As I heard the avr 630 I found that it has a lot of power but shifts detail somehow in the background. The 430 had more detail to me and sounded more prezise. I could not hear the Marantz Sr 7400 so far. So, did anyone hear both and can compare them both. Has the Marantz more detail than the avr 430 and has the 430 on the other hand more power? Which one is more dynamik in Multicahnel Music and Movie? Comments from people who have heard on or the other or even better both are welcome.
