I thought you were gonna forget about auto-setups..

I also thought you did find it and was confused about how it set your db's up? Either way.
In all seriousness, I don't care for the auto-cal stuff. Every time i try it, I end up changing something anyways. That said, the receivers you are looking at are nice and I'll never steer anybody away from spending money on audio gear unnecessarily.
If the receiver you have just doesnt cut it or you want more features, by all means, upgrade. Just don't expect massive changes in sound.
I would probably steer you to the shack and get your hands dirty with an SPL meter. Its amazing what you can learn when setting up your own system, and if your married, the amount of respect your spouse will have for you. /sarcasm
