Another Possibility:
Rogue Audio Pharaoh integrated over on TMR $1.8K
Schiit Gungnir DAC new $800
Bluesound Node on TMR $500
just a tad over budget. easy to set up. People here can get you going on the hookup. But do your own research on that amp to make sure it matches up to speaker specs
Also a Hegel H95 over on usaudiomart within your budget. Has internal DAC so you could skip the Schiit with that unit and got strait from BS node to amp.
Too generalize to maximize SQ.
Streamer---->DAC----Integrated.
BSNODE-->Schiit-->Rogue
You can find and integrated with a DAC (Like the Hegel) if you want to keep it simple but many times specialized DACs do better. They are almost always better than the DACS in streamers at the BS node price point.
