I'm also going back and forth between IT01 at €130 and CH9T at €90, now that they are in a discount price, I am not sure if it's worth to spend the extra €40 for iBasso, unfortunately I can't buy overseas so I have to stick to the EU market
Although if the differences are not that extreme between these 2 I could go for the more affordable option. I'm mainly interested in midrange, lush guitars and vocals, clarity and good soundstage, also my source will be almost exclusively my HTC M9 and I will use them on the go, never at home.
So I don't know if it's worth to invest more if I don't have any better source at the moment. Any further input is more than welcome!
