Hi,
when i use ST DAP + ST516B, My PVDD is 51V,
but when i replacement ST DAP to TAS5508, my PVDD should be 53V to make same power output Watt,
Do you have any suggest? thanks!

Ray,
I don't know the ST516 or ST309, I couldn't find much info on them.
From your plot it looks like the ST309 is providing something that is NOT standard PWM output. The TAS5508 is providing 50% duty PWM that will have varying PWM duty cycle when audio is playing. You will need to figure out the input that the ST516 needs. The TAS5508 cannot output the same signal that the ST309 is currently providing.

Ray,
You will need to look at the amplifier configuration as it will require a certain input type. Maybe there is a setting to change on the amp so that it will work with the standard PWM input that the TAS5508 is giving.
