    Many thanks for this :)

    Im having a tough choice between the theorem and hifi m8
  2. PolkManiac
    The HiFi M8 is more versatile but is larger, the Theorem is smaller and has a much longer battery life and will charge idevices, but doesn't have as many connections. They both sound really great, so it comes down to what you want.

    What is your music genre ?
    What kind of headphone do you want to pair with ?
    Is that two T5p and LCD XC?
  4. redstar
    Its the LCD-X. Thats my primary concern. Im hoping it would work well as a desktop solution, as i will use it slightly more at home than on the road. The LCD-X are my main cans.

    When i take it on the road, i will use the Sennheiser momentums.
    The T5P was just something i was considering, however i would probably get an IEM over that, such as the shure SE846.

    Music i listen to is, fast and aggressive tech-punk and hardcore punk.
    I also listen to a lot of progressive instrumental soundscape music and 80s inspired synthwave.

    Theorem is excellent Dac / Amp for IDevice can drive your headphone like LCD X , T5p and your Momentum in audiophile SQ .
    I think for Shure 846 you can hear the hiss , this the only minus from Theorem is hiss for BA driver iems or ciem

    For your taste of music, you will hardly recognize the hiss from the Theorem.

    Just snagged the 720 for use with my iphone 5. A change of pants is in order.
    I'm coming from an amped iphone 5 line out (30pin adapter, L9, E12) which sounded rather good, but amping chit simply equals a slightly larger chit 'nomsayin?
    It's like going from a '99 Honda to a 2014 Corvette Stingray
    I need time to absorb what's going on. I'm left rather speechless with the improvement. Hold me guys
  8. midnightwalker
    Lol such a nice impression [​IMG]

    Thank you sir. 
    On a serious note, I'm looking for either an aftermarket, custom made or parts to create a custom length Lightning to USB Mini-B connector between my iphone and Theorem. Any help is GREATLY appreciated!
    I'm familiar with soldering, shrink wrapping and the like. Preliminary searching has lead me to believe I'd be more likely to have a threesome with 10/10 Russian twins than find the cable I'm looking for. 
    Even if you know a place that sells the stock lightning cable (that comes with the unit) would be useful as I can most likely butcher it and make it shorter. I know it comes with two lightning cables, but one is 100% defective out of the box. Maybe I'll bother the local store or Cypher Labs for one later...

    I've borrowed a Theorem 720, which I've been using for a while. It makes for a very nice DAC and amp for full-sized headphones, or just as a DAC for a larger amp. Not so great with IEMs, as they have a lot of hiss.
  11. big mac
    i  thinking about buying theorem 720 amp is it worth a upgrade over the e12 amp . my headphone that i own are sennheiser 600 and mad dogs.
  12. Ultrainferno
    Of course
  13. big mac
    is that the best portable amp to drive my headphones. it lot of money to spend on a portable amp.
  14. Ultrainferno
    It's not only an amp. You can look at the Duet, C5, International and a whole bunch of others
  15. big mac
    what about centrance m8 as portable amp and dac.
