BJ Cable sells good quality cable with good terminations. I own a few pairs.
The owner's philosophy is that cables make no difference in the sound whatsoever. His prices are fair, but his products are not amazing for that reason.
I think what the owner means is that his cables are neutral and do not add any coloration to the sound. I asked him for advice a while back regarding Canare vs. Belden cable and he replied with a lengthy email detailing the physics of how a cable is made and carries current between components. He said that neither brand would influence the sound in a system, and then added that some manufacturers sell cables to be used as tone controls and that this is the wrong approach.
It was not the answer to my question, but I think his point was that his cables provided a neutral pathway and did not add coloration to the sound of the original source material.
I agree with Runnin that with higher end gear, cable choice can provide different sonic benefits within a system.
I am not dissing Blue Jeans in any way; they provide a good bang for the buck.
