I love the sound of audioengines for my desktop. I have the HD3s at one desk and just bought the HD4s for the other. HOwever, the HD4s have trouble attaching to my computer so I just returned them. Got tired of troubleshooting. Can be a real pain when you join a meeting at the last minute and the speakers aren't connected. Audioengine said, "yeah, we've had a few complaints about that. Hopefully an update will fix it eventually."
I ordered some PSB Alpha M3s and hope they sound as good.
