The new PINK Fuse infuses your music with realistic warmth, added resolution and dynamics, plus the lowest noise floor ever. Designed as a totally new generation fuse that maintains the Purple Fuse’s musical warmth but with added resolution and dynamics, combined with enhanced musicality without sounding artificially warm or coloured, with, or without, Master... Founded in Japan in 2013 DS Audio have introduced a radical new cartridge design which does away with magnets and coils! In contrast to moving-magnet (MM) and moving-coil (MC) cartridges, which work on the principle of electromagnetic induction, the DS-W1 uses an optical system to convert stylus/cantilever movements into audio signals. The advantage of this system is that it completely eliminates the electromagnetic frictional force that is a ‘fact of life’ in all MM and MC designs.

I remember as a teenager getting my first few meters of QED 79-strand cable and being fixated by how they could put 79 strands into a single cable and make it so thick. Back then we never thought anything about connecting our awful thin-wired mains leads into the backs of the HiFi (if it didn’t already have a lead coming out of it). Roll on 40+ years and MRCU has brought out two chunksome cables into the world that would have turned heads and minds back in the late 70’s. These are ginormous cables in comparison with my old QED, arriving as they did in a large box with bubble-wrap. Of course, their size is there for a reason, not just for looks. Some people are very open about what is inside their cables, but some are not quite so forthcoming, which is a shame as I can’t tell you much about the conductors or materials for...

Meet David Brook, from MCRU, a company that not only sells products from major brands but also produces an amazing assortment of their own, like the speaker cable and mains lead up for review... Indeed, they even offer some of their mains leads for you to terminate yourself, keeping the cost down, though all products are very competitively priced. I’m always impressed by David’s knowledge and enthusiasm, but he understandably doesn’t want others to know all about the magic inside the sheaths. His own products are very unique and many are great looking, especially the Ultimate MkIII speaker cable coming in at £600/3-metres. If size really matters then this very thick monster of a cable should get excellent marks. Similarly, “The First” Mains Power Lead mains lead is equally impressive in looks, and I was keen to connect these up at the earliest opportunity.

MCRU is based in Elland, just south of Halifax, up in West Yorkshire, and a few minutes from the M62. David has spent most of his life as an audiophile and music lover, and having an obsession with cables, setting up Mains Cables are Us, before changing its name to MCRU. As well as many cables from a number of big brands he also stocks HiFi, having two top systems on demonstration. Since little is known about these cables outside the minds of David, my life was made slightly easier as all I had to do was listen and write. “The First” Mains Power Lead is aptly named, as this cable is designed to be the very first thing your HiFi should see, ideally placed before a mains conditioner or at least the mains... Luckily for me, my house is festooned in mains conditioners, having advised a number of companies on designing conditioners and mains cables, plus being the proud owner of a good Isotek.

The First is made using a cryogenically treated cable with 5.5mm2 conductors and an active copper earthing screen shrouded in a carbon-infused polyester sleeving as the final shield to combat RFI. This cable is certainly beefy, and not easy to sit behind the HiFi, and certainly not coiled up out of sight. This one needs (and insists) that it is seen by everyone. Be warned, if your mains socket is near floor level you will have difficulty plugging it in as the cable doesn’t bend as easily as many mains cables do, and the Furutech FI 1363... This excellently connected lead comes in a choice of three terminations (produced by Furutech) and different fuse choices (SR or Hifi Tuning fuse). My unit arrived in a massive box with FL-UK-NI (FI 1363) mains plug and FI-11 (CU) IEC socket (this is high-grade pure copper deep cryogenically treated) and with HiFi Tuning fuse.

Audiophile cable suppliers and manufacturers are two a penny, so when the time comes to add or replace an existing cable, customers are faced with a plethora of options. This can leave them confused and can lead to the purchase of a product that takes their system’s balance down a less optimal than path. This is where a dealer who understands your system is invaluable and can end up saving customers money in the long run. MCRU is among a select few companies that are both dealers and manufacturers. Not only do they stock cables and products from some of The Ear’s most coveted brands, but they also manufacture a range to complement products from the established product lines they offer. This, in many cases, brings customers better value as they are cutting out distribution and marketing costs.

MCRU, for those new to the brand, stands for Mains Cables Are Us – see what they did there. The company was started by Yorkshireman David Brook and his wife Joanne in 2008. From humble beginnings as a producer of, you guessed it, mains cables and distribution blocks, MCRU has become one of the UK’s leading suppliers of all kinds of cables and mains products for hi-fi,... Bricks and mortar, Brook Audio serves as a traditional hi-fi dealer, with comprehensive demonstration facilities, but also acts as a distributor for a number of boutique high-end audio manufacturers. I will first talk about the No. 71 Mk2 analogue RCA interconnect, the 1m long review sample retails at £525.

So a popular price-point and one that includes strong competition from the likes of Chord Co and Tellurium Q, to name but two. My sample of this cable was built by MCRU’s master technician, Mike Brunskill, and there are certainly no complaints from me regarding its construction. The RCA connectors are Australian brand ETI Research’s top-of-the-range Coda plugs, which alone retail for £149 per pair. These plugs are an upgrade upon the brand’s popular Silver Link model, which has quite a following. Close inspection reveals plastic plug grip inserts, which are used to minimise RFI/EMI noise. Mike Brunskill explained that minimising the amount of metal used in a plug gives the added benefit of reducing resistance.

In an effort to reduce bulk as much as possible, the wall of these plugs is just 0.6mm thick. Designed by Nick Gorham of Longdog Audio, the very first power supply we sold was for the Squeezebox Touch, after one was sent to HiFi Choice magazine the reviewer Patrick Cleasby (ex BBC employee)... 100’s sold since and one thing is constant, the MCRU linear power supply improves the sound quality of anything connected to it. Proven by 100’s of satisfied customers and positive feedbacks. If you have not yet experienced what our power supplies do then please get in touch, if your equipment is powered by the dreaded “wall wart” switch mode power supply then up-grading to a...
