I think it would be very interesting to see a head to head comparison of the Sony DA4ES(as a pre/pro only), Outlaw 950, or even Rotel 1066 and maybe some other dedicated pre/pros. It would interesting to see the results of such a test when comparing the Sony against some of the entry level processor units. Given the Sony's flexibility I bet it would hold its own in such a comparison, or at least be a very impressive $600 pre/pro. If anyone has some feedback on such a comparison, or have experiences with the DA4ES as a pre/pro I would love to hear it. The DA4ES seems like a relatively inexpensive way to get into the realm of separates.
