In reading through the list of things you tried, I don't see that you tried connecting any other digital audio reproducer to the optical digital output of your TV or PS/3 besides a second ZVOX.
If you connect such a device and hear the pops, then you have confirmation the problem is clearly in the PS/3 signal processing.
The ZVOX 580 is essentially incapable of "hurting" itself. So the pops are simply annoying, not dangerous. However, I would consider them unacceptably annoying. Switching to analog audio would be highly preferable (in my mind) if it eliminates the pops. Also, switching to analog in this particular case (from the Sony TV's analog output going directly to the ZVOX) involves little to no overall quality reduction.
Analog audio's main problem is that it does not "travel" well (as in many yards or miles). When you go from microphone to tape, then to records, analog suffers big hits in quality. But converting a digital audio signal ONCE to analog in the Sony TV then sending it directly to the ZVOX using the Sony's "fixed" level analog output makes VERY little difference in the sound from the ZVOX.
As part of the ZVOX design team, I can strongly claim that the advantage of the ZVOX is ALL in the processing we apply to the audio signal (analog or digital). From the perspective of "sound out of the ZVOX", a high quality "fixed level" analog signal is essentially indistinguishable from a digital signal if the only "D to A" transition occurs at the output of the TV.
