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

Avoid hard to drive speakers. Speakers must accommodate room. What is size?
Amplification must accommodate speaker sensitivity and impedance.

Absolutely loudspeaker first. An efficient one would be a good idea as he won't be able to afford a lot of power. Perhaps the Klipsch Heresy or something like it. Then everything follows
Room size is probably 15x20, no smaller.

hilde45, or anyone with Raven.  I wonder if Raven Nighthawk would be enough for this size room?  Also would it drive a pair of small Martin Logan esl’s w/o woofer amp?
