Wow. Bite the hand that feeds much?
You take what is by far the most extensive and quite possibly the most worthwhile IEM comparison in existence and crap all over it because of how they were obtained for trial listening?
How in God's name would someone be able to compare 300+ IEM's for everyone if they had to purchase every last one of them on their own? Sit back and ask yourself that question.
I for one am thankful that ljokerl has a reputation as a solid, reliable, and objective reviewer of IEMs such that manufacturers are willing to send ones for trial listening.
