Crutchfield Customer Review (What's this?)

This is my first dedicated headphone amp, the standard previously just plugging headphones into whatever portable device I have. Ordered this alongside the HP-3 as I like their style (and after paying for the HP-3 may as well go all the way for the full experience right? :)). This amp actually arrived before the headphones so I took the time to set it up and and use it with my previously purchased x20i's. This amp is very well built, it feels very solid, switches feel amazing, volume knob buttery smooth, headphone plug even feels particularly satisfying plugging into the unbalanced port. Tried out the digital coaxial mode through an iBasso DX50 DAP along with also setting up the USB on a Surface Book. Both methods work extremely well. On the PC I ended up using foobar as the music player with the wasapi plugin which would bitstream DSD along with keeping the PCM audio as clean as possible. It's plug and play so didn't need to install anything to select it for use. I wasn't really sure what to expect using the x20i headphones with the amp, the only other device I really ever used those on is the iBasso DX50, which I figured sounded pretty perfect. With as little room for improvement as I thought there was, there is indeed room for improvement. Plugging those little IEMs into this amp results in a noticeably cleaner sound, headphones sounded very clean. Ended up spending more time with this than I thought I would as everything just sounded so pleasin

Product Research


Overview: The Klipsch Heritage Headphone Amplifier features audiophile-quality internal components with a beautiful aluminum and walnut exterior. The headphone amp has a sleek black extruded aluminum chassis, sandwiched by two pieces of MDF with genuine walnut veneer. The front panel switches, knobs, and controls are made of anodized aluminum, and are weighted for a quality feel. Front and rear panel connections are gold-plated for maximum signal transfer. The Klipsch Heritage Headphone Amplifier comes with an AC power adapter with plug adapters for the US, UK, the EU, and Australia, plus an A-B USB cable.

D/A Converter: The Heritage Headphone Amp is equipped with an audiophile-grade ES90128K2M ESS Sabre32 Reference digital-to-analog converter (DAC). This high-resolution DAC is capable of sample rates up to 192kHz/24-bit, making it the best choice for processing your digital audio sources. Other sample rates supported by the DAC include 44.1kHz, 48kHz, 88.2kHz, 96kHz, and 176.4kHz; 16-bit and 24-bit. DSD support includes 2.8MHz, 5.6MHz, and 11.2MHz files. The LEDs on the front panel will indicate the sample rate being processed for digital sources, glowing white for PCM sources and blue for DSD files.

USB Interface: The headphone amplifier uses the XMOS Asynchronous USB Audio interface for transferring audio from USB sources. This interface lets the amplifier lock the audio stream to its internal clock for pristine, jitter-free audio. USB driver software for the headphone amplifier is provided on the Klipsch website. With an optional Apple Lightning-to-USB Camera Adapter, or a USB On-the-Go adapter (USB OTG), you can connect your iOS or Android device directly to the headphone amplifier and bypass the device's built-in DAC.

Dual Amplifiers: The unit has dual Class AB TPA6120A2 amplifiers from Texas Instruments to output a strong, clean signal to your headphones. Having dual amplifiers minimizes crosstalk between channels, and increases the total power output to the headphones. The TPA6120A2 amplifiers have a very high signal-to-noise ratio to provide a super quiet signal. The headphone amplifier output varies depending upon the impedance of the connected headphones:

Connection Power Output
Balanced XLR-4 Unbalanced 1/4"
16Ω 525mW 810mW
32Ω 1440mW 940mW
150Ω 1050mW 270mW
300Ω 540mW 135mW
600Ω 270mw 68mW

Inputs and Outputs: The Heritage Headphone Amplifier features a variety of inputs, both digital and analog. On the rear panel are USB (Type B), Optical (TosLink), and Coaxial digital inputs, as well as stereo RCA analog inputs. Front panel outputs include a balanced XLR-4 output and an unbalanced 1/4" output. The stereo RCA analog output on the rear panel can be set to fixed or variable. When set to variable, you can adjust the gain control using the volume knob on the front panel.

Controls: The headphone amp has a rotary input select dial on the front panel that lets you choose the USB, Optical, Coax, or Line input. The 2-way Output Switch lets you toggle between the headphone output (XLR-4 or 1/4") and the line output (stereo RCA). The headphone output is muted when the switch is set to Line output. The Gain toggle switch lets you choose between Lo-Z (0 gain) and Hi-Z (+10dB gain) if needed for "hard-to-drive" headphones. The large rotary Power/Volume Control lets you set the headphone volume and power the headphone amplifier on or off. (The amplifier is turned off when the rotary control is turned all the way counter-clockwise.) On the rear panel, a 2-way slide switch allows you to set the Line Output to Fixed or Variable. The front panel volume control is disabled when set to a Fixed output.
