Question Some questions about Apple AirPort Express

Hi all,

I buy an Apple AirPort Express and want to do diy to improve the performance. But it is hard to know the part number audio DAC. I'm sure that the chip is not PCM27XX. I think Apple changed their hardware after 2008. Does anyone know it? I need your help, thanks.

The D/A converter in AE is CS4344 from Cirrus Logic.

I think I'm wrong. The chip marked with AATBBY should be an Amplifier. I hope I can find the part number.
