Naim Audio system owners - What speakers are you using with Naim?

In my main reference setup I’m using the Magico M6 paired with the Naim Statement NAP S1 monoblock amps & Naim Statement NAC S1 linestage analog preamp. They sounded fabulous together.

In my bedroom setup I have the Naim Uniti Nova paired with a pair of PMC standmount speakers. Match made in heaven. Prior to the PMC, I had the Naim Uniti Nova paired with the B&W 805 D3 standmount and the Sonus Faber Olympica l standmount speakers and they sounded fantastic together too. Out of these 3 different sets of speakers paired with the Naim Uniti Nova, the PMC have the best synergy with the Uniti Nova, then followed by the B&W 805 D3, then lastly the Sonus Faber Olympica l standmount. 

In general, Naim electronics will pair well with PMC, Harbeth, Spendor, Magico, B&W among others. What kind of Naim electronics do you have? I’m a big fan of Naim.

FYI, Naim has its own community forum and I suggest you join the Naim forum at Naim.co.uk.

PMC & Focal speakers will have best synergy with Naim electronics. 
Ever since Focal acquired Naim, Focal has been voicing and tuning their speakers using Naim electronics. B&W will pair well with Naim too. 

Naim also makes awesome musical sounding streamer/DAC. I'm sure you are aware that you will have to use DIN connections to connect between Naim components in order to achieve best sound. Don't use RCA connections. That's why you will have to go all the way Naim, starting from their streamer/DAC, preamp & power amp and make use of their DIN connections to connect between them. No other hifi manufacturers make use of DIN connections as far as I know Naim is probably the only manufacturer that does that. DIN is pretty much like Naim's version of XLR balanced analog connection. However the Naim Statement NAC S1 preamp & Statement NAP S1 monoblock amps provide DIN, XLR balanced & RCA connections. 

Naim amps power output ratings have always been conservatively rated and while their power output ratings (wattage) are usually low but their power and current delivery are very robust and are capable and have no problem of driving difficult speaker loads and are stable down to low impedance loads. 
Current delivery that matters and is more important than the power output ratings (wattage). And I will guarantee you that say a power output ratings of 100 wpc @ 8 ohms off Naim amp will be very different than the same power output ratings of the same 100 wpc @ 8 ohms off an AV receiver or some cheap integrated amps or some cheap power amps. 

Dynaudio too.

I've heard the Naim Statement preamp & monoblock amps paired with the Focal Utopia Grande Evo iii at last year RMAF (Rocky Mountain Audio Fest) with Naim ND 555 streamer/DAC + 555 PS DR power supply unit served as digital front end source component and did not sound bright at all. 

I myself own a Naim Statement NAC S1 linestage preamp and Naim Statement NAP S1 monoblock amps driving my Magico M6 speakers and the overall tonality is on the warmer side of neutral but I would characterize it as intoxicated warmth, nothing like tubey syrupy liquidy type of warmth. I know I have different speakers (Magico M6) not the Focal Utopia Stella like the one you have.
My front end source components are also slightly on the warmer side as well. My analog front end source components : Clearaudio Statement v2 turntable w/ Statement TT-1 tonearm, Statement Goldfinger cartridge and D'Agostino Momentum phonostage pre. My digital front end source components : MSB Select ll DAC w/ upgraded Femto 33 clock & two mono powerbases (two separate mono power supply units). And all my cablings are slightly on the warmer side of neutral. I'm using Transparent Magnum Opus cablings. 

That's what I like about Naim electronics they sounded very natural musical smooth with a touch of warmth (intoxicated warmth) punchy full rhythmic sound. They excel really well in PRAT yet maintain its relaxed quality without sounding strain or anything. Music simply blossoms to the fullest with all Naim electronics in the system. 

You should actively get on Naim UK based own forum community. I am as well. I'm always on Naim's own community forum (UK based). Not everyone here on Agon love Naim and some here think that Naim isn't for music lovers. I remembered seeing that kind of comment here before (I think he knows what I'm talking about) and people like him had no idea what they are up to.
Naim is nothing but for music lovers or music enthusiasts.
