A one-box solution will generally not outperform separates at this price point, i’m not sure why you are comparing a Nova to them?
Yamaha power amp + Hegel are completely different brands with different sound signatures than Naim.
Same for Supernait 2 + ATC SCM40. Those ATC speakers are completely different from the Dynaudio Special 40’s in terms of timbre and style, you can’t compare them to each other.
