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 a Naim Uniti Atom right now - but I have owned and like Hegel products.  Can you tell me the appreciable differences - other than power output - between the H90 and H190?    I have read articles on both saying they each is excellent.   Is the H190 worth an extra $1200 for a small room amp using ?  Is the detail, separation, etc. that much better on the H190?     Thanks
I am using Legacy Studio - Studio HD Speakers on stands.
larryl50, as much the H90 is a fantastic piece, the H190 is in another league and not just in terms of power. It should be though for the extra money. Better DAC quality, better amplification, better preamp section, etc. Really, it just sounds considerably better across the board in my opinion and I feel is their best value integrated. If using easier to drive speakers, I'd say that quality-wise it goes head to head with the H360. But, the H360 has the ability to drive some speakers that the H190 can't due to the extra power. So, while the H90 is a great piece, if you can afford the extra money for the H190, that would definitely be a very nice upgrade. Also, the H190 has a XLR input 
Thank you for your response.  Any thoughts on the H190 vs a Simaudio Moon Ace?
