The Z906 can benefit from a mod like any gear without audograde caps, still I would not like to working on it just to see how risky to remove the black stuff spilled over the SMD, and the tight spaces for the new capacitors is not inspiring either. In my eyes the whole system is a creation of money saving because the design aim the opposite direction what is necessary for good audio. Switching power supply, plenty SMD on the PCB is not on the wishlist of the audiophiles. The class-D amplifiers evolved in the recent years, still a good question how much compared to the old existing parts in a good setup. The Nichicons in the PSU probably from the PW series and OK for music, with the TEAPOs the Logitech is close touch with the bottom of reliability. If you decide to mod this system some parts may not like the 1:1 swap to audiograde caps, and better to discover what is belong to the controlling electronic and analog section first.

I do not have the images you need, I only worked on 2 new pods, and I had an old amplifier board here a while back.
well there was on OP AMP which was the same old OP AMP from the Z5500 R4580I series. I changed that. i am not sure which it controls. but all is good as far as sound. now there are A/D converters 3 for center/sub /RL RR/ and FR FL. whats there now is

also do you think replacing the caps with audio grade would be a good idea? i am assuming the caps on the opposite side of the power board are all in the signal path?
