Hi samhvcc,
I haven't heard the Jadis JA 80 but given the description of them on the Jadis web site leads me to believe that their sonic signature would be very similar to the smaller JA 30 mono blocks. The JA 80 doubles the number of power output tubes. Each mono block is heavier by nearly 30 pounds.
That's a quite substantial weight gain and suggests larger power and output transformers and a lager more robust power supply. One would expect the JA 80 to be a better match for the Sony speakers as compared with the smaller Jadis JA 30. So in essence you gain power (And presumably more current capability) with an identical or very similar circuit design.
