Rebadging of Streaming Platforms

So I was reading some Q&A from an audio reviewer last night in which he mentioned that most audio streamers are just rebadged platforms from one or two vendors (I'm talking just the streaming portion of any unit, not the DAC).  I have had more than one dealer tell me the same thing.  So my question for anyone who knows is who actually makes these one or two platforms?  Or conversely, who actually makes their own streamers?  I going out on a limb and am guessing that Sonore may be one who "makes their own" but was hoping some one else had the actual answers.
