Looking for an all in one streamer/amp for a den system

The only combo product that I had personal experience with was a Marantzstreamer DAC Amp many years ago and it was terrible, buggy on the streaming end, buggy and with non existent CS.

  I know the OP said one box, but given the size of the Wiim and the Bluesound Nodes, which are both just a tad bigger than wallet sized, I think the OP should be a little flexible here as either product will be barely visible sitting on an integrated amp.

Second the motion for the WiiM Amp Ultra which is due out third quarter this year.  I have the separate WiiM Ultra and Vibeamp units and think they are great -- fantastic buys for the money. The Amp Ultra will combine them into one unit.

I second the Sonos recommendation. This will give you good sound and greatly simplify placement. Aside from my main system, the rest of our house is all Sonos, and the sound is exceptional given the size and cost. I also have a Wiim amp with some Polk speakers, it is not even close to the Sonos setup.

I’d say KEF LS50 Wireless is a contender for streamline simplicity. Without speaker cables, makes it super easy to reposition..

Teacusa has very good deal on brand new or open box Teac NT-505-X. Excellent streamer.
