Thanks for the link, it seems that the X1 are the best so far, also, in that link I was able to see an amp from creative whose software is very similar to the one I've, taking in count that my sound card and the one I saw there were similar (or perhaps mine worse, since its included on the laptop..), it seems like; although its decent-good, there are better ones.
Any recommendation of which amp would be the best for the X1? Budget of $100, $150 as top if its really worthy, but no more.
I would guess(?) a Schiit Magni ($99) would easily drive the Philips X1s.
