I used to have Kimber 8TC speaker cable which I thought was good. Then I replaced them with Nordost Blue heaven cables and the improvement was immediately noticeable. Then I had a chance to buy Nordost Tyr 2 cables at a great price. I cannot say that I noticed any improvement but then I don’t have golden ears and cannot distinguish the nuances as reviewers describe with all kinds of fancy adjectives. Same with interconnects. I started with Synergistic Foundation silver cables (less than $700) and they sounded fine, better than the Kimber Heroes they replaced. Then I “upgraded” with their Galileo SX interconnects, used at a good price, but couldn’t notice any improvement. The lesson learned is that for my particular system and my hearing, get a good cable from a well known manufacturer within your budget and stay with them. It’s an individual thing and I won’t be buying Crystal Cable or Siltech.
