Don't worry, I didn't take this as rude at all. I'm not sure why you made your comments regarding opinions, as I didn't ever say anything contrary to what you said.
I ran the IT03 off my most linear and well-behaved source, the AP100 -> FiiO A5. Of course, I also tried it straight from the AP100 which made no difference in terms of sound. I used medium silicones, which couldn't really get my left ear a good seal, and some of my personal Comply eartips that came with another IEM. I spent a little over an hour with them before my friend who owns them had to take off.
However, I've written over 45 reviews at this point, so I've learned what does it for me and what doesn't. I've really only been caught off-guard by a couple IEMs with rather esoteric tuning that required some brain burn-in. However, what I want from an IEM is likely not what you want from one when it comes down to the specifics, and like you said, these are all opinions, so I'm not sure how you take issue with mine.
While I don't mind engaging with you further, this is a Rose thread, not an ITO3 one. Send me a message if you wish to continue.
