Throwing out the manual without completely reading it?
Ashame you only found out about what Intellivolume can do now, but at least you figured it out eventually. I have the 605 too, and it's a good lil' workhorse. But this just goes to show you how a little research and/or reading can make a significant improvement in your HT experience, huh? In some way, I have been guilty of something similiar myself.....oh well, live and learn!
