The Rotel 1070 sounds great with the 602s and one advantage to buying new is the five year warranty from Rotel. These amps also benefit from aftermarket power cords: deeper bass, blacker background, etc.
PS - Although the new Rotels share a similar circut design witht the older models the new ones have improved filter capacitors among other things.
