Over design was a traditional requirement for audio power systems
Audio systems typically have very high peak power requirements
Crest factor of 10:1 is not uncommon
To meet these challenges the Power train needed to be large
Power transformer large to support peak flux
Power Switching MOSFET (and hence drivers) big for high peak currents
Meant that CEC and Energy Star efficiency targets were hard to meet
