Hi folks....sick at home with the flu and bored out of my alleged mind. I'm about to pull the trigger on a new head. I was surfing the reviews Harmony-Central (no affiliation) and decided to compile a ranking of heads. The attached spreadsheet shows amp heads that were reviewed by 10 or more reviewers. I figured it was a good starting point for enough opinions to be averaged. YMMV. I then took the total scores for "reliability" and "overall satisfaction". There's some interesting results for what it's worth. It's amazing what boredom will drive you to.
