Pros: Power, detail, clarity, gain stages, multiple inputs

Cons: Size, weight

The Theorem 720 is magical.. Using it is like stepping into a foreign land where everything is crisp, detailed, and so very vivid that you’ll never want to leave again for the boring, veiled, blurred and blobby images of your old homeland.

I tested my Theorem with many different genres of music, from Rock to Rap (Eric Clapton, Eminem, Pink Floyd), Pop (Michael Jackson), and jazz to R&B (Sade, Michael McDonald, Brian McKnight, Seal, Usher) using my iPod Classic 6th gen (120GB) and the provided CL LOD paired with my modded T50rp and Shure SE215Ltd w/balanced cable, JH16 Pro, and Grado SR80i, and it didn’t ever disappoint. I’d go so far as to say that it rivals even some desktop setups; A portable powerhouse indeed!

The DAC: The DAC that CL implemented in the Theorem 720 is an amazing little piece of engineering that meshes perfectly with their own first class product (obviously, right? ). You get extremely good detail, great soundstage, and the clarity is just… Phenomenal.

The Amp: I LOVE the amp section of the Theorem 720. The amp is very neutral, but not analytical in any way. It is neutral while still having a very clean, very natural and musical tonality. It has a very black background with my T50rp, and a slight hiss with my SE215Ltd and JH16 Pro, that quite honestly is negligible, since it’s only heard without music playing.

The Treble: The Treble on the Theorem is very nicely extended, never sibilant, with a perfect amount of air around the top end that adds to the naturalness of the sound.

The Midrange: The midrange is spectacular. Vocals are so vividly reproduced as to be almost palpable… They have a very lush, very organic quality to them that makes them much more enjoyable than they would be through most anything else you would normally listen.

The Bass. The bass, when played through the Theorem, is a thing of wonder. Where once upon a time, your bass note was just that – a single note, now they are layered, and detailed, and reproduced in a way that makes them sound almost sophisticated. The Theorem doesn’t have the most impactful bass, but it more than makes up for that in it’s portrayal of detail

This is an amp in a class of it’s own, and definitely worth its asking price, and more, if you’re asking me. An amazing value for the money, I wouldn’t hesitate to recommend the Theorem to anyone. On top of everything else, it has really well implemented gain settings that will provide more than enough power to any headphone you might own, and it charges iDevices to boot! I look forward to my next Cypher Labs purchase and I know, from personal experience, that it will ooze the same quality and sophistication as the rest of their products, and Cypher Labs as a company, do.

Cypher Labs Theorem 720 DAC Headphone Amplifier
Description:

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.
