Question new 4780 amp.

Hi everyone.

I wanna make an amplifier using the 4780 chip.
I'm trying to understand witch design is best but it's very hard.
I have some questions.
- Inverting or not?
- output snubber yes or not?
- Ci cap on the feedback yes or not?
thank you.

as alternative I believe is better than 4780 no need to match components when parallel chipamp and better peak current delivery, see this website,

I bought a single pair of o/p trans. which can deliver 100w into 8ohm. still waiting delivery.
