I am also in the same boat considering few amps for my PSB Image T6 and my list is exactly same as yours but I am considering Arcam (A19/28) also in to that, though A28 is above 1000.
You could possibly look at Rotel, Cambridge Audio, Marantz, Quad or Audio Lab. Refer to their high end or top power amps....Check the technical specs in terms of power output, impedance and frequency performance...as per your requirement to match the speakers...
