Post Subject: APS is coming, APS is coming… + some bitching.Posted by Romy the Cat on: 7/19/2007

I have to admit that my first unsuccessful experiment with APS PurePower regenerator made me anxious like hell. In context of the none-loaded unit I’ve heard some results that I was searching for a long time. The APS claim that they have “fixed” it and claim that now this unit will deliver at full load the same quality as I heard at 10% load. If it be true then it will be not just exciting but the “Fucking Exciting!” as it would conclude my many years quest to resolve electricity problems and will address something about which I hold a large white flag for years.

The unit should arrive on Friday and I am so atypically “frantic” to get it that I even made the special arrangement for deliver in order to get it on Friday. God, is it possible that this damn regenerator will work properly and that I will never have bad electricity again? Ok, let do not temp the fate…

Anyhow, one point I would like to mention, still. The APS reported that they did not “fix” the unit (juts replaced the buttery) and it worked perfectly fine during their tests; they sent me the measuring data and it did look good. If it is so (and who know the truth), then the most probable reason for my negative experience APS proposed that some of the contacts in the unit’s board was not correctly functioning and it inflicted the APS’ processor that run their software. Well, it is not a good thing but, hey - it happens! I have no problems with the fact that it happened, however I have a BIG problem with the fact that the PurePower’s start-up initialization routines did not detected that something was wrong with the unit’s output.

You see, the distortions problem that I experienced screw up sound very severely BUT the unit keep functioning. It is VERY-VERY bad. I did not measure the distortion at that time but looking at the very strongly corrupted wave it was in tens percents and I would very much prefer that the unit shun itself down (or alarm me). If the unit does not do it then what the purpose of it? If tomorrow my Cat decided to jump on the unit or if I move the unit and as a result some kind of internal board will not have a good contact again and then how will I learn about it. Sure, my Sound will go to toilet but how much time should I spend in order to detect that my power regenerator decided to show some attitude? If something is objectively wrong with output then the regenerator should alert about it. I intend to run my distortion analyzer and scope parallel with output, but I am not willing to do it the long run. From this perspective the PS Audio built-in distortion reader is useful, I juts hope the PS Audio regenerator sound also in a useful way…

Well, the distortions reader is completely unnecessary and the regular threshold alarm if the distortions went over, I would say, 3% will perfectly do for me. I personally, being a nerdy freak, would love to see the real-time wave monitoring and in the today’s world it would take $10 to implement….

Well, let wait Friday and see if all my “while I am I anxiously expecting” comments were worthy… What I know is that since I heard what the APS did with electricity that drove my front-end I was hardly listening my “big” playback (the electricity is horrible here for weeks)… So, I am Audio-wise kind of in my “summer mode”…
