Supra is very good for the money. I have their power cord which I didn’t care for their ends as they feel very cheap so off they went. The Supra PC to my ears a little soft or not as open and revealing as my Wywires and Nordost. I also purchased the Supra Power Block and again very good for the money, although not up to my PS Audio P5. Lastly I use a Supra Ethernet cable to my Bluesound Vault 2 which I prefer over the cable that came with it. Haven’t tried other Ethernet cables but very happy with the Supra.
