If I'm not mistaken, the only thing the drivers of the X2 and SHP9500 have in common is the size.
Nah, forget Greece, the market here is tiny and what little is available is usually quite a bit overpriced. But I can buy from anywhere within the EU with no added cost, just more expensive shipping than if I buy from Greece. Import fees apply for purchases from outside the EU.
I've thought about the Hifimans, both the 400i and the 400s, but I've heard a lot of horror stories about their build quality. I treat my stuff well, but if it breaks on its own there's not much I can do. For a similar amount of money, I was eyeing the Fostex T60rp, but not only are they more expensive, they would also need a much beefier amp than my lowly Fiio Q1, so the total cost would be prohibitive at this point.
