The Best Amplifier for the KEF LS50 Meta (An Owner's Ongoing Search)
The KEF LS50 Meta is a brilliant standmount that quietly demands a serious amplifier. I own a pair, and here is my honest, still-unfinished search for the right one.
Since 2017, the Naim Uniti Atom has been a top choice for audiophiles wanting one beautiful box that does everything. Years on, is it still the all-in-one to beat? Here's my honest take.

As someone who wanted a more minimal audio setup, I found the Uniti Atom to be the perfect fit. In this review I’ll share my experience and why I believe it stands out, but also who should look elsewhere. Before settling on the Atom, I seriously considered several other all-in-ones:
After reading reviews and watching countless YouTube videos, I was convinced the Uniti Atom was the best choice for my needs. Here’s why it’s held up.
A premium experience. The volume wheel is a genuine pleasure to use, and the whole unit exudes luxury. The build quality matches the price, this feels like a serious piece of kit.
Excellent control. The remote is straightforward and a joy, especially paired with Roon, Spotify, or AirPlay. Roon even lets you power the Atom on and off from your phone.
A genuinely useful screen. Seeing what’s playing and the album artwork elevates the everyday experience. It’s not touch-enabled, but I’ve never missed that.
Deep integration. Through hardware and APIs there are tons of options, I have a turntable hooked up, and my wife can hop on via AirPlay in seconds. That versatility sets it apart from a lot of integrateds.
Auto on/off. With my more modular setups, powering everything up and down is a hassle. The Atom is smart enough to turn itself off, and with Roon you can power it down from your phone. Small thing, big quality-of-life win.
The Atom carries Naim’s house sound: musical, refined, and engaging rather than clinical. There’s a richness and rhythmic drive, that famous Naim “PRaT” (pace, rhythm and timing), that makes it easy to listen for hours. Forty watts doesn’t sound like much on paper, but Naim’s amps punch well above their rated power, and the Atom drives most sensible speakers with authority. With efficient, well-matched speakers it sings; ask it to wrestle big, power-hungry floorstanders and you’ll start to feel its limits.
Look elsewhere if you need serious wattage for demanding speakers, or if you’d rather build a separates system piece by piece.
If the Atom isn’t quite right, these are the all-in-ones I’d cross-shop:
Years on, the Naim Uniti Atom is still one of the most complete and desirable all-in-ones you can buy. It’s not the cheapest or the most powerful, but for a minimal, premium, do-everything setup it remains a benchmark, and the one I chose. 7 / 10.


The KEF LS50 Meta is a brilliant standmount that quietly demands a serious amplifier. I own a pair, and here is my honest, still-unfinished search for the right one.

Past the honeymoon and the review-week hype, here is what living with the KEF LS50 Meta actually taught me: what they do brilliantly, the one thing they demand, and whether I would buy them again.

Could a single Arcam box do the job of my streamer, my DAC, and my amp, and finally give the KEF LS50 Metas the power they have been quietly begging for? I spent weeks researching whether the SA45 is the consolidation endgame or just an expensive shuffle.
