Further Information

LFD Audio Grain Free Signature 3m Bi-Wire Speaker Cables.

Bananas at both ends.

Excellent Used Condition. I also have matched custom LFD Audio cables built for Tannoy SuperTweeters in a different listing.

These cables were a custom order through Howard Popeck of LFD4U prior to his retirement. They were used between my Convergent Audio Technology mono blocks and Tannoy Canterbury Speakers. They were also built with a ground wire to connect the ground connector of the Tannoy speakers to the ground connector on the amplifier.

These a true bi-wire cables with 4 connectors: 2 copper connectors for low frequencies and two silver connectors for high frequencies. Dr Bews, the founder of LFD Audio, made the following comments about this cable: 

" ... LFD Grainfree biwire is a biwire cable only, since it uses different conductors for bass and tweeter, i.e. multi-strand Grainfree copper for bass and solid core Grainfree conductor for tweeter. This is the most popular LFD loudspeaker cable since it has a full bass with a warm mid and controlled top. 

This cable is very good and the Signature version uses a Grainfree silver conductor instead of copper for the tweeter conductor. 

The Signature version is reference standard regarding sound quality despite being relatively cheap. The Grainfree biwire cables are VERY good choice for solid-state equipment ..."

LFD Audio is a boutique UK audio manufacturer formed in 1987. Dr Richard Bews, the founder of the company,  is a direct PhD student of Professor Hawksford who formed an audio group which carried research into audio design which MSC's and PhD's were awarded. This was run at University of Essex. LFD was started in 87' by Dr Bews and Professor Hawksford . Dr Bews has much admiration for Be Yamamura who Richard sees as a mentor. From this Richard acquired a passion for creative High End audio, utilising unusual and obsolete parts. The first product was the truly legendary Battery disc stage which is unique and innovative and ultra simple which demanded only the very best parts and wiring including bakelite pure silver leaved capacitors and shinko tantalum film resistors. It was a test bench to evaluate parts wiring and layout. This is a completely floating battery powered design .

With respect to cables; Richard's view is most equipment is limited by the external and internal cables and to improve LFD amplifiers, heavy amounts of research has gone into cables, basically for the R&D of the Multi diameter cables, more than 2 Million US Dollars was invested to produce various diameters and profiles of conductors using a continuous cast processes.

There is very little information about LFD Audio. They don't even have a working website. Most of their sales are through word of mouth. Information can be found on Audio Forums such as What's Best Forum.
