I’m not an audiophile so I can’t describe the sound in an overly detailed way. I will provide you with a few comparisons to the Naim, why I bought it. Also, I won’t review or post a product unless I am seriously impressed with its performance. I return a lot products and I almost returned this one before I realized you could EQ it using a pc (or Mac). I’m using this in a 2.1 setup. The gray box is a 10” sealed sb acoustics with passive radiator and 300 watt Dayton amplifier.

The app sucks compared to the Wiim amp where everything imaginable is adjustable at your finger tips HOWEVER, the Naim has downloadable software you can install on windows or Mac and really tweak the settings. Not only does the Naim program have preset profiles for Focal speakers, you can fine tune the EQ speaker outputs. See photos. Set high and low pass filter, and filter any freq.

The Wiim amp will be more than sufficient for most with bookshelf speakers in a 2.1 setup in a small to medium room. I have a larger townhouse with high ceilings using Dali floor speakers. The Wiim powered them surprisingly well, however it took some volume to hear decent dynamics. With the Naim, the volume can be low and the dynamics is much more robust. Out of 100, at 32 the Dali’s sing. I also wanted a more powerful version of the Wiim that has e ARC, and that was compact.

I have used a Cambridge evo 150 and NAD c 379 and the Naims clarity, dynamics, and feeling of having sheer power at your fingertips is equal to the Cambridge and I feel has a more “robust” sound signature than the NAD. I really wish I knew the type of class d module they are using. The sound is exceptionally clear. Not overly boring or sterile.

There is no EQ within the app other than independent source volume control. It’s mainly to pair up your streaming services such as tidal or Spotify. There’s other options in the app for loudness, max volume, time zone, too many misc options to list but if you want to know a specific just ask and I’ll tell you.

I wouldn’t display this thing on your shelf. It looks like a router. A really heavy router. The “audiophile feet” was more of a gag (and so it would slide around easier) and to display how thin this thing actually is.

Who this amp is for: the DIY audio crew who have put many hours in tuning a system. The downloadable program gives warnings to the user about damaging their speakers “meant for professionals”. You have to use the program out of the box to set it up so this will turn a lot of people off however if you spend an hour with the program it’s pretty straight forward. There are terms I wasn’t familiar with on the program and also filter types I’ve never heard of. I mainly stuck with the high and low pass. Or those who want to rack mount an integrated. Naim has other multi channel power amps that you can link up to this streamer.

I also wanted to add that I needed the e-ARC capabilities so there is only 1 remote control for the TV. My young kids use the TV and want them to be able to use the simple remote. I put a volume limit on the Naim so they wont blow anything up. Past 60 is scary db levels.

Any plans to return it back or it sounds as expected?
 
I am impressed at its functionality and price for a NAIM! It’s cool to see Dante support. I would consider a preamp version with XLR outs. I have my Bluesound Node Icon in order but this seems like a compelling alternative too.
 
:) thanks for letting me know, I just placed the order
What do you plan to use it for? Will you be using it for arc capabilities to? Make sure you download the desktop program so you can fine tune it.

I have an icon too with a purifi buckeye amp. The Naim sounds better with my current speakers and room. Louder and more dynamic. The purify/icon combo is honestly “perfect” soundIng, but it’s kinda boring or sterile for me. The Naim is more compact too with the height of 1.5”. Only thing missing is a headphone option. I’m going to test the marantz 40n. everyone raves about the sound signature of that amp. I’m learning that I tend to gravitate towards amps with a sound signature.
 
Does it really come with those garish feet? The whole 'microphonic' thing with some Naims (decoupled connectors and so on I'd suggest, is more 'marketing hence subjective pre-programming' than any objectively or blind-subjectively proven thing.

Naims used to be about the most 'characterful' solid state amps out there, rather like a tamed PA style of a brightly lit, forward tone with narrow and rather 2-D soundstage we used to like in younger days. I like to think the excesses have gone now, but even the Statement amp with their silly-money digital source and woo-cabling gave me listening fatigue one afternoon into top Dynaudio speakers, which didn't do this with other amps I subsequently heard them with.

