B&W Formation duo vs Naim Uniti Nova

I have the B&W Formation Duo with a Roon subscription today, and I really enjoy the simplicity and also the sound quality.

I am now considering buying a set-up like Naim Uniti Nova and the B&W 805 D4, and still using Roon. I feel like this will still be an easy setup to enjoy function wise and it will still be a small system when it comes to cables and stuff.

Can I expect a better system when it comes to SQ and are there other benefits?
