The imbalance issue is a common issue with all electrostatic headphones, as they are highly sensitive to dust and humidity. As for the X9000, according to feedback from the friend above, his X9000 that had a unit replaced after repair has been operating normally for 3 years so far, so it can be inferred that Stax is also improving its manufacturing process. A more likely scenario is that the products of the majority of users who remain silent are all problem-free—it is just that those who have encountered problems have spoken out, coupled with manufacturing issues in early batches. I consulted a local dealer who has sold more than 10 units of the X9000, and none of them had problems within the warranty period. Of course, he does not know the situations after the warranty expires.

The price increase will take effect on October 1st. The imbalance issue is the most common failure for x9000, because the mesh electrodes are not robust enough. I guess that's why most stax amps can adjust volume for each channel independently

Already bought the x9000 at e-earphone with a 5 years warranty. The price increase left me no time to hesitate😅

There is greed indeed, but the rise in oil prices caused by war is also an objective factor, and every aspect of modern industry is influenced by it. At least it provided an irrefutable reason for the price increase.

Stax is going to raise the price of its products by 10%. Thank U Trump🤬

I don't know the situation of the US dealer, but my friend in China confirmed that the Chinese dealer offers warranty service only when you use a STAX amp, and they don't provide cross-regional warranty services. Considering STAX is theoretically a Chinese company now, maybe this goes the same for the US market.

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

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
