I hear you. Im sticking with the QS's. I was venting, hoping the amps hear it and wisen up. I got rid of a pair of MiniMites years ago and I still miss them. Im sure I would regret letting these go unless there is nothing else to do.
Im just so tired of messing with tube problems.
Interesting you mention the F7...I was considering them....hmmmm
what did they sound like in comparison?
