It's not a matter of amplification. As you pointed out, jamma RGB signals are generally at high levels. So why use a video amplifier IC?
To place the video circuitry of the arcade board under adequate load. It is designed to drive high level signals.
To buffer the video and have a cheap point of failure between your expensive arcade board and monitor.
To output at 75 Ohm impedance.
HAS supergun has been doing things right for 4ish years now. It's not really a new concept, but one not many people adopted. We owe RGB some thanks for steering us all in the right direction.
I believe that 8 DIN VGA breakout cable would work but haven't looked closely into it. Mind you, if people want to run two video outputs simultaneously we'd be better off using the THS7374, which is capable of driving two separate outputs.
