Trouble Understanding an Ad.

I am thinking about upgrading to a stand alone DAC so I have been perusing US Audio Mart. I came across an ad listing a Moon 280D as well a a Moon MiND V2 Streamer. If I'm understanding right these are separate components or am I wrong and this is a Streamer DAC? For some reason an Emotiva Tube amp is in the pics, at least that's what I believe it is. There is no way to contact seller. What am I dealing with?
