Hi everyone, I'm a proud owner of a new copper Kimber Axios cable that pairs when my Focal Stellias. Love the boxing, build quality and overall experience of using these cables. I have never seen cables braided so beautifully and they are a joy to look at and to hold. But (and I hope this doesn't ruffle any feathers), I'm not entirely sure I can detect an audible difference with using these cables. I should preface this by saying that I don't think I have particularly "golden ears". I can barely discern the difference between many DACs and after adjusting for volume and power, even between amps of equivalent quality. If I train myself to listen, in a quiet listening environment and with concentration, I can discern subtle differences IF I know what to look for and this is rewarding for me. For everyday listening, even if I am not paying 100% attention and listening critically, it's nice to know that those subtle details are there if I were to look for them. My question is for high end cables (going from stock cables that are already of pretty decent quality), what should I be listening for?
