I see that the AKG 240s MKII can be had for $129 on amazon. I think I'll give them a try. Can anyone recommend a good budget headphone amp to go with these? Preferable one with a usb input so that I can connect directly to my PC and bypass the soundcard? I know HeadRoom makes one. Are there any other some of you may be using?
