DIY input buffer for nc500/purifi

[nerddude]

I am currently in the process of designing buffer board for purifi/nc500 modules. Any feedback on the schematic is appreciated.
Will share layout once I have it.

Have you seen the BTSB one?

Dunno whether suitable for this application.

But I like the ability to accept balanced or unbalanced inputs, and to output both!

Balanced inputs can always be fed from unbalanced source with the right cable.

Also balanced output is the way to go for most amp modules. So I prefer simplicity and built to purpose for best performance.

Hi nerddude.
Did you succeed in making the buffers?
