$1500 per cable gets you midfi cables. You a are better off putting that money into a 4500 pair of speaker cables.
better value for money are the 500-650 dollar power cables from Synergistic research foundation and they beat AQ an Nordost. Nordost make good cabels only after 10-30k! You don’t need to spend more than that and won’t get better sound. Most good power cables start at about 3500-5k before they really improve things enough to justify their price. Kubala sosna reailization is in that range then Synergistic Research Galileo and SRX level after that from 6-8k!
Shunyata is meh compared to KS and SR.
Ansuz makes great power cables as well try the X2 in your price range. Ansuz is an evolution of Nordost and all of their cables beat everything Nordost has in their price range.
