Heritage Audio OHM Headphone Matching Amp

Whether you want to use its balanced input, gold-plated RCA input or even its pro quality Bluetooth receiver with Burr Brown DAC, the O.H.M Amp offers three independently selectable top quality input sources for your headphones to shine. Once the input source is selected, the O.H.M Amp’s impedance switch allows you to match the signal’s output impedance to your headphone’s particular impedance to ensure you get the most out of your them, whether they be a set of the cheapest low impedance earbuds around or one of the highest quality, audiophile-grade models.

The O.H.M Amp provides two different ways to connect your headphones, independent 6.35 and 3.5 mm (1/4” and 1/8”) built-in jack connections on the front of the O.H.M Amp are provided so you can finally forget about noisy adapters…seriously, why hasn’t anyone thought of that before?

Its discrete diamond buffers, taken from our highly acclaimed R.A.M System 2000 and 5000 models, and Burr Brown Op Amps for extreme fidelity and ultra low noise, ensure that this mighty headphone amp will deliver an audiophile-grade response for whatever your headphones are.
