I made a few of these cables at 2m length (x4 for biwire) and after the time I put in, I was expecting a lot better than the Silver Anniversary I was using , and the Twin and Earth which I had also tried. However I was not too impressed when the volume was higher it seemed a little strange sounding, hard to describe it just didnt sound right. I have since found out that another method of biwiring was to take one of the three cables and split this for the tweeter and then combine the other two cables (colour for positive, white for negative) for the woofer. This did sound better but still wasnt the great sound that I was expecting. Since then I have bought the 4 core 2.5mm Van Damme Professional Loudspeaker cable from Maplins at about £3 per metre. This cable looks great and is very flexible and easy to work with and I have found out since is used for a lot of professional installations. This cable sounds great compared to all others I have used QED SA, Atlas 2.1.1, CAT5 and Tand E and is an excellent choice for those of us who cant afford hifi equipment the cost of a good second hand car.
