Has anyone listened to these 2 receivers side by side? I have read many rave reviews on the 7200 but not much about the 630. The 630 can be had for just over $700 delivered and the 7200 for just over $900 delivered. I like some of the additional features that the 630 has over the 7200 and I do not currently need the extra power of the 7200. I also like the new styling of the 630. Any comments?
