Cables

Filters, particularly AC mains filters and regenerators, have long been an audiophile staple but the genre has expanded in recent years to accommodate our embrace of digital and streaming audio in particular. With 'high speed' digital transmission comes the prospect of a sea of extraneous noise and interference, from both outside and inside the 'system loop', that washes though our equipment. Jitter in the digital domain and RF-related IM and other distortions are the least of what we understand as the audible consequences of this entirely unwanted hash.

Was it really 25 years ago that QED celebrated its Silver Anniversary with a special edition XT speaker cable? Or a full half century since the brand burst into our audiophile consciousness with, three years later, what must surely be the most famous cable of all time – QED 79-strand? Monster Cable would surely argue the toss, but for hi-fi fans building their first system on a budget, the classic figure-of-eight 79-strand (still only £1.99/m) has long been the go-to choice.

While audiophiles might ordinarily associate the 'home of the brave' with Linn Products, Scotland is also home to the hand-made Atlas Cables. Its new Arran interconnects and speaker cables are a clear evolution, taking inspiration from its solid silver Asimi range [HFN Dec '18], utilising the same geometry but with OCC (Ohno Continuous Casting) copper.

For over 40 years AudioQuest's founder and guiding light, William 'Bill' Low, has been on a journey of discovery, exploring the properties of different conductors, dielectrics and geometries to not only offer as transparent an 'analogue link' as possible but also isolate that link from an increasingly hostile RF/EMI-strewn environment. Bill also has a flair for the dramatic, invoking the spirit of the 'ThunderBird' in this entry-level Mythical Creature interconnect.

Cable aficionados will already know that the best insulation is no insulation at all, with air (in lieu of a vacuum) providing the best and most cost-effective dielectric. Did I say 'cost effective'? Kimber's new flagship 'Naked' interconnect costs a cool £12,700 per terminated metre – either with heavyweight gold-plated WBT RCAs or XLRs finished in a choice of Wenge or Purple Heart woods. For longer runs, 1.5m sets cost £15,150 or £17,600 for 2m. This is very 'high-end'.

Of all the true 'hi-fi accessories' power filters, conditioners and regenerators are arguably the most popular. (I do not count cables in this category because they are 'necessories' and your system will not function without them.) Cleaning-up your AC mains power has long proven its benefits, but what of the low voltage DC supplies – the so-called 'wall-warts' – that come packaged with so many of today's small form-factor DACs, headphone amps, phono stages and even turntables?

One of the founding fathers of the audiophile cable scene, California-based AudioQuest has been developing its conductor technology for no less than four decades. The William Tell Zero featured here is part of the 'Folk Hero' series – prices range from £2340 (2m pair), £2910 (3m) to £3480 for a 4m pair, with £570 per extra metre. This ranks as affordable when compared to the flagship 'Mythical Creatures' series that tops out at £20k for a 2m set of the Dragon Zero...
