Cypher Labs Theorem 720 DAC: A New Portable 24/192 USB/iDevice/Android DAC & Amp

Very nice looking unit with a great set of features.  Love the battery lifespan. The box size is still very manageable. I'm not inclined to a balanced potable setup but if it's only a question of recabling my phones then this makes it a possibility. I love my other Cypher labs products except for the wall warts. I'm peeved the 720 needs a wall wart to recharge and would have liked it to recharge via USB as well but I do really appreciate the thought they have put into the wall wart itself. It packs flat, it's (kinda) small and has a shiny red cable.
 
Sadly, I'm an IEM guy - as must be a huge segment of the possible market for this device - so the noise floor is a deal breaker to me.
The fact that it's not available in silver is just extra reason for me to stay aloof.
 
I really, really want one though. This is very close to the feature set I want in my portable idevice.

Why do you never talk about VentureCraft products? They're available to the international market and offer similar features to the M8 and 720 as well as other unique functionality (such as the TT which is a portable DAC/Amp with tubes).

Well at least Jude mentioned the VERZA, and to be honest, I think the M8 and CLT720 are on a tier above VC/V-MODA, as least in terms of configurations, power, battery, and price.  VC is aimming for technical advancement like portable tubes with the TT, or master quality source of DSD and up conversion with the SounDroid Typhoon, vs. CEntrance and Cypher Labs on improving existing tech and SQ.  However, like a lot of other poeple have said before, if CEntrance can pull off 24/96 native res for their M8, which the T720 can only do 16/48, then it will change the game completely.

Looks nice. It is a shame it does not do well with ultra high sensitivity iems, but it's crazy that something like this is even allowed to exist in terms of people are buying it and it's a product that is viable in the current market.  Pretty awesome.

  David, same AKM DAC stage as in Solo -R and -dB?
 
If so, how does the Theorem built-in headphone amp compare to the Solo stacks you guys presumably have in the office? Cheers

 
Emailed David instead. Below is an excerpt. Super quick replying btw

The DAC section is basically the same as the Solo -dB, both will process 24/192 on computers and some android devices. Apple devices are more limited, but still very high quality with 24/96 on iPad2 and above, 16/48 on other Apple devices. You can also use a FLAC player app on the iOS devices (not Classic). I have a blog on this topic somewhere on the website.
 
The audio quality is in my opinion better than the Solo -dB + any other portable amp. Maybe I should make an analog amp to go with the Solo -dB. :)


I have more reviews in the works.
 
I have a lot of amps here and the goal was to be the best.
