I have a Cowon D2 source combined with Ultimate Ears Super fi. 5 Pro IEMs (what a mouthful!), and I'm pleased with the excellent sound of the Cowon playing FLAC on the go. However, I've noticed that the Cowon paired with the UE5s produces an unpleasant hissing noise, and I've read that an impedance adapter is the best way to remedy this. Now, in my search I've come across this many times, but I'd like to know if there are any comparable adapters. I'd buy the ones in the link above, but I don't feel like going through eBay right now.

Any help would be appreciated, thanks.

APureSound sell some of them, if you want an alternative.

Thanks mate, the ones that I saw on their page looked great. One last question, though: what impedance rating, 75 ohm or 120 ohm, would you recommend for my setup?

Thanks in advance.

With the D2, I think 75ohm is enough to fix the bass roll-off.
