Zanth-
First, thanks for doing this and sharing it with us.
Second, does anyone know whether the drivers in the PS-1s are actually different than the RS-1 drivers? What if in fact the drivers are the same as the RS-1s and the sonic differences are a result of the PS-1 driver housing and dampening techniques?
I have not heard either the RS-1 or PS-1, but hopefully someday I will make it to a meet and have that pleasure.
