Majkel, are you sure you have a small capacitor (the data sheet recommends 50 pF) from pin 6 to 8 on the AD797? It seems to be mandatory. It changed the sound dramatically in my amps, and there wasn't an increased current draw, noise, clicks, interference, high DC-offset or anything else indicating instability. That cap should probably simply just be there. There's still some sort of coloration in the treble like before but lower by a magnitude.
Since you like the sound of ADA4841-x, you should like AD797. It's a bit drier and lacks some of that colorful sparkle, but I think it's more neutral and does everything better.

I don't think it's due to stability issues because no symptoms of that have appeared in my circuit - normal power consuption and no weird behaviors while turning the volume knob or plugging the headphones. |
