VINTAGE NOSTALGIA
Encased in formed aluminum with genuine walnut veneer, the Heritage Headphone
Amplifier exudes quality before ever being plugged in. All switches, knobs, and controls
are weighted and anodized aluminum for great feel and tactile response. All analog
switches operate through relays for the cleanest signal while maintaining vintage feel.
AUDIOPHILE DIGITAL TO ANALOG CONVERTER
Driven at the core by a high-resolution ES90128K2M ESS Sabre32 Reference digital-toanalog (DAC) converter capable of 192kHz/24-bit sample rates, the Heritage Headphone
Amplifier is the ideal 2-channel audiophile-grade DAC. Featuring ESS 32-bit HyperStream®
DAC architecture and Time Domain Jitter Eliminator, the amplifier delivers a clear sound
and minimal distortion. Built for the most discerning ears, the Heritage Headphone
Amplifier doubles as an ideal processor of any digital source, whether the output is a pair
of headphones or RCA line-out.
ASYNCHRONOUS USB INTERFACE
The Heritage Headphone Amplifier uses the XMOS USB audio receiver platform, widely
regarded as one of the best solutions for transferring audio from USB sources. This
allows the amplifier to lock the audio stream to its internal clock, keeping the audio
stream as clean as possible. ASIO support is included for audio software that supports
it. iOS (with Lighting™ to USB Camera Adapter, sold separately) and Android (5.0 Lollipop
and newer) devices can also connect directly to the USB interface for lossless playback
of content, bypassing your device’s digital-to-analog converter.
DUAL AMPLIFIERS FOR BALANCED OUTPUT
Complete with dual Class-AB TI TPA6120A2 amplifiers, the signal path minimizes
crosstalk while increasing total system output. Built to have the best signal to noise
ratio possible, the chosen amplifiers had to be as quiet as the reference DAC. Plug
in any headphone with an XLR-4 balanced cable (not included) and you have a true
audiophile solution. Flip the gain switch to “Hi-Z” for a +10 dB boost in output to drive
even the most demanding headphones.
VERSATILE INPUTS AND OUTPUTS
The Heritage Headphone Amplifier is intended to work as a digital analog processor
for USB audio, optical, and coaxial inputs. Beyond it’s primary use as a balanced
headphone amplifier, it also works as a DAC for powered speakers, making it the ideal
desktop companion. Toggle the output switch to “Line” and the amplifier will mute
the headphone output and enable the line-out on the back of the amplifier. Flip the
switch on the back of the unit from “Fixed” to “Variable” and you now have gain control
through the volume knob on the front.
LOW DISTORTION
The Heritage Headphone Amplifier is designed to maintain the lowest distortion in
its class. To realize the full performance of the Sabre DAC, the signal path uses relays
and analog gain control. We coupled those elements with a highly customized circuit
board layout and reference components. This amplifier will enhance the quality of any
headphone or audio system plugged into it.
SAMPLE RATE NOTIFICATION
To ensure that all the settings on your input source are correct, the Heritage
Headphone Amplifier displays the sample rate being processed of digital sources. The
front-panel LEDs will illuminate in white for PCM sources and blue for DSD files.
