Since the Lavry has only AES out, I saw that Maudio converter AES/optical/spdif. So I want to go from the Lavry to the converter, then the optical in of the mac G5.
Does anyone know if I would be facing some latency or/and quality issues from the converting AES/optical?
Thanks for sharing your experiences....

A straight forward conversion from AES to optical (or visa versa) does not impact latency. Such hardware is a tiny fraction of a usec delay.
Optical link, as a rule, make more jitter then electrical connections. Where can it hurt? I would not worry about it for digital data transfer, such as going from AD to computer.
The place where such jitter does matter is when sending data to a DA. A good DA can Handel a lot of jitter. A poor DA will not remove jitter well, and so optical may have an impact.
The last time I looked, I did not see a single optical link spaced well enough to run 192KHz AES (or spdif). There are some devices that do 96KHz fine, but most AES transmitters and receivers on the market are for 44-48KHz. Make sure you get what you need.
The early Toshiba TOSLINK (optical) devices provide 12.8MB/s bandwidth spec, and that was aiming the 44.1-48KHz market. The newer devices I saw are at 15MB/s, not really a X2 factor one would wish for 96KHz, but one can squeak a 96KHz data through it.
