Advice on ‘’pre-amp’’ upgrade

So after a long time selling and buying my stuff I got the funds to buy something nice. Just by luck I got interested in a UnitiLite bt I saw in the showroom of the dealer I’ve visited. The classic look with the green informative screen got my attention so I asked what it was. The salesman told me the whole story and demoed the UnitiLite with his iPad and his music collection he had stored on a server somewhere in the showroom. I felt in love and I wanted to buy it so I did. 

Now one and a half year later I am still enjoying every bit of my UnitiLite, but with a different set of speakers and a NAP 200DR connected to it. Everything tells me this is the end of my Hi-Fi journey as I love the looks, the sound and the functionality of my system. 

Yet there is a small voice in my head to go further up the ladder and as I am browsing through the second hand market app, my eyes saw the NAC N-272. With a bit of luck I can get enough money back for my UnitiLite so I have sufficient funds to get the N-272. There isn’t really a direct comparison between the UnitiLite and the N-272 and on the first sight they look very similar. Though with a bith of research I came to the understanding the N-272 is certainly further up the Naim ladder. 

My system consists of the UnitiLite bt, NAP 200DR and Dynaudio Excite X18. It is used on a daily basis with streaming Tidal, listening to vTuner internet radio (>256Kbps) and watching series and movies. 

What is your opinion as a Naim expert on my story? Should I upgrade and enjoy even more of my system (and stay there for a couple of years) or isn’t this a very good upgrade?

I am curious...
