Hello @cundare2 !
You have some nice options and seem headed on the right track with Ayre, the older on newer Naim 200 series and Coda. I have heard two others that I like.
The Audionet Watt weighs 55 pounds but is very very good. It checks all the other requirements. I have heard this in my system and it takes a lot of money and weight to top it. At their rating of 167w @ 8 ohms I would not worry about power. GTT Audio often has a show demo of this model.
The other are the Soulnote A2 and A3. the A3 is too heavy at 66 lb but super nice. I own the A2, and even rated at 100 watts it punches well above that. My speakers are more efficient though. But very sweet sounding SS integrateds. I got my A2 barely used for 4k. I see them very occasionally for 5k.
Good Luck! Fun!
