EarMen Steps Up with CH-AMP Fully Balanced Headphone Amplifier
After attracting a strong following with its small portable devices in the headphone market, EarMen Audio is back with its CH-AMP fully balanced headphone amplifier with excellent features and a linear power supply unit.
The fully balanced architecture is a welcome inclusion for desktop head-fi enthusiasts, along with gain control, output power up to 3.8 watts, and a claimed "ultra-low THD and SNR".
EarMen says it has utilised a composite amplifier topology, with "the composite op-amp bringing the best of both worlds with excellent DC and AC characteristics." The company continues:
These amplifiers offer several advantages over other types of amplifiers. Power amplifiers typically use thermal feedback loops, thus causing serious errors while driving heavy loads. These errors occur due to self-heating. The use of the composite can remove such errors and improves the performance of the circuitry. The composite amplifiers also offer better DC output offset. The excess of the load placed on the output transistors does not affect offset voltage.
Adding to overall performance is the inclusion of a linear power supply that the company says "made without compromise, using the best components and the latest circut design. EarMen Linear power supply is reliable, simplistic and produce minimal noise."
For the full specifications, visit the manufacturer's webpage. Available now, the EarMen Audio CH-AMP will sell in North America for $1,480.

applause awards
Each time StereoNET reviews a product, it is considered for an Applause Award. Winning one marks it out as a design of great quality and distinction – a special product in its class, on the grounds of either performance, value for money, or usually both.
Applause Awards are personally issued by StereoNET’s global Editor-in-Chief, David Price – who has over three decades of experience reviewing hi-fi products at the highest level – after consulting with our senior editorial team. They are not automatically given with all reviews, nor can manufacturers purchase them.
The StereoNET editorial team includes some of the world’s most experienced and respected hi-fi journalists with a vast wealth of knowledge. Some have edited popular English language hi-fi magazines, and others have been senior contributors to famous audio journals stretching back to the late 1970s. And we also employ professional IT and home theatre specialists who work at the cutting edge of today’s technology.
We believe that no other online hi-fi and home cinema resource offers such expert knowledge, so when StereoNET gives an Applause Award, it is a trustworthy hallmark of quality. Receiving such an award is the prerequisite to becoming eligible for our annual Product of the Year awards, awarded only to the finest designs in their respective categories. Buyers of hi-fi, home cinema, and headphones can be sure that a StereoNET Applause Award winner is worthy of your most serious attention.
