Improved audio circuits to use with viletim's RGB board?

I know the audio circuit in the f-labo RGB kit from japan has been the popular way to enhance the audio on AV Famicoms. However, with viletim's new RGB board being far superior for video what's the best circuit for audio now? I know viletim's board has some kind of audio enhancing capabilities, but from what I understand it doesn't take Famicom extra audio into account. Any schematics or insight would be much appreciated.

Myself and a good modding friend ace have reworked the audio circuits of a lot of different models of the famicom and found fixes.
