CnoEvil is right in that the polarised camps on cables are both correct, IMO.When I started on my hifi journey I had a Nad CD and amp and some very nice Schonberg speakers. The guy who owns the shop wanted then to demonstrate how cables change the sound. After a short test we both agreed it didn’t. As I upgraded I found that interconnects made a material difference, but less so speaker cable. Then things got interesting and led to one of those aha moments.My sound room is a converted garage and my speakers were facing the shortest distance across the room. At the time I had a MF M6i amp with the DALI 800 Mk2 speakers and Nad CDP. I wanted to hear the chord Blue DAC and compare the upgrade with a MF M6 pre and power amp combination. (to see what would give me the biggest sound improvement, if you get my jist)I was disappointed neither offered any significant change in sound quality. So a £350 CDP was competing with a £4500 CD transport and at best it was very limited. At this time I was beginning to subscribe to the CD transports are nothing but dots and dashes and the law of diminishing returns had reached a point of singularity. I changed the position of my speakers which are now facing the long side of the room; I have a greater distance between me and my speakers. WOW, the change was immense. So I went back to the previous test, the chord Blue being first then a pre and power amp. The chord blue sounded unbelievable a far cry from my first test that said I took a gamble and bought a DCS Verdi – it paid off. The ‘ its only dots and dashes argument ‘ was crushed for ever. So was streaming as comparison. I also changed my amps to AUDIA 100 pre and power amps again the change is massive. So the moral ( for me) of this story is – sound upgrades depend on many factors. And to hear an upgrade in sound whether it be from cables or from separates the system and listening environment must be have the capability to allow for any upgrade in sound. More to the point most cables won’t make a jot of difference to low end stuff . So for many people cables won’t make any difference for some they do. Which I think makes me a Blue. I get the logic to both arguments but music is an emotive thing. So CnoEvil was right both views are true. And the one thing we can all agree on is trust your own ears the answer lies there.
