OK, so I know you’re all going to think I’m mad, or an idiot, or possibly both, but I’ve finally managed to get my SuperUniti to work properly for the first time in 9 years.
Some background: I bought my SuperUniti new back in 2013 to replace a Planar 3 / Denon CD Player / A&R A60 / Heybrook HB2 system that I’d owned since my school days in the early 80s. I assumed the SuperUniti would be a massive step up – it wasn’t, it was a massive disappointment.
Which was odd, because it had sounded pretty great in the shop.
The Heybrooks made way for B&W PM1s, but it still didn’t sound right.
They eventually made way for Dynaudio Special 40s. Still not much better.
The sound was small, thin, hard and lacked air and kick.
I took it back to the dealer – and we listened together in the shop – sounded great. In fact (as it had been run in by now) it sounded better than his demo SuperUniti.
But at home it still sounded awful.
Now… I knew that Naim kit of old had been fussy about speaker cable, but I’d been led to believe that the new stuff didn’t really mind what cable you used. I knew that Naim recommended NACA5, which was probably loose change to someone with a full separates system, but for a SuperUniti it seemed expensive overkill. As it turned out, my Naim dealer agreed with me and supplied me with some basic 2.5mm copper core cable – looked a bit like QED 79 – not sure it was though.
Still didn’t sound great. Over the years I fiddled with different NASs, routers, mains, but nothing really improved.
Recently, out of frustration I tried taking my SU over to a friend to try it in comparison to his Atom. It sounded great.
Back home, it didn’t.
Then I took it to another friend and it sounded great there too, through his modest Yamaha floor standers. So I went and got my Dynaudios and… it sounded terrible.
It turned out that my friend’s speakers were bi-wired so I couldn’t use the same cables to the Dynaudios – so I had taken mine over.
Then a thought hit me.
My friend had some boggo Kabel Direkt cables in his second system – which I asked to borrow. Brought them back to my place and plugged everything back together…
Bingo! The lights finally came on.
His Kabel Direckt cables were cheap, but they were 4mm copper instead of 2.5mm. (I note that NACA5 is also 4mm).
The SuperUniti into the Dynaudio Special 40s has completely transformed. It’s so open and effortless at any volume. Airy, open and detailed at the top, punchy and tight at the bottom. Even Spotify sounds amazing.
This is what I’ve been missing all these years.
Now I finally get why everyone loves Naim.
I feel foolish, but also rather annoyed – after all it was a Naim dealer that gave me the offending cable in the first place.
However, it sounds great now and that is making me very happy.
I write here, just in case anyone else is struggling with a hard, thin, weak sounding Naim Uniti – if you are, it just might be because you’ve been led to believe that it doesn’t need fancy speaker cable.
Actually, it DOESN’T need fancy speaker cable – but it DOES seem to need something that’s 4mm copper.
I really cannot believe how good it sounds now. Just a shame it’s 9 years late.
