Do cables makes a difference? Yes they do. I am not an expert, but I have a pretty good system. I have used cables that range in price from merely expensive to ludicrous. I have used networked and non networked cables. They all sound different. For sure example, I had Nordost Heimdall 2 cables, they were good, but I felt that they lacked a full range sound, simply put, I could do better. I moved to pricey MIT cables and the sound was exceptional. The bass was improved, the highs were better namely, the whole experience was vastly improved. When I upgraded my amplifier I had to change cables.... not because of of sound, but because of synergy. I went with cables that were less expensive but I found to be even more revealing. So did cables matter? Yes. Do they have more fidelity, I’m not sure. The mit cables were more detailed and provided more bass. Was the bass more faithful? I do not know. When I changed cables, I had to use a spare pair and Theisen cables had good highs but sounded veiled and lacked bass. The replacement cables did not have as much “bass” but I felt that they were even more revealing and detailed. Better? That is an opinion of one. Do they sound different? Yes!
