Geee...this should be interesting as I will be picking up my Opus 7 next week. I had the caps changed and gave it a minor tune up. Can't wait to hear it. When I bought it I was afraid to power it up w/o having it checked out fisrt. I hope to use it in my office.Sounds like the only difference in the 6 or 7 is audio adjustments if I read this thread correctly.
