WTB External Amp/DAC

I am looking to buy an external Amp/DAC for my Sennheiser PC 350's now that I have switched to ITX and can no longer use my sound card. I don't want to hear you rant about how I don't need an amp and that my onboard is fine yadayadayada. My onboard is not loud enough. And there is also a little noise interference. I was looking at either the Fiio E10 or E07K. However I am willing to buy used to save a little money. What have you guys got? 

I am open to other comparable Amp/DACs as well, new or used. It all depends on price. 

Thanks, cryptnotik.

I prefer tube so a little tube amp . The bravo audio v2 made a nice little preamp headphone amp with a tube swap to a groove tube . Going from onboard dac to an external dac seems alittle redundant.

 

Well a lot of the cheaper Amps like the Fiios have a DAC too. I want a USB dac, not analog.

Here is a thought? Did you know some of the best sound systems in the world are a mix. http://www.youtube.com/watch?v=WZHjRe-hm_s

I've got a Schiit Magni and Modi that I've been using less and less. Check out some reviews and let me know if you're interested. :)
