I just got into speakers as a long time headphone dude. My last headphone was the Susvara, and it suppose to be one of the best endgame headphones. I was driving them with Pro iDSD and Soundaware P1, an unknown but excellent headphone amp.
I paired the Atom with KEF LS50. The improvement is astronomical going from headphone to speaker. The Atom may be one of the best engineered and thought-out piece of audio hardware. Switching from Tidal to Coax input to UPNP server happens instantaneously without a hitch. Most of all, its synergy with the LS50 is just purely gold.
I may go up to one of the Focal offering later this year like the Sopra N1 or Kanta 1.
