I'm a big fan of the all-in-one streaming/integrated amp. I bought a used (mint) NAD M33 around 6 months ago and I love it. Granted, it's a lot higher end product than this C700 but still, conceptually I love it.
BluOS as a streaming platform is fantastic...super easy to use and I can stream pretty much whatever I want. A simple, 128GB USB stick stays plugged into the back of the unit holding my personal music collection...no clutter or CD's.
