Ok gang, put your thinking caps on ! I'm looking for a device that can be used for multi purposes. I'd like to use it as: 1. preamp, either into a poweramp, or to pa. 2. pratice amp, with cd/mp3 input and with headphones. 3. Direct box. 4. mixer/blender The Raven Labs PHA-1 is very close to what I need, except that I don't believe it can be used as a headphone amp. I prefer to have a unit with 2 channels, such as the PHA-1. Basically, I want the PHA-1, but with headphone capability. Any suggestions?
