Heritage Audio OHM Impedance-Matching Headphone Amplifier SKU# OHM

Heritage Audio has changed the game of headphone amplification with its revolutionary O.H.M. Amp, the first of its kind to offer a combination of impedance-matching amplification, three independently selectable input sources, and both 6.35mm and 3.5mm built-in jack connections to ensure you receive the highest level of sonic performance from your headphones. Whether you rock top-of-the-line cans or budget-friendly buds, this amp houses the necessary components for dynamic, crystal clear audio, including the discrete diamond buffers commonly found on Heritage Audio’s high-end R.A.M. System models, Burr-Brown op-amps for ultra-low distortion and high-fidelity audio performance, and the coveted Alps “Blue Velvet” potentiometer that gives all audiophiles full control over their output levels. As if the O.H.M. Amp wasn’t already bursting with top-notch sonic aptitude, Heritage Audio also included a thru output that allows for chaining options or Bluetooth receiver capability and a 30-volt power supply to provide dynamic range, adequate signal-to-noise ratio, and strong power delivery with low distortion at any impedance. A true trailblazer in the audio sphere, Heritage Audio’s O.H.M. Amp will push your headphones to their optimal performance level and deliver an exceptional listening experience.

Heritage Audio’s O.H.M. Amp is built around three foundational components to support your headphones in achieving peak sonic production: First, the O.H.M. Amp offers three top-quality, independent input sources — a balanced input, a gold-plated unbalanced RCA input, and a Bluetooth receiver with Burr-Brown DAC. It then allows you to dial in the impedance level that best matches your particular headphones, with a range beginning at “low” impedance output and capping at 600 ohms. Lastly, the O.H.M. Amp includes two independent 6.35mm and 3.5mm jack connections for your headphones, meaning that you can ditch those noisy, staticky third-party adapters in favor of direct audio bliss.

At the heart of the O.H.M Amp are discrete diamond buffers, borrowed from the acclaimed R.A.M System 2000 and 5000 models, and Burr Brown Op Amps, delivering extreme fidelity, ultra-low noise, and audiophile-grade performance. Control your output with precision using the highly coveted Alps Blue Velvet potentiometer, a standout feature in high-end audio equipment.

Need flexibility? The O.H.M Amp can double as a premium Bluetooth receiver or link multiple units together via its built-in pass-through outputs. The custom-designed 30V external power supply ensures exceptional dynamic range, signal-to-noise ratio, and ultra-low harmonic distortion, for any audio application.

Whether on a studio microphone stand or elegantly placed on your desk with its rubber feet, the O.H.M Amp is designed for convenience and style. Unlock the full potential of your headphones with the O.H.M Amp—a true game-changer for audiophiles and professionals alike.
