I am not prepared to concede, as quite a number here have posited, that exflute's ears are good for playing in a professional orchestra but bad for hearing cable differences.
I just can’t — it’s like trying to reason with a bag of hammers.
Cable curmudgeon
I'm not an 'audiophile" but I like to think I have a good ear having been a professional musician (principal wind player in major symphony orchestras) for 50 years. A number of years ago going into an excellent audio equipment store I talked with, what seemed, a knowledgeable salesman. Being a musician experienced in audio systems but not expert on all the equipment out there I had some questions concerning high (over-priced?) end cables. The salesman assured there was an audible differencet in a demo room switching back and forth etc. After a few minutes I noticed the sound coming out of only one channel. He complemented me on my "good ear." Hmmm? A few years later when setting up my home system I investigated speaker cables. Two sets of Monster, stranded standard cable, solid core copper (used for alarm system) attached with like connecters. There was a difference. However, not in terms of better or worse: bass and treble were acceptable as was clarity loud and soft. Differences were esthetic- like asking "whose the best tenor" (I like Plácido). Now I know as a musician used to live (i.e. un-amplified) music that all I hear coming out of a loud speaker is perforce ersatz. But most everything today comes out of a loud speaker whether a rock concert or a hi-fi system so perhaps my opinion is curmudgeonly. But, for me, spending oodles of money on hyped cables, well... I liked the solid core for my alarm system- still do.
