"Usually good engineers would have a technical hypothesis that can be measured.If we are talking about sound engineers (not EEs or whatever) simply selecting new cables because "they sounded better to us" then that’s just the same anecdotal evidence that any other audiophile uses to select cables. And anyone is susceptible to bias effects. " (1) Given that there IS NO metric given, by current science, OR any electrical engineering standard, by which we can MEASURE what exactly results in a wider, deeper sound stage, the natural bloom of instruments, more detailed/realistic/cleaner highs with less stridency(at the same time), allows for more separation between voices(better imaging) and/or whatever else, those of us that hear those improvements appreciate AND (2) given that the owners of the studios that have proven track records, of putting out superior sounding products to my, as well as many other’s ears(judging by their clientele and rewards), obviously agree that better cables matter: I’ll stick with OUR, "biases". (WHEW- How’s that for a run-on sentence?) My ears have served me faithfully(even saved my life in a couple scenarios), as well as made many customers and musicians very happy, over the past few decades and I trust them. ’Nuff said, and I don’t expect all those keystrokes changed anyone’s opinion anyway, so I won’t waste any more on this thread(was that an, "AMEN", I heard?). ps: As mentioned, it doesn’t have to be expensive!
