@cal3713, I am happy you have found the Jupiters to your liking, and I agree completely with your comment regarding the manufacturer's choice of Solens for the PREs. I know even the PREs are made to a price point, but I know in my case with the Super Victory IIs, those Jupiters were transformative. That cap really moved the speaker to an entirely different level of performance. I expected you would find that also to be true with your Accutrons, but one never knows for sure. It is always an experimental question in the end. Keep us posted as you continue the burn in process.
