One thing about the MG Head -- if you're looking at having multiple sources, be aware that the Head only has a single set of inputs -- you'd have to switch cables to go between a CDP and a PS2 or dish, unless you're using an outboard DAC with multiple digital inputs and one analog output for all your sources.
