Pulse Headphone Amplifier
 
You've gone and done it. You've spent a good amount of money on a set of headphones. You've spent time with them and you think they sound great. But can they do better? You know, you'll never realize the full potential of your headphones without proper amplification. You just won't.
 

 

Two Configurations

Pulse Headphone Amplifier is built using a 100% solid state topology. It features a fully balanced, dual mono design that rejects noise and wraps the listener in a precise and musical presentation.

Pulse Tube Headphone Amplifier is built with a hybrid solid state/tube topology with dual 6922/6DJ8 tubes in the voltage amplification stage, with a constant current source to make it more linear.

Circuit Topology

Pulse Headphone Amp's voltage amplification stage works directly with its analog volume control circuit. By doing it this way, it won't attenuate your music in the first buffer stage of headphone amp like other devices (which decreases the SNR performance). It's the best variable gain design available, maintaining a good noise floor and signal to noise ratio.

We know the importance of slew rate, which is defined as the rate at which voltage can change within the amp over time. Our current feedback structure is placed at the output, keeping Pulse Headphone Amp's slew rate above 2000V and preventing odd order distortion anomalies. Many of our competitor's slew rates clock in at only 20 to 100V.

To address the issue of power reserve, Pulse Headphone Amp's output stage keeps twice its rated power in reserve just in case you want the cannons in Tchaikovsky's 1812 Overture to feel like they're taking aim right at you.

Features as Unique as Our Backers

1. Ultra-wide bandwidth for high-resolution listening
2. The most versatile headphone amplifier on the market, outputting 100 mW from the 3.5mm output (perfect for IEM's) all the way up to 10,000 mW (for hard-to-drive cans).
3. No gain switch needed. Each output connector is optimized for the proper power output of what will be connected to it.
4. Fully-balanced analog volume control.
5. Fully-balanced precision DC servo on each output.
6. Instant Power and Current Feed technologies. You'll get the punch you need when you need it.
