Ok. As per my most recent post I just finished up a blind A-B test with the two sets of cables I own. I recruited a friend to switch them in and out while I was out of the room. He covered them with a light cloth and called me back in. We played some Keith Jarrett Trio lps and cds plus some wonderful Bobby Watson (jazz sax) discs, the latest (2018) version of The Beatles White Album, a terrific 200 gram lp of Muddy Waters "Folk Singer" and assorted other tracks. It was immediately apparent which speaker cable was which. The cables were the Cardas Clear Cygnus vs a one-off label that touted itself as a "silver reference." The treble was more edgy and the whole presentation was less focused with the one-off. With the Cardas the sound was more smooth/less fatiguing. Plus the music tended to emerge out a black background. Clearly there was a far greater sense of depth and sound stage with the Cardas. My friend tried to trick me multiple times by leaving the cables un-changed from one trial to the next as well as switching them up. The process did take a little time and cost me a six-pack of good micro-brew IPA but was worth it. We did adjust the speaker placement, too, to see what changes that wrought. Prof1 and countless others are right about the importance of room placement. I note that the two times I've been to audio shows and saw how fussy Jeff Joseph was about placement has long caught my attention. Just thought I'd pass this along. I must add that I greatly value Prof1's detailed and thoughtful critiques as they have helped raise my consciousness about how music sounds through different transducers. It's just that to my ears thru my Joseph Profiles I could readily detect the difference between the two cables I own.
