The DPS is an interesting table but falls short of the performance of designs from Galibier, Teres and TW Acustik.
When I auditioned the DPS/Schroeder Ref/Airy3 the detail and imaging were good, however timing and dynamics fell short of the others mentioned above.
The Schroeder Reference is virtually unobtainable new (ask anyone who has ordered one how long they have been waiting). The Schroeder is at its best reproducing small ensembles of acoustic instruments but is bettered on rock/pop (where bass guitar and drums feature) by the Tri-planar and Dynavector DV507 (although the latter isn't the best at imaging I prefer it to the Schroeder for rock music).
The Verdier is widely respected although I get the impression that many owners upgrade the motor/speed control units in pursuit of better attack and speed stability. There are better options available for your money IMO.
