I played flute and piano. I KNOW when a component changes - as in dilutes, or changes - the tonal quality of those two instruments. Needless to say, I don’t agree with MANY of these posts. And NEVER HAVE. I’ll trust a musician’s hearing more than many commenters on here who wouldn’t know a flute from a piccolo from a clarinet. I don’t think of myself as a musician, but I hear symphonic music regularly and I still pick up the flute from time to time at home. And I have always made it a point to have dedicated outlets, as far back as 1985. I can hear the difference. Oh, and outlets, too. I wonder how many people have really done their homework, which means TRYING IT in a system with correctly applied acoustic treatment in their listening room. Not the dealers. THEIRS. I have a dear friend who minored in music (and knows it MUCH better than me). I’ve sent him Shunyata power cords and interconnects and speaker cable that I owned and asked him his thoughts. He lives in an apartment complex. I put his system together many years ago, and I’ve heard it periodically when I return to California. He picks up the changes without the slightest prompting from me. He’ll refer to a specific recording we both have, and he’ll know EXACTLY what he hears in the composer’s writing with Cable A, Cable B and Cable C. And he hears precisely what I do
Too many people don’t play instruments, don’t attend symphonies (or any other concerts of acoustic instruments). To be blunt, I don’t give a damn what they ’believe.’ "Belief" is not the same as ’experience.’ And a dealer’s showroom is a poor substitute for my listening room. (Some of them don’t know music, either!) And measurements won't tell you if you're playing a Yamaha flute or a Gemeinhardt flute. Many components are still not tonally satisfying, no matter how well they 'measure.'
I’ve had ASC Tube Traps since 1988 (courtesy of J. Gordon Holt, who wrote the first review of them I ever saw). Measuring a room before and after Tube Traps installation is eye-opening. And the Iso Wall Damp is equally effective. But if someone says they have no acoustic treatment in their listening space - and never have - you might want to take their advice with quite a few grains of salt.
I know Karen Sumner of Transparent plays cello (or did). She’s been playing it for 50 or more years. Some designers don’t play instruments or don’t attend symphonic concerts much. But Transparent cables have the correct tonal quality (as did MIT cables before Karen stopped distributing for them in the ’90s).
The cables DO make a difference. But WHERE they make the most difference? You need to do the work yourself and put them in each position, give it a week, then remove the cable and see where you get the most impact.
