I am planning to buy the Stax x9000, but my friends say that the x9000‘s driver is easily to be malfunctioning, and the cost of repairing it outside of warranty is very high as we know. Therefore, I want to do a survey to see what the failure rate of the x9000 really is.

Thanks in advance for participating in the survey

My first pair suffered the imbalance issue within a year. The replacement pair have been solid for over three years. My dealer was astonished that Stax sent me a new pair. I chose to interpret this as meaning they knew they'd manufactured a faulty batch of headphones.

Thx for replying. So you mean the early batches of x9000 may have some durability issues and stax have fixed that. That's good news I think
