Belles SA-30 / SA-30 Gen 2

Can anyone tell me the difference between the two amps, what is their real power in 8 ohm ?
What is the difference between the older generation and the newer one and is there anything to be mindful of about these amps ?
The newest SA30 has Audyne Caps and sounds as good as anything you can put up to it. If you hear it in a well-supported system you wouldn't need to ask the question probably be busy enjoying music

Do you know what year the Gen 2 started production?
have a SA-30 on the way, one owner, says it is from 2015.
