tuned I/V converter with three stages per channel, or six NJM opamps in total. Optional Balanced TRS Outputs and single-ended RCA Outputs provide flexibility of connecting to any amplifier.

Transformer Isolated S/PDIF

Coaxial S/PDIF input is isolated using a Pulse transformer to minimize the possibility of ground loop noise.

ASIO and DSD Support

EL DAC II+ provides an ASIO endpoint and automatic handling of PCM and DSD playback. Live sampling rate and status mode information is available in the XMOS control panel.

Upgradeable Firmware

Our custom XMOS based firmware configures and manages EL DAC II+'s USB input and DAC, with DFU support for possible future feature additions.

Optional Bluetooth 5

An optional Bluetooth 5.1 module feeds the received digital audio signal directly to the DAC via S/PDIF, relying on ESS's patented jitter recovery to deliver maximum performance from the wireless transmission.

Customer Reviews

Aug 19, 2024

I’ve spent quite a bit of time this weekend listening to my new EL Dac 2+.It’s paired with a Yamaha cds 303 which I thought sounded pretty good with the internal dac. I was mistaken about that. I never dreamed what I was missing. This relatively inexpensive (379.00) cd player now sounds like something much more expensive. My cd’s have never sounded so good. I’m guessing you probably hear this frequently. Thank you for making such a wonderful, quality product! I’m glad my search for my first dac led me to JDS. Thanks again
