The original No.91 is one of our most popular power cables, made using the legendary Belden 83803 cable with foil shielding and active ground loop system to shield and screen the cable and prevent RFI pick up, the cable is well proven in audiophile circles and has been known to out perform cables costing double or more.

The No.91 SE version uses the new Furutech FI-1363 in line mains plug in pure copper version, specially commissioned by MCRU from Furutech of Japan, not available anywhere else. Furutech’s build quality is second to none and performance wise is up there with the very best plugs available at any price. 

The No.91 SE sets a new standard in performance to price ratio as we have been able to construct it with our own bespoke internal filtering system inside the plug and IEC connector and in turn it offers performance which belies the low price. The IEC connector and mains plug are both copper, cryo treated by Furutech using their own patented Alpha process.

1 metre long as standard, extra lengths available on request.  


I am not one of those people who thinks that changing audio cables will make a huge improvement to their hi-fi set up. I’m in the “Emperor’s New Clothes” camp on this one. But, on the other hand, I can tell when I have a technical problem that needs attention.

My headphone amp was suffering some little annoying plops, hisses and growls. I had recently cleaned the mains and knew that that was not causing the trouble. But it’s so easy to be confident as well as WRONG. The mains were fine – all except for the final metre, from the plug to the amp’s own connector! The noise was what?  EMF? Induction? Stray RF signals? Who knows? Maybe all of them to some extent. To eliminate, I could either track down each one of them …. or …. simply stop them from infecting my system. Now that last choice seemed like a great deal less work.

Browsing the internet, Mains Cables R Us No.91 caught my eye. It mentioned ‘Faraday Cage’. I remember those. I thought never mind when the thing was invented, this is going to be the future! And it is. All that annoying noise has gone! But in it’s place is something else, something I didn’t expect; an improved sound! The bass lines are cleaner and deeper, the highs just float away ….. the sound stage had always given the instruments their own, clearly defined space. Now, it was almost like you could hear that space. Sounds silly, I know. Listen to me “hear that space”. As if! 

It was sort of like cleaning your glasses, or flicking your windscreen wiper on a foggy day. Suddenly, a clearer picture emerges even though you hadn’t realized it was hazy before. Some thing good has really happened! I can’t say what, but remember, I’m one who can’t even see “The Emperor’s New Clothes”.

Drawbacks? Well, it’s red. Not a problem for me but it may be for you. Also, the cable doesn’t bend easily. The coil in the picture is the sort of size the installed, coiled cable is going to be in your system. My, but how, well it works! Maybe I’m not the only one who can’t afford a £200 – £300 mains cables. Don’t worry, you couldn’t get anything better than Mains Cables R Us No.91 in this price range. It’s a bargain.
