After many unanswered e-mails, I got word from APS today, who said they have had a few customers with similar issues and that it seems to be system dependent. However, they also said that they were working on a way to fix this that they might have in as soon as a few weeks and that they will not charge anything to any customers to make the necessary corrections. Well, okay, we will see.
Actually I do not find it as satisfying answer and I am surprised you do not ask them more. The system-dependent explanation is NOT an explanation at all. If the regenerator does not run DC and has virtually null between ground and neutral then the regenerator is fine. The system-dependent explanation explains nothing unless very precise specifics of you system that was allegedly responsible for the problem was identified and named. If they say something like this for example: “the noise of 60Hz was is due to your system have an impulse power supply in one of your load” then the system-dependence makes sense. However, if they use the system-dependent justification but without naming the dependence from something very specific then this explanation is absolutely bogus. This explanation is as absurd as us the word “synergy” for components matching - it gives an illusion and justifies the problem but serves no useful idea for system building. Anyhow, I hope APS or you will name what specific attribute of your particular playback was responsible for the noise. I have no noise of any kind now but does it mean that if I add one more component with not favorable PS then my system-dependency will turn to negative? I need to know what the problem is and if the people who do not have the problem NOW need to pay attention and to implement the fix that might prevent the future prospective noises.
