I believe measurements can be useful in making buying decisions but they certainly don’t dictate what I do. Ive bought higher-end cables, etc. that the objectivist would scoff at. With that said, this is not a one-way street. I have read quite a few vicious personal attacks made against objectivists on this site. i’ve noticed that people get very emotional about this hobby and a great number of them are intolerant of views that differ from their own.
If you think that cables, don’t make a difference, buy inexpensive cables. On the other hand, I don’t understand why the objectivists create so much anger for those who believe that cables, etc. make a difference. After all, people like amir cant dictate how you spend your money. He has an opinion. No reason to take it personally.
I think you generally get what you pay for in audio just like with most products. Those who believe differently are certainly entitled to their point of view. Why should I be offended by that? Buy what makes you happy. No reason for agitation at others who have a different point of view. This is listening to recorded music, not a Titanic struggle of good versus evil.
with that said, a good cable debate can be pretty entertaining, even though there is no chance it will add to the sum total of our knowledge on the subject
