Fiio e17 Diassembled for mod

[HiFiTunes]

This is my first thread and it's my first DIY. I plan on changing the AD8692 to a OP1612. I have looked over specifications of both opamps and I believe they are similar enough to do this upgrade.
 
Before I actually get started in desoldering the AD8692 I would like to get an input from the community.

Hey there. Never thought 2 years later you'd get a response. Well, I don't have much of a knowledge of opamps, but I do own a FiiO e17 and a pair of MDR XB1000's... so I am very interested in hearing what you did do.

I played around with the 49720 and the opa 1612. The quality change WAS SIGNIFICANT for the better. However the amp died eventually. I only did this because I was making the B22 amp. I have yet to learn more about amplifiers and touching this amp was not a good choice for me. It was an expensive lesson. 
 
 
Don't touch it unless you know how to match the opamp with the existing circuitry or modding the whole circuit itself.

Alright. Won't touch. Haha. Thank you.
