Heritage Audio Unveils the O.H.M Amp

A Groundbreaking Impedance-Matching Headphone Amplifier for Studios and Audiophiles

Heritage Audio has introduced the O.H.M Amp, the world’s first impedance-matching headphone amplifier specifically designed for both studio professionals and audiophiles. This innovative device ensures that every pair of headphones, from budget-friendly models to high-end audiophile-grade cans, can perform at their absolute best.

Versatile Connectivity and Advanced Features

The O.H.M Amp boasts a rear panel equipped with three distinct input options, catering to a wide range of audio setups. It features two Amphenol XLR 1/4” combo balanced inputs (IN BAL), a pair of gold-plated unbalanced RCA inputs (IN UNBAL), and a built-in Bluetooth receiver supporting APT-X®, APT-X LL®, APT-X HD®, AAC, and SBC codecs. Paired with a Burr Brown digital-to-analog converter (DAC), the O.H.M Amp delivers exceptional audio clarity and fidelity.

User-Friendly Operation

Selecting the ideal input source is effortless, thanks to the front panel’s intuitive Bluetooth, BAL, and UNB buttons. The IMPEDANCE selector allows users to match the output signal’s impedance to their headphones’ specifications, ensuring optimal performance regardless of the headphone’s impedance rating. Whether you’re using affordable low-impedance headphones or premium high-impedance models, the O.H.M Amp maximizes their potential.

Premium Audio Performance

The front panel offers two headphone output options: a 6.35mm (1/4”) jack and a 3.5mm mini-jack. At the heart of the O.H.M Amp lies Heritage Audio’s renowned R.A.M System 2000 and R.A.M System 5000 desktop monitor systems, featuring independent diamond buffers and Burr Brown op-amps. This combination guarantees exceptional audio fidelity and ultra-low noise levels, making it a standout choice for critical listening.

Precision Control and Expandability

The O.H.M Amp is equipped with an Alps “Blue Velvet” output LEVEL potentiometer, giving users complete control over the output level. Additionally, the rear panel’s THRU output allows for daisy-chaining multiple O.H.M Amps or using the device as a high-end Bluetooth receiver. To ensure robust power delivery, the amplifier is powered by an external high-voltage, low-noise 30V power supply, delivering outstanding dynamic range, signal-to-noise ratio, and minimal harmonic distortion across all impedance levels.

Pricing and Availability

The O.H.M Amp is priced at €549 or $499, making it an accessible yet premium option for audio enthusiasts and professionals alike. With its cutting-edge technology and meticulous design, the O.H.M Amp sets a new standard for headphone amplification, offering unparalleled versatility and performance.
