Transfer Classes

While sound systems require two channels of output to operate in stereo mode, using a Class-B or Class-AB amplifier creates an inefficient push-pull effect between the currents. Instead of inviting crossover and notch distortion into your set-up, plug into a NuForce HA-200 Headphone Amplifier and discover the joys of dedicated Class-A amplification.

Note: This drop is limited 17 units of the HA-200 in black and 3 units in silver.

A is for Awesome

A Class-A amplifier never shuts off, giving you better performance across high frequencies and more stability in the feedback loop. If you’re worried about energy efficiency or heat transfer from your devices, the HA-200 isn’t for you, but if the highest quality audio is your priority, you’ve come to the right place. The Class-A topography is bolstered by a constant-current bias, which provides stable control over the signal at all times.

Keep Your Balance

With one unit, you can operate in Single-Ended Mode and feed a single 1/4” TRS output. If your headphones crave more power, however, you can use two HA-200s as monoblock amplifiers in Balanced Headphone Mode with the 3-pin XLR output on each unit, bringing quadruple the power to your system. With all that output, you’re getting a fully realized soundstage, extremely clear and pure tones, and an overall fast, authoritative response. While this set-up isn’t recommended for everyone, if you refuse to compromise on your audio equipment, it’s time to get truly amped with the NuForce HA-200 Headphone Amplifier.
