I would start with an Outlaw audio RR2160 mkii. It has really decent internal dac"s, FM, internet radio and a music streamer (with it’s own app) built in that you’ll come to love once you try it. It also has bass management which works far better than the cutoff filter on most subwoofers. Except for hdmi it has all the digital and analog in’s and outs that you’ll ever need. It also sports a 110W of high current power at 8 ohms and 150W’s at 4 ohm’s. The power is clean and the sound is neutral, articulant and has enough power to run most any speaker. It will grow with you if you ever decide to upgrade. At $999 this thing is an incredible value.
For the subwoofer I would go with an OSD Trevoce 10". I might even do two of them. These things are musical and punch way above their price point. Right now they are on sale for $229!
For the speakers. There are just so many great choices for the $770 budget you have left. If I could up the budget by $630 (cry once and get on with life ) then a set of Kef LS50 Meta’s would be a no brainer, but if the budget is firm maybe a set of Warfedale EVO 4.1’s would fit the bill.
That’s how I would spend YOUR money .
