Using the latest PCSX2 beta and spu2ghz beta 1.3 i get the following:
Ar Tonelico : Buggy voiceovers completely gone, some quirks but game is fine now

Final Fantasy X : Campfire intro still loops some samples but got better. Voices are fine.
Grandia3 : All randomn disturbing noise is gone, some quirks left but much better now

Xenosaga : While generally fine, sound is kinda "slow", like fps was 55 instead of 60 ^^
You've improved the plugin a lot since the earlier versions. Thanks for the hard work
