It looks like you have enough equipment to put together several systems. I agree the Sunfire equipment, the amplifiers more to the point are world class. I have run amplifiers from Aragon, Acurus, Classe, Krell and many others and would agree 100% that Sunfire amplifiers offer the largest return for the $$$, almost no heat, no heat sinks, endless amounts of power, tracking downconvertor, and a true OHM's law experience of double the power as impedance halves. I would stack the Sunfire amplifiers against pretty much anything out there.
Great collection of equipment, Sunfire rules.
