I used to enjoy SRS WOW on my previous PPC : this app is fantastic to bring a much better sound while listening music.
Owner of an omnia, I never managed to have SRS WOW working (tried 1.2.1 and 1.5.1), and modified cabs for the omnia never worked on mine and according to reports do freeze the ppc (or need to stop screen auto shutdown)
So I was very eager to test this R2VS.
But the sound using this app is lightyears from SRS. In fact, I even prefer the unmodified sound !
By the way, no need to have this app to use and configure the native R2VS sound on every app (with less config possibilities). You just have to select a sound config in the samsung player (first button labelled 'norm' when not active), and the setting is used in the other apps like S2P & Windows Media player.
Well, still waiting for a successful SRS cab for my omnia...
