I bought this DAC after reading about it on audiosciencereview.com. It lives up to the hype and sounds fantastic with my JDS Atom headphone amp and Sennheiser HD600 banks. I got everything for less than $400 (bought used Senns off Ebay and replaced pads for less than $200). Ideal for headphones on my desk when I don't want to turn on tube amps. You need a suitcase, but there are many options for this. I suggest the one with the rounded sides in the DIY thread at ASR. It works and it's cheap.
