I just recently got mine and have been using it with my Note 4 as well as my work and home laptops.  For IEMs I tried my JVC HA-FX700s and for headphones I used my Mad Dog Pros.  For speakers, I piped them in to my Audioengine A5+ set.   Initial impressions are that it seems with IEMs you get...

That's what it appears like. Of course it's not 100% these are final specs though. I backed it out of curiosity so only time will tell.

FYI from the Kickstarter:   DAC chip: WM8533 24bit/192Khz  Headphone AMP: MAX97220  output power: 125mW @ 32ohm  SNR : -108dB  DNR : 106dB  THD+N : -89.5dB  Crosstalk : -95dB  Recommend headphone impedance : 16~300ohm   There are no reviews because it's not shipped yet.  5 days left...
