Wether 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 selector 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 also provides two different ways to connect your headphones, independent 6.35 and 3.5 mm 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.

Want full control over the output level? We have spared no expenses when designing the O.H.M Amp. The highly sought-after audiophile-grade Alps “Blue Velvet” output level potentiometer is the icing on the cake of this beautiful headphone amp. You can even chain multiple units together using the built-in pass-through outputs or use it as a premium Bluetooth receiver.

And to make things even more precise, an external high voltage, low-noise 30V power supply has been specifically designed for incredible power delivery at any impedance, ensuring an adequate dynamic range, signal to noise ratio and an ultra low harmonic distortion performance.

Finally, no matter what you`re going to use the O.H.M Amp for, its convenient rubber feet will allow it to be used as an elegant tabletop device or the drilled 5/8¨ hole on its bottom will allow you to mount it on any microphone stand in the studio.
