JDS Labs EL DAC

JDS Labs have designed the Element Line for precision fit and function. EL DAC delivers performance far beyond Objective criteria, with full USB Audio Class 2 support, transformer isolated coaxial input, and optical input. Stack with EL Amp for single button switching between headphones and speakers.

Complete connectivity.

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

4-Layer PCB
All JDS Labs DACs are built on 4-layer printed circuit boards to achieve proper USB characteristic impedance of 90 ohms.

USB Audio Class 2
EL DAC supports up to 32/384kHz audio using a dedicated 45/49MHz clock pair. While we claim no measurable superiority of high sampling rates, UAC2 and ASIO support satisfy your pursuit of bit-perfect listening.

Externally Powered
EL DAC is powered by a perfected supply network, with an external AC transformer and 12 linear 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 with front and centre mode selection via the touch-sensitive light ring.

Differential Summing Output
The differential output of the AK4490EQ DAC is summed by an OPA2227, with DC coupling throughout. Drive any load you wish, satisfactorily.
