I got a shipping notice on 4/17 and received my GEEK Out 450 today. This thing is REALLY good, and was easily worth the wait for me. Definitely better than the HRT Microstreamer on first listen. Need to build a new cable to hook it up to my Schiit Vali and an adapter for some of my headphones before I can give it a good comparo to my Nuforce HDP and cDAC+ as sources and a combo.
Can it drive the HD800 OK?
