the phaser i like most is the
moogerfooger 12-stage phaser.

unfortunately i don't have the ASys rs400,
but if it sounds similar to the smallstone,
than it is a good option.
the doepfer a-125 (6-stage) doesn't sound as good as
the moogerfooger, but it is the cheapest
in price, so you can buy two or more of them
for stereo processing and enhance it's sound even more.

if money is not the problem, i would go for
the moogerfooger.
