The best streaming amplifiers and all-in-one systems
By Theo Mensah · Updated 19 June 2026
One elegant box, your speakers, done. From the do-everything Naim Uniti Atom to the vinyl-friendly Marantz Model 40n and the statement McIntosh MA352.

The all-in-one has quietly become the smartest way to build a high-end system. Put amplifier, DAC and network streamer in one well-engineered box and you remove a rack of components, a tangle of cables and a lot of expense — with surprisingly little sonic compromise. Add a pair of speakers and you have a complete, genuinely high-fidelity system controlled from your phone.
These three take different routes to that goal, from compact streaming convenience to a full-size statement integrated. All you add is loudspeakers.

Naim Uniti Atom
Rating: 4.7 / 5

Amp, streamer and DAC in one beautifully-made box, with the best app in the business. The default recommendation.
Marantz Model 40n
Rating: 4.5 / 5

Warm, refined Marantz sound with a phono stage and HDMI ARC, so it handles records and your television as happily as streaming.
McIntosh MA352
Rating: 4.7 / 5

A hybrid tube/solid-state integrated with the iconic looks and the muscle (200W/8Ω) to drive demanding speakers in a big room.
Match the amplifier to your speakers and room: the Naim and Marantz are ideal for efficient standmounts and most floorstanders in normal rooms, while the McIntosh has the power to drive almost anything in a large space. If vinyl matters, the Marantz and McIntosh include phono stages; the Naim does not.
Common questions
- What's the difference between these and separates?
- All-in-ones combine the preamp, power amp, DAC and (often) streamer in one chassis. You lose some upgrade flexibility but gain simplicity, fewer cables and usually better value.
- Do any include a phono stage for a turntable?
- The Marantz Model 40n and McIntosh MA352 include moving-magnet phono inputs. The Naim Uniti Atom does not, so you'd add an external phono stage.
- Will 40W be enough?
- For efficient speakers in a normal room, yes — watts aren't everything. For large rooms or demanding speakers, the McIntosh's 200W gives far more headroom.
Theo here. By day I write software, by night I argue with people on forums about whether bit-perfect playback is "solved" (it mostly is, and then it isn't). I cover the digital end — DACs, streamers, servers, the whole messy ecosystem of getting a file to sound its best. My promise to you: I'll separate the genuine engineering from the audiophile folklore, and I'll never tell you a $500 streaming bridge sounds "blacker" unless I can explain why.