I got the unit a few days ago and I like it , my personal score for what I use it and for the money I paid, will be 99 out of 100.

It would be nice just to have a volume control knob to make it easier to use it without using the phone all the times.

What I like the most compared to uniti atom, which I returned 3 units because all sorts of problems, it is very stable, not even the smallest issue except I'm still trying to figure it out how to use Chromecast and play music or movie trailers from YouTube.

Probably on uniti atom the sound was much better, and I mean only for some lower frequencies( the double bass instrument was more accurate, if I'm not wrong with the name of the instrument), but I couldn't go over the other problems.

Uniti atom list with the issues I had on 3 different units, not all the problems were on every single unit:

Screen wasn't turning on sometimes for a few hours no matter if I put it on deep sleep or just restarting it.

Popping noise from speakers when turning them on and off.

The turning off popping noise had something to to with upnp, Chromecast or auto hdmi, I turned all of them off and I got rid only of the turning off popping noise, so is not a "naim thing" is just a problem with one of these modules.

Volume knob not responding sometimes.

Getting very hot and a humming noise when usb flash drive was inserted.

I had to give up and move to something simpler to meet my needs only.

Most of the time I use the phone to control it, but probably 5% of the times it would be nice to have a remote or volume control knob.

The app is very stable and easy to change settings.

It is small, elegant and it does the job.

I only use it for internet radio 90% of the times, a little bit for tv and a little bit for tidal, I don't need all the other inputs available on the atom.

It has Hdmi but I prefer digital optical, because it won't cut out the tv speakers.

I set the limit to 50% and if I go from 0 to 100 it will be loud enough to annoy the neighbours, the remaining 50% are probably for those who want to damage their ears.

To make a comparison with my Klipsch the fives, the 50% on uniti 102 it is a lot louder compared to maximum on Klipsch the fives without any distortion, I hope it makes some sense.

My speakers have a lower sensitivity of 86db and they work great with uniti 102.

I had the possibility to compare naim uniti atom + focal vestia no 1 and now I have naim ci uniti 102 + buchardt P300.

I prefer the current combination when it comes to sound and stability, even though I still have to wait a few hundreds hours for my speakers and cables to reach maximum potential.

You won't be disappointed if you like simplicity and stability.

PS: I found the golden legs on a website, for a good price and thanks for this idea, they look really nice together.

Great review betzea! I'm testing out a Yamaha RN1000A right now. The Yamaha and Naim are very close as far as detail with my Dali floor speakers. Both the Yamaha and NAIM have a cool-ISH feel to their sound signature. I feel the Yamaha is a tad more hallow than the Naim. The Naim with my current speakers/room acoustics feels bigger, and they could be due to the class D topology, or gain setting of the Naim.

I feel that both these amps really pluck out the detail. Both really engaging. I wouldn't consider them bright, or overly forward. I also auditioned a Marantz 40n that was returned (long story, but ask if you're thinking of buying the Marantz 40n) which was buttery, buttery smooth. Very noticeable difference in warmth and coloration of the sound. The Marantz did not work with my Dali's though. The Dali's are laid back enough so pairing that with a laid back amp produced a overly laid back sound. The mid bass was too prominent, even with adjusting the tone controls (bass turned down to zero). I messed around with speaker placement, but I'm limited with how much I can actually move the speakers and WAF.

I felt the Marantz lacked detail for my setup but if you have neutral or bright speakers I feel it could be a killer combo. As I grow into this hobby, I'm learning that I prefer more detail, than an amp that is overly warm. The warmth gets boring for me, even though for some artists works really well. I find that if I'm having a cocktail and listening to music for enjoyment I like the Marantz but if I'm listening to a new album, or listening for analytical experience, I want a more critical amp. Maybe in the future I will have a bigger space, and budget to have several amps and speakers to go with my mood.
 
Hi. I asked Amirm and asked him if he could test the Naim. I talked to him to find anybody which could send him a unit. Is anybody able to send Amirm a Unit?

Best regards Stefan

PS: I'm already a owner of the naim supernait
