Looking to try some different op amps in my WNA III headphone amp to replace the LM6171. Possibly the AD797BRZ. I was wondering if anyone has any recommendations?

I have only the WNA MKII. But now I changed from OPA627 to AD797 and compared my WNA with other HA. I was thinking that the amplifier might start swinging, but it went well. More details, different sound than with OPA627, sounds better to me now! I used the AD797 as it is - and not the modified version with the bent pin. I am still considering using additional capacitors, as suggested in the data sheet. www.analog.com/media/en/technical-documentation/data-sheets/AD797.pdf
