Pick your poison, if a proper DBT test is done most people 99% of the people wouldn’t know the difference. I just pick out a decent well made brand that is well shielded and enjoy the music/movie. What I find ironic is that people claim that it make a huge difference but have a very hard time measuring it to prove it. Obviously different metals have difference sound characteristics, copper/nickel/gold/silver could make very very slight differences... What I find completely laughable is the huge sums of money people will spend on cables/interconnects where they will spend little on a better room or for that matter a better stand or better equipment. ;) All depends on a lot of factors if one can hear the differences, or "perceive" to hear a difference.
