Simplified Audio, Re-engineered
We redesigned EL Amp to maximize your desktop audio experience. EL Amp II+ packs the performance you expect from JDS Labs into a precision machined aluminum chassis, with higher maximum power, and button activated preamp RCA outputs. Enjoy the comfortable knob and seamless transitions between your powered speakers and headphones! Now available with RCA or Balanced TRS Inputs.
This is your last chance to own the renowned EL Amp II+ at an incredible discount! This isn’t a temporary sale, but a last-buy opportunity. Once they’re gone, they’re gone for good. Please also note that all EL Amp II+'s are marked B-Stock during the Last Buy event.
JDS Labs is one of the very few companies that actually do manage to achieve perfect balance for their products . . .

Features
Preamp Outputs
EL Amp 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!
Plentiful Power
With +/-15VDC rails and continuous clean power, EL Amp II+ drives all headphones on the market to extraordinary levels, from balanced armatures to planar magnetics. Think you need even more? Choose Boosted Power!
Dual Gain
Low gain of 1.0x is well suited to driving efficient IEMs, while High gain easily powers demanding full size sets.
Single-Ended or Balanced Input
We built EL Amp II+ around a rugged 6.35mm headphone output jack, actively discouraging pentaconn connectors. As for inputs, choose the default RCA jacks for use with most DACs, or select Balanced TRS jacks for pairing with audio interfaces and balanced DACs.
Relay Muting
Designed for desktop listening, EL Amp II+'s full relay muting eliminates pops and thumps during startup through both its headphone and preamp outputs.
