Also, does the 550 require a regulated AC adapter? I asked iriver this question twice and never got an answer. I ask because I bought a 4.5v Radio Shack ac adapter that is rated at 1600 mAmps. But the package does not say it is regulated. When I turn on my head phone amp hooked to the line out I get a hum with the Radio Shack adapter even though the 550 is not turned on. As soon as I power on the 550 the hum goes away.

I just want to make sure I wind up with the correct AC adapter and don't damage the 550.

Thanks.
As long as the Sony adapter is the right polarity & voltage, it should work fine. It will charge a bit slower, but it shouldn't be an issue unless you are in a hurry and have run the battery far down.
