amplification for ATC SCM35 speakers


im considering the following amps: Bryston 14B SST, Jeff Rowland Concerto integrated or 201 monos, or ATCs own SIA150 inetgrated or their poweramp. what would be the best and most economically smart move? as far as ATCs own amplification goes at least i do not have to worry if it will sonud good with their speakers...
right now im leaning towards the SIA150.
