headphoneaddict, you compare the NuForce headphone amp to Meier HeadSix ($160),iBasso D2 ($160), and Apogee mini-DAC ($700)? Do you have the upgraded PSU unit?
"At this point I am really liking the Nuforce as a headphone amp, very much. I highly recommend it - it seems to drive ALL of my headphones well, including HD600, D2000, RS-1, Yamaha HP-1, Edition 9, etc... They could be charging twice as much money and I would still buy one."
What I want to know is that can the NuForce drive the K702 cleanly? I'm not talking Heed Canamp level, but can it give it enough power so the K702s sound acceptable?
For speakers, I'm going to drive Energy RC-10, which should be a good match (88dB)
Also, what does the preamp on the NuForce do? Just control volume? Why is there a preamp out? Is it used to connect to other DACs/amps?
P.S. As it is a Class D amp, is there noise/static?
