Townshend F1 Fractal loudspeaker cable

Townshend F1 Fractal loudspeaker cable

Max Townshend has been an interesting and highly creative force on the British and International audio scene for the past 43 years, making huge contributions in many areas. Examples include The Rock turntable with its floating stabilising paddle, supertweeters, and the Allegri preamp — the closest thing to a straight wire with gain. For the last 30 years, however, Townshend has increasingly focused on the role of vibration in audio, designing a family of Seismic Isolation products, to dampen unwanted isolation from the hi-fi system. While a relatively modest operation, Townshend is a mighty David to the industry’s Goliath!

Cable manufacturers tend to divide up into two sorts. There are those who listen to a vast number of cables, make their selection and market existing cables dressed up in artful sleeves. Then there are those who approach cable design from the ground upwards, using first principles and innovation. Townshend falls into category number two.

If I may be permitted to expound some of the thinking behind the design of the cables; the amplifier has effectively zero output impedance and the speaker load is mainly resistive with a nominal 8 ohm speaker having about 6.5 ohms resistance and the remainder reactive, comprising inductance and capacitance. Any speaker cable also has inductance, capacitance, as well as a small resistance. The value of inductance and capacitance is determined by the geometry of the cable, so the wider the spacing, the higher the inductance and the lower the capacitance and vice-versa. The optimum relationship between inductance and capacitance, as determined by computer modelling, for lowest distortion caused by reflections in the cable, is derived mathematically by making the ratio of inducance divided by capacitance equal to the resistance impedance of the speaker squared. 

To achieve this correct ratio the cable must have a relatively high capacitance and low inductance. Townshend’s Isolda cable has used this design since 1980 to great acclaim using DCT treatment. (Townshend was the first UK adopter of this technology.) The new refinement is to use Fractal wire instead of DCT, a secret process that Townshend has developed. The two closely spaced, Fractally-treated pure copper strip conductors, which are now insulated with ultra thin PTFE, are encased in synthetic rubber and clamped within a strong, flexible conduit trimmed with woven polyester braid. The ends of the cable are terminated in a metal enclosure containing an RLC network to prevent unstable amplifiers from oscillating, to reduce distortion and to act as an RF filter; i.e., acting as an antenna. The cables, while flexible, look substantial. 

 

In general, I’m not a believer in cables. In my experience, they are like tone controls, so in a system where a part of the spectrum is over or under represented, a cable can make a subtle, but useful difference. However, the area where F1’s excel most, is rather surprisingly outside this category. 

The ability of a system to image well – that is, to provide a holographic soundstage – can often be down to the quality of the  mains, cables, and isolation. Without each of these areas being sorted, the system will only be as good as the weakest link, and consequently the effect of precision space generation will be weakened or lost.

Having spent a fair deal of time sorting out these issues on my review system, I was hugely impressed by what the F1’s seemed to be doing. 

Listening to the LSO recording of the Brahms 2nd Serenade, final movement [LSO Live], it was very clear that the F1’s were providing imaging not previously seen or heard on my system. The accuracy of the orchestra was eerily holographic, and seemed to roll out the orchestra in its front-to-back layers in a startling fashion. That’s not to say these cables are a one-trick pony, to paraphrase the colourful character on ‘The Apprentice’ a few years ago, they are a field full of ponies!

The bass is really tight, precisely formed, so the attack of the double bass section is absolutely clear, and keeps time very well. I am not aware of any colouration in the mid band or top, meaning the F1’s yield an airy sound packed with detail. 

Moving on to a recent Tidal streamed MQA recording of the Haydn Sinfonia Concertante, Rattle and the Berlin Philharmonic, this delightfully eccentric piece brings a smile to my face as the F1 cables work their magic. The delineation between the soloists and the orchestra is beautifully portrayed, the dialogues between the two groups seem to take on a clarity which adds to the humour of the piece. The fun these musicians are having is palpable. Opera for instruments! I’m also aware of a blacker noise-free background, the cables seem to be quieter than my experience of other cables.

These cables are most definitely expensive, but they come with a highly coherent concept to their design, manufactured from first principals upwards. The lack of reflection in the cables I think gives a clue to their greatest strengths, which is the ability accurately to portray lifelike 3D space in a way that I have rarely heard from a speaker cable. For anyone seeking to add this quality to their system, the F1 cables are required listening!

Russ Andrews RANS-1 Network Switch

The Russ Andrews RANS-1 approaches the network switch in a classic audiophile way; it separates the boxes into ‘gubbins’ and ‘power supply’, then uses higher-grade components in both to get the best possible performance out of the ‘gubbins’ part.

REVIEW

Rogers LS3/5A SE stand-mount loudspeakers

The LS3/5A is an iconic design. Change it at your peril. Rogers is a classic maker of LS3/5A loudspeakers, and they just modified the LS3/5A. The LS3/5A SE replaces the front baffle of the loudspeaker with a new material and improves the sound. Will there be pitchforks and torches ready to burn the heretics, or does it make a good speaker better, asks Alan Sircom.
