Audiophilleo 1

No other USB to S/PDIF interface gives you the same level of performance, features, and uncolored, spacious, transparent sound—not even at twice the price. And now get a Special Edition with 384Khz and DSD128 support.

Our unique design virtually eliminates jitter artifacts—the long standing bane of digital systems—to deliver an absolutely over-the-top listening experience from any Mac, Windows or Linux computers and music server—even iPad and Logitech Squeezebox Touch!
And now you can achieve the highest possible analog-like performance with the PurePower option, regardless of computer source or USB cable. Absolutely no high frequency noise from your PC can make it into your DAC because there is no electrical connection between the two. It has more bang for the buck than expensive USB cables or other external power supplies.
And it's so much more than just an interface. The Audiophilleo1's dynamic, multi-function, full-color display makes setup and day-to-day operation a snap. Every feature, from its advanced digital volume control, to BitPerfect validation of the signal chain, and in-the-field firmware updates, is readily managed on-screen. You'll be up and running in minutes.
There’s even a joystick for navigating the easy-to-read menus, which dim automatically once the music starts to play.
Only the Audiophilleo1 transport-processor has advanced RISC-based signal processing capabilities and a full complement of digital preamplifier controls—for less than one might pay for a USB interface alone. It's a complete solution that delivers exceptional performance and convenience in a single, compact package.
