From my listening experience all I can say, the Amazon Reference impressed me much more than the dps with any Schroeder Arms ( I listened to a few of them ).
I know, it is not quite comparable, because they were not in my System, but the overall high frequency information and the musical flow through the whole range was better with the Amazon / Morch / Lyra than dps /Schroeder/Lyra's.
