CEntrance DACport HD
What we think in the Inner Sanctum:
Improve the sound coming out of your headphones by adding the DACport HD to your setup. Instead of plugging your headphones directly into your computer or laptop, insert this thumb-drive sized digital-to-analog converter and headphone amp into a USB port, and then plug your headphones into it.
What does it do? For one, it bypasses your computers lousy soundcard and takes the digital signal from the computer and turns it into beautiful music the way your computer just can't. Then it provides muscle to power your headphones the way they were meant to be driven.
Technology has become so much more affordable and miniaturized that this amazingly small $200 device can do what it took thousands of dollars and a device about the size of a hard-back book to do just a couple years ago...and it does it better!
Pristine sound quality and the horsepower to make even hard-to-drive headphones sing; the DACport HD should be your next upgrade. Includes a real volume knob and a gain-selector switch (to best match your headphones).
