vball,
I have the 3805 as well. It was the first real audio/visual component I have ever owned and was quite intimidated by it. That was a year ago almost to the day. I purchased the mic thinking that was the way to go and to be honest, it was a very helpful learning tool for me as I experimented with various speaker placements and eq settings that I might otherwise never had done. That being said, I'm like Mark, my eq is turned off. If you don't own it, I wouldn't buy it. If you really must try one, you can borrow mine. Just email me and we'll make arrangements.
John
