Best sounding compact integrated amp < $2k?


I am putting together a 2nd system that will be used in my living room.  Music source will primarily be Tidal.  Haven't finalized my speaker selection - but I may end up going with something from Dynaudio - perhaps the Excite X18 or the Special 40.  Streaming will be handled by one of the following: Bluesound Node 2, outboard DAC/streamer or DAC/streamer onboard the amp.

Need to figure out what integrated amp would work best.  A major constraint is that the enclosure that will house the amp has a maximum depth of 15 inches - so the amp itself will need to have a depth that is a couple of inches short of 15 (to leave room for rear cables/connections).  

I have tried the Naim Uniti Atom and it is certainly a potential solution (sounds great too), but I am hesitant to go with an all-in-one solution (a separate streamer allows me to upgrade that part of the system as technology progresses).   

The Peachtree Nova 150 is another option - but I have not yet had an opportunity to audition it.  

My budget for the amp is $2k, but I am willing to stretch the $$$ for an outstanding component :)  I am also open to picking up a pre-owned amp, though I would prefer to buy new. 

Suggestions will be *greatly* appreciated!

I have the Belles Aria hooked up in a cabinent the same depth the orginal poster mentioned and it fits like a dream with cables connected (spades for speaker cables)...yes the Aria doesn't have streaming or DAC, but they mentioned that they were considering a separate to handle that fucntion.  
Interesting thread I wonder what will Vingard go for?  The Hegel H90 looks interesting but in one review it praised all else as to sound of the Amp but also stated that it's DAC was the weakest link, so it somehow defeats the main aim of this amp? (whats the point of the DAC if one ends up using an outside DAC as happened in that review - HIFIChoice) Naim Uniti Atom looks good if one enjoys their particular sound (excitement factor enhanced slightly - can be addictive), Naim's Customer Service is very good and their following is a little bit like a cult following by audiophiles. 
Been auditioning, reading, researching, YouTubing - as one does in such scenarios :)

Decisions will be forthcoming...
Don't forget Sugden! I was listening to their integrated about a year and some ago, and it is just a pleasure.
Focal Shape 65 speakers (or quite frankly any other good studio monitor, Dynaudio makes plenty) hooked up to Chord Mojo being fed by Google Chrome Audio via TOSLINK cable will blow away systems costing 5x the money. That's what's in my office (with IFI iTube2 between Mojo and speakers) and I often wonder if it doesn't sound better or at least as good as my other systems, some around $40K price tag. Active speakers are the future. How about a pair of KEF LS50W?
