OPA2365 and AD8565 are both excellent opamps in this application, I wouldn't necessarily say that the OPA2365 is "better", they're just slightly different and subject to preferences. The AD8565 has lower output impedance and much more output current capability, so it could drive low-Z loads much more effectively.
As far as the anti-clipping switch goes, no, it does not prevent clipping caused by excessive loading at the analog output. The anti-clipping switch's function is to lower the DAC's volume by 2dB to avoid digital clipping with some recordings. See the WM8741 datasheet for info.
Oops yeah i read your previous comment about 2365 incorrectly. Thanks for correcting me.
skimmed it..seems like the anticlipping switch doesn't apply to my situation at all.
I saw that the U7 is driving 3.5mm jack in the back but didn't see the front jack. Is the front 3.5mm jack driven by a different(weaker) opamp from the original gamma 1 design???
