David, we've been anxiously waiting over three years for your first post, so welcome. As to the receivers, you can probably get the 3007 for about $500 less than the 5007. There's no appreciable difference in maximum power or other general performance aspects, so unless the 5007 has some added feature that you really want, the 3007 is a more cost-effective buy and that budget can be used on something more meaningful.

Enjoy the music, not the equipment.
