Coacher, I can't answer you about the difference in the two platforms you've specified, but I can highly recommend the
Walker Audio amp stands.
Dave Robinson gave them a Brutus Award in Positive-Feedback Online in 2005 and 2006 (and continues to rave about them) and his comments match what I hear with them under my Atma-Sphere MA-2 amps:
Another winner from Walker Audio: the Prologue Reference Amp Stands and their associated Valid Point Tuning Discs have become absolutely indispensable to me. The sonic qualities that set the Prologue Amp Stands apart are the detail, quickness, and sense of spaciousness that they impart to components placed on them. Tubed and hybrid amplifiers definitely benefit from being mated with the Walker Audio Prologue stands. This doesn't surprise me; both Lloyd Walker and Fred Law are big fans of tubes in just about everything except phono amps. I would expect this to be reflected in their approach to amplifier stands—and it is.
