I believe the same reviewer at 6moons wrote up both of these CDP's. You might compare his reviews. I bought the Raysonic based on his review when it first came out and have not been disappointed in any aspect of its performance in comparison to the Wadia 302 or the BAT DK5 which I also use in my system. My guess is that you will find the Raysonic will have a fuller and more dynamic sound and the 2.2 will be more linear and precise, sort of like the difference between a lot of ss stuff v tube stuff (even though as I recall the 2.2 does use tubes. You might also come to this same conclusion of the sound of the 2.2 by 6moons comparison of it to the Droplet which it also reviewed. In than comparison they mentioned that the Droplet had a longer decay compared to the 2.2.
Anyway its a good read. Draw your own conclusions.
