Don't split the atom, unite it – Kinda. Naim's Uniti Atom Headphone Edition [$3'290] takes away the original speaker amp then replaces it with a dedicated headphone amp with XLR4, 4.4mm Pentacon balanced and 6.3mm standard jacks. Everything else remains unchanged. It's still a 32/384 USB DAC with RCA/XLR pre-out, integral streaming from Qobuz, Tidal, Spotify, Internet radio, AirPlay 2, Chromecast and Roon Ready plus one analog RCA input, 2 x Toslink and 1 x coax. Then there's the best volume knob in the business. Headphones, ask what's in a Naim. Then unite yer atoms.
