Bi-wire conversion. Do you understand what is meant by Bi-wiring? And, what does Bi-wiring actually does? Because Bi-wiring is the best way to connect your loudspeakers.
Unfortunately, many people own loudspeakers (which are capable of accepting a Bi-wire cable) but sadly the loudspeakers are ignored. And, left with metal bridging plates installed. The current method is to remove the metal bridging plates and replace them with jumper cables. However, this method works well, but only to a certain extent. And, appears to lack the signal speed necessary to produce the optimum signal transfer correctly. This I found after many hours of testing with different lengths of cables. And, with different types of cables.
There are many different theories on this, which can easily be found online. And, one that certainly caught my eye was this. To achieve the correct sound, the cables should be of equal lengths. This will correct signal speed and give optimal performance. An interesting read. And, so is there a solution?
Standard Bi-wire conversion
After looking at the problem, it was easy to find a good working solution. And, I have called the solution the Bi-wire conversion. Two lengths of low-loss loudspeaker cable replaced the jumper cables. But, to achieve the best sound, cable length has to be same as the original. In practice, shorter cable lengths can be used because the overall performance differences are negligible
To improve performance, I used Aluminium foil. Aluminium foil provides better sound insulation and helps to eliminate many noise sources. And, the Aluminum foils ability to absorb sound allows unwanted noise to be picked up directly at the source. The Cables are wrapped with aluminium foil sheathing (which is first-line insulation). Followed by two levels ‘AirGap’isolation.
The cable provides a quick and easy way to convert a two-wire loudspeaker cable into a four-wire Bi-wire cable. And, results are easily heard and your system has reached a new level of performance. The Bi-wire conversion can be made to any length you require. But, a thirty-five-centimetre length works very well and becomes cost-effective.

Reference Bi-wire conversion
The reference version is the result of six months of hard work and aimed at the serious audiophile. The cables offer exceptional performance and the difference heard after the first three seconds!
The construction has reached a new level. Firstly, the use of two internal conductors (2.5 mm2) with full shielding from top to bottom. Also, the conductors are helical wound, which increases the cable length from 1 to 1.2 – giving more air and space in the musical presentation. The cables used are from the reference series. High purity OFC with either NextGen (24K gold plated) or Rhodium (Twin screw) Banana connections.
What you are doing is simply turning a single speaker cable into a double speaker cable. And, by doing this, you have eliminated the standard ‘bridging plates’ or the supplied ‘jumper’ cables. By using the Reference Bi-wire conversion 440 mm length of cables you are now opening up a new experience.
I have spent months working with this project and final testing was done by one of the leading Audiophiles in the Baltic countries. And, I will be forever grateful for his help and time in allowing me to use his facilities.
