If the APS works as I described in the paragraph above then the buttery does not filter/buffer the source of ASP’s oscillator and amplifier. In this case I would like to get rid of the buttery and do not let the APS circuits (allegedly faulty made) of the buttery charging to affect my sound.

 
   Exactly !!! This is the sensitive part that nobody want's to talk about !!!

   If the APS do source oscillator and amplifier from buttery regardless if the buttery is being charged or not then the buttery acts as a perfect capacitive tank and the buttery is good think. 


   Right again ! In my opinion this should be by default... I don't know why PurePower would do it otherwise...

 In this case we just need to wait until APS will finish to purify what they currently do, hoping not introducing any new problems…


    I don't think we will ever solve something this way. The solution is quite simple really ! All there is to do is to remove the batteries and start the unit. If it works than the answer is obvious... the unit IS NOT 100% ISOLATED FROM THE WALL and the battery acts up only when the voltage is too low (or absent) to guarantee the output of 120V (US) or 230V (Europe).
 
    My feeling is the unit will work without the batteries but when the voltage will sag the APS unit will sag. I say this becouse I heard someone say that when one of the batteries of his unit got defective (he couldn't start the unit from the battery mode) than unit kept going connected to the wall.
    To be sure of this we have to check. I plan to purchase a 700 model in October. My system is Class A also and draws a steady 500 W so I think it would do. Anyway my budget doesn't allow me the 1050 model and the money lost on a bad purchase is lower this way.
     If nobody tries it until then I'll remove the battery tray and see for myself...

Best regards,
Lucian
