That's wonderful. I'm also glad Topping replaced headphones. Points for good customer service. However, the optics remain the same for me. As a a consumer, reading all these reviews, both here and elsewhere, of all these products that are competing for my dollar, there are a number of factors I look at: measurements, customer service, product reliability and how the company represents itself in forums such as this. JDS is Top of the Pops in all those categories. I like very much how JDS doesn't make judgemental or snide comments about his competitors designs. That shows class.
