Help with a system for a friend

 A friend asked me to help him put together a stereo system for under $6500. I think there’s no better place than here to get answers. He listened to my system and enjoyed it. I have Bryston equipment and aerial speakers, schiit dac, and a Sonos for WiFi.  It’s a detailed, transparent clean sound, good damping.  

His needs are simple.  Integrated amp, speakers, and a music streamer for WiFi.  No vinyl.  All new, no used.  I’m going to steer him away from hegel (no need to discuss this).  Any suggestions?  Leave room for cables.
Thanks
