I bought my bro Klipsch X10s, he broke the jack within a month, worst purchase ever.
Fiio E11 and E6, frankly the E11 is a great amp, but somehow I always seem to receive defective products, even after RMA, I totally give up, jack failures/loss of one channel, sucks when you are overseas and your amp fails. As for E6, it wasn't resolving enough to me. I'm switching to getting cmoyBB or something like that for my portable needs. The E6 was 2 months old, 2nd E11 was 3 months old before it became faulty.
Fiio RC-UE1, I waited 2 months for my order for the RC-UE1, only to find out overseas(in Beijing) that there is a product recall. They failed 2 weeks after I gotten them. damn, currently waiting for a replacement RC-UE1. Hope I won't regret waiting 4 months for it, since my Fiio interconnects are all working well and fine.
Seriously FiiO I wanna use your stuff, they sound great for the price, but make it higher quality!!!
