Klipsch® Heritage Headphone Amplifier-1064316

Driven at the core by a high-resolution ES90128K2M ESS Sabre32 Reference digital-to-analog (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.

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.

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.

The Heritage Headphone Amplifier is intended to work as a digital analog processor for USB audio, optical, and coaxial inputs. Beyond its 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.

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.

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.

Encased in formed aluminum with genuine walnut veneer, the Heritage Headphone Amplifier exudes quality before plugging in your headphones. 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 a vintage feel.

McIntosh® 2 Channel Headphone Amplifier-MHA150

McIntosh® 2 Channel Headphone Amplifier with 50 watts per channel and crossfeed director function

The MHA200 Vacuum Tube Headphone Amplifier is designed for discerning headphone enthusiasts who demand the most from their headphones. Its versatile set of connectivity options, including balanced inputs and outputs, allows for nearly all headphone types 

McIntosh® 2 Channel Headphone Amplifier-MHA200

Compact footprint: just 6-1/8" (15.6cm) x 9-1/8" (23.2cm)

Balanced stereo or dedicated Left & Right outputs

A pair of 12AT7 and 12BH7A dual triode vacuum tubes power the compact MHA200. The 12AT7 vacuum tubes amplify the incoming audio signal while the 12BH7A tubes provide the power to drive the output to your headphones with low distortion. The MHA200 uses a pair of our Unity Coupled Circuit output transformers to deliver pristine audio to your ears. Our Unity Coupled Circuit is the same technology McIntosh was founded on in 1949 and is still used in our vaunted full-size home audio vacuum tube amplifiers such as the timeless MC275 and the more recent MC1502. Indeed, the MHA200 shares many physical design traits with the aforementioned vacuum tube amplifiers.

A wide assortment of connectivity options come on the MHA200. For attaching your headphones, there are 3 options: a pair of 3-pin balanced XLR connectors for dedicated Left and Right balanced output; a 4-pin balanced XLR connector for balanced stereo output; and a 1/4" stereo headphone jack.

For connecting the MHA200 to your home music system's source components, it has 1 set each of both balanced and unbalanced inputs. Thanks to the MHA200's small size of just 6-1/8" (15.6cm) wide x 9-1/8" (23.2cm) deep and its balanced inputs, it can be placed close to your listening position for ease use, with long balanced audio cables connecting it to your audio system without fear of signal loss.

The MHA200 takes advantage of unique McIntosh technologies to create the best possible personal listening experience. The Unity Coupled Circuit transformers have been adapted to produce 4 headphone impedance ranges of 32 – 100, 100 – 250, 250 – 600, and 600 – 1,000 Ohms at 500mW so that virtually every headphone can receive legendary McIntosh sound quality and performance.

We custom designed and manufactured the output transformers to match the tube amplifier section to the headphone output section in order to ensure maximum power transfer for various headphone loads. Instead of having to adapt to the impedance of the headphones with voltage gain in the input stage, the Unity Coupled Circuit output transformers' secondary windings ensure the full power of the MHA200 is available regardless of the impedance of your headphones. A custom, high-performance, and highly efficient toroidal power transformer with low mechanical hum and a low magnetic field, which helps reduce electrical noise, provides clean power to the amplifier.

You can select the best impedance range for your headphones via the LOAD knob. The VOLUME knob allows the MHA200 to be connected directly to music sources that only have a fixed volume output without needing a preamplifier for volume control. Conversely, if you're using a component with variable volume output, then the VOLUME knob should be set to the center Unity Gain point and the volume controlled by the variable output component.

The MHA200 features a custom formed stainless steel chassis with a polished mirror finish that will accentuate the glow of the vacuum tubes, making it a statement piece to display in your home and to use with pride. A vintage die cast aluminum McIntosh name badge adorns the side of the MHA200. A Power Control input and output allows the MHA200 to turn on and off with other connected McIntosh components, such as preamplifiers, CD players, turntables, or media steamers. A protective vacuum tube cover is included.

The MHA200 Vacuum Tube Headphone Amplifier is designed for discerning headphone enthusiasts who demand the most from their headphones. Its versatile set of connectivity options, including balanced inputs and outputs, allows for nearly all headphone types to be connected to enjoy an extraordinary personal listening experience.
