I know this sounds outrageous, but I purchased a set of these cables on faith and some study for my speakers. I have the Apogee Scintillas One Ohm, Krell KSA-80B and NDX Naim Streamer--soon to be replaced by an ND555. I also have the reference interconnects. They really brought my system to life and gave me the sound I was looking for. I had just regular cables before, but was looking to get a certain natural sound, duplicating what live music sounds like to me. They do that. I have no regrets. Can't wait for the ND555/PS555.
PS: I am the founder of Apogee and the designer of these speakers as well as the Full Range Ribbons, so have some background on what they should sound like. They have never sounded better.
