I work in a professional studio, and we don't just use any cable. There is a big difference, and this goes for your home hifi as well. Many people just don't have the ears or equipment to hear the difference. I can, and its not a placebo. I have had speaker cables sound boomy, lacking bass or being too shrill in the top end. Making a/b tests on the same day showed an obvious difference, making it possible to find the right cable for my system and listening preferences. I must add though, that I find it easier to hear the difference with analogue cables, digital, I am not sure I can.NO, it’s the other way round, only audiophiles believe the cable manufactures hype, and mistake placebo effect as a factual difference, the rest of the world (Including musical professionals that use equipment that makes even high end HI-Fi sound mundane) deals in fact, however if you can provide independent verifiable evidence that they make a difference, then I look forward to the link, otherwise it would be better to say that it is your belief that they make a difference and not parade it as fact, when you review cables. (Trust is hard to gain but easily lost)
I was as sceptical as the next man, about cables making any difference whatsoever - speaker cables in particular. But then, back in the late 90s I swapped the hardware-store cables I used (10m for €5 in today's money) with the entry-level Monster Cable (can't remember the model name but it was praised but WHF), and the results where shocking. And I'm talking budget hifi here; Rotel RA-02 with Tannoy Mercury M1. Mids came to life, and the low-end tightened up. So yes, the (loudspeaker)cables can - and do make a difference. ♫♪As I said I do think analogue cables can sound different. However sometimes different is not better. Monster cables for instance have gone virtually bust because it was made clear that they sold overpriced cables that made no difference ....hifi magazines claimed they did and regularly reviewed as such. Obviously sold advertising space. So I think what hifi and other reviewers have a duty to make it clear they prefer the sound of the cable and not blindly say "it is better" I just wish they would take blind tests without knowing price ,brand, of item that would be more realistic and accurate. Anyone would be influenced by knowing price or brand first.
