TAS3251EVM: Post Filter Feedback - Zobel Network

Part Number: TAS3251EVM
Other Parts Discussed in Thread: TAS3251

Hello,

I was just studying the TAS3251 EVM schematics as well as the EVM Board and saw the implementation of the PFFB network similar to SLAA788A.
In the EVM documentation the filter network is crossed-out (see below) and I was wondering why ?

SLAA788A shows a significant improvement of THD and SNR and I was wondering if thats not the case for the TAS3251 ?

Best regards,

Sebastian
