I mostly listening from my CD player and PC (flacs, HDTracks 24bit/96 and 192Khz files) with my Sennheiser HD650, so I decided to buy this NuForce Icon HDP as a DAC and headphone amp combo.
 
It is very decent DAC/Amp. It gives a more balanced, clean and transparent sound to my Senn 650. The build also has a very nice finished and touch. Overall, I'm satisfied!
