Headphoneus Supremus

I was planning to get one ASAP, but naturally ran into financial issues.
One of the main reasons why I want this over anything else (besides the great price) is that there's a true line out that's not affected by the volume control at the front, so you can use the headphone out and have powered speakers plugged into the back and work them simultaneously.
