Well,

I have to tell you, Meiko41 that I was pleased to see that a local guy got a new PP2000. I kind of on the verge to get another PP2000 and this was a good preview what newest state of the PP2000 is. Even it was very clear the with PP2000 the guys system was doing MUCH better then driven from the wall but it was not my own playback where I know how I shall be. Also, the guy palsy is challenged in few areas, the areas where I would like to look at the PP2000 critically. So, to have a final assurance that the latest PP2000 was up to specks I tool scope and asked the guy to measure his new PP2000. My primary concern was if they have addressed this problem with “fuzziness” that I reported in my unit:

Yes, the “fuzziness” does not exist anymore, wonderful! However, this newsiest PP2000 does much worse things then the “fuzziness” – it does VERY severe clipping under load, not only clipping but asymmetrical clipping. Amassing, I do not believe that APS ever tested this unit.  A regular 200W CLCRC powers supply of a preamp clips the sinusoid with perfect horizontal line down to a few volts; at time even more then it is clipped in the wall. Ironically the unit maintains perfect sinusoid shape what it driver from battery but clips when it connected to the wall. Since it runs fine from buttery then we cannot blame the idiosyncrasy of the load. The only thing that I can blame is the unit again has some implementation errors and never was properly tested. I took some picture that I will post when I have time later on.Romy The Cat
