Upgrade Your USB DAC to Asynchronous 24/192
USB inputs on many DACs don't support resolution beyond 16-bit/48kHz. The Peachtree Audio X1 USB-to-SPDIF converter provides an easy upgrade for your USB DAC. It interfaces your computer's USB port with your DAC's coax or optical SPDIF input. The X1 lets you fully enjoy the highest-resolution digital music available, all the way to 24/192. And it includes native support for the popular 88.2 and 176.4 sampling rates.
The Asynchronous USB Advantage
Timing errors known as jitter cause digital distortion. The X1 keeps timing errors at bay by not relying on the audio clock in the computer. Your computer's internal clock can get thrown off time by the thousands of processes running in your operating system's background.
With asynchronous USB, the precision audio clock in the X1 takes control of the flow of data coming from the computer, resulting in significantly lower incoming jitter and superior sound quality. Asynchronous benefits all of your digital music files, from MP3 to 24/192 high-res. If you don't have an ESS Sabre based DAC, we highly recommend using asynchronous USB.
Bit-perfect Feed into your DAC up to 24/192
The X1 uses two crystals for accurate playback of the various sampling rates of your digital files with native support for 16-bit and 24-bit: 44.1, 48, 88.2, 96, 176.4, and 192 kHz. Many USB inputs on DACs rely on a single crystal with native support for one sampling rate multiple. Using one crystal per sampling rate "family" results in superior timing and clearer sound than single crystal solutions.
Transformer Coupled Digital Output
Computers are prime sources of electrical noise. Electrical noise can be an audio intrusion that you can't hear directly, but which can mask fine details and distort the tone of music. A pulse transformer on the coax output isolates electrical noise so only the pure digital bitstream is fed to your DAC for noticeably quieter backgrounds. The optical connection is inherently isolated from electrical noise. Whenever possible, use the coaxial digital output for the best sound and for its superior bandwidth when dealing with sampling rates above 96 kHz.
USB Class 2.0 Compliant
The X1 is USB Class 2.0 compliant, making it plug-and-play on the Mac OS X operating system. For Windows (Windows XP, Windows 7 and Windows 8), a small easy-to-install driver is needed to unlock 24/192.
The X1 is powered by your computer's USB port. No awkward wall wart power supply is needed.

|A Real Peach...|
I have a modified AudioNote Dac Kit 1.1, but it only accepts a coax digital input or balanced and I bought this Peachtree X1 USB-in to Coax-out converter so as to play my Foobar loaded ripped music collection and my favorite streaming internet radio music from the likes of Digitally Imported, Shoutcast, PolkaStacja, etc., via Winamp, through the AudioNote. Foobar outputs a 24bit signal from my digitally ripped music at 14441kbps..while Winamps radio station playlist outputs at anywhere from 128kbps to 320kbps...AND this Peachtree X1 converter makes all of this music sound fantastic, either through my ATC SCM12SL speakers or AudioTechnica ATH-W5000 headphones, both via tube/hybrid based amplification. I also ripped some cds at 320kbps for playback in my Mazda 2 via the Soundfly AUX digital interface that accepts a flash drive filled with max 320kbps music files. Playing these fairly low res 320 ripped files through this Peachtree X1 and into the AudioNote Dac Kit, I sit amazed at how finely delineated this music sounds. Bass lines are clean and easily followed, which really puts the drive to the rhythms, while complex, high energy music like Yello, or Gotans electronic Tango styles, are fully fleshed out and take the listener propelled along with the music. This Peachtree X1 is a revelation to me. Im really amazed how great even low res digital music sounds through it. It was very easy to get it to work in Win 7 64bit via its on line driver support, and its been working just fine now for a month plus...no hiccups, at all. If you would like your coax input only dac to play USB based computer music, I recommend you give Audio Advisor a call to buy this one...the Peachtree X1. Works for me...beautifully.
