Description

HC1 High Current Headphone AmpThe HC1 is an expandable, high powered headphone amp designed specifically for critical studio monitoring. The HC1's circuit employs parallel amp stages for greater power and lower distortion. This parallel opamp concept has been known in theory for decades and was put to practical use in Douglas Self's "5532 OpAmplifier" power amplifier. As a result, the HC1 sounds clean and clear even at high gain and when driving low impedance headphones. Because

The HC1 is an expandable, high-powered headphone amp designed specifically for critical studio monitoring.

The HC1's circuit employs parallel amp stages for greater power and lower distortion. This parallel-opamp concept has been known in theory for decades and was put to practical use in Douglas Self's "5532 OpAmplifier" power amplifier. As a result, the HC1 sounds clean and clear even at high gain and when driving low-impedance headphones.

Because everyone's monitoring needs are different, the HC1 is designed to be customized. The power and audio input connectors are screw terminals, so you can attach whichever jacks you need without soldering. You can also daisy chain multiple HC1s to make a multi-channel headphone amp.

The HC1 is a great project for intermediate builders who enjoy the challenge of choosing their own chassis and inputs.

For your big head instead.
I bought these in anticipation of my upcoming lasik procedure. These things look great and the seller even included a cleaning kit in box. As someone who is 6'3" with a larger head, these sunglasses are snug without being uncomfortable. I actually love that since my current prescription sunglasses are so loose on my head that they can fall off during light activity or when I sweat. Now that I have my pick of the litter with sunglasses, I could not be happier with the money I spent on these and the quality that comes with them.
