I’m looking for an sleek integrated amp under $15k

@soix   Sleek not slim. That unit is pretty ugly IMO Lol 

Chord always has cool looking gear that is generally quite well regarded.   I have a Chord Mojo that sounds great and is very cool looking with multi color buttons and all … 

If you want a nice display on the unit Cambridge Naim and HiFi Rose are the go tos. The Hifi Rose integrated probably stands out if video will be part of your game.

I think Rotel just came out with something along those lines but may not be much info out there about it yet.

Oh and I would also consider NAD m33.  The room correction that comes with that can be a game changer.  
 

I went through similar choices recently and landed on the Canbridge Evo 150 and love it.  Originally I was looking at the m33 but went with the Cambridge which cost a lot less and actually had more input and output options I needed.  But the extra power of the m33 is a plus as is the room correction.

But you think the Naim Unity Nova is good looking?  Seriously???  

Maybe you are just baiting us with that price and then wanting features but not even mentioning musical quality.  Really the display and slickness do not necessarily go coincident with amazing sound.  Someone Mentioned the Boulder.  The Audionet Watt sounds great.  The Soulnote A3.  You might be better with an external DAC.  There are many others Moon...but save money if all you want is cool display and a pretty face..
