The resistors marked with a red circle are 42K instead of the standard 27K fitted to the Gator. You could even go up to 56K but sound clipping will occur at high volume levels. Mind you, at that sort of level you are likely to go deaf very quickly.
I am a proud owner of a new Caiman+ with Gator -- thanks Stan for the very fast turnaround. First impressions are very even performance with no obvious weaknesses.

One thing I noticed was that the volume (fixed output) of the Caiman with Gator is lower than my other dacs. Does the 42k resistor mod affect the fixed line out also, and my how many dB? I'm looking to a mod to increase gain sometime after my Caiman has bedded in.
