The Cypher Labs Theorem 720 DAC is a powerful battery powered portable headphone amplifier and digital to analog converter. The Theorem 720 DAC streams bit-perfect digital audio from Apple iPadTM, iPhone® or iPod® devices, some Android devices, and PC/Mac to headphones and powered speakers using USB Audio for superior audio quality.
Why do you need it? Easy, it makes the music sound so much better! Even audio novices can hear the difference right away. Just connect combining it with the Theorem 720 DAC will deliver the music you've been missing.
The Theorem 720 DAC is made for portability. Now it is possible to have desktop quality audio wherever you go: train, bus, plane, office or home.
How does it work? Currently, Apple iPadTM, iPhone® or iPod® deliver compressed analog audio, whether from the headphone output or analog line out. Even playing a high quality track results in down-sampling. Even computers process the audio output poorly. The Theorem 720 DAC uses advanced digital processing and an audiophile grade digital to analog converter to provide audio at a high resolution, bypassing the Apple/Android/computer internal DAC and analog circuits. Played through the Theorem 720 DAC, a high quality recording will sound equivalent to or better than CD quality. While there are many music formats, and lots of opinions about which is best, we recommend using Apple lossless, which plays efficiently and doesn't take up too much storage space.
A lithium-ion battery powers the Theorem 720 DAC during travel.
