I loved what the PP2000 unit did for my system over 3+ years however when it came time to consider upgrade (PP2000+ or PP3000+), it took forever with many broken promises to my dealer with money already paid to PP (by my dealer) to get a demo unit. It was over 8-9 months of frustration. When the unit finally arrived I very enthusiastically paid the overnight shipping to get the "plus" net-gen unit to my home. I powered down the 2000 and put the plus-unit right into the system. From the moment I turned it on (even before other components), a constant and loud buzzing like a hive of bees and other noises began to emanate from my speakers. Taken the plus-unit out and putting the PP2000 resolved the issue. In many iterations with PP, I was told that it must be my system, my grounding problem, etc.....and that all the units were perfect in design and fully tested. I subsequently talked with 2 other PP users who tried the plus-units with similar results, one with a digital system, the other with an analog system. There seemed to be no attempt by PP to realize they might have a design issue with the battery recharge or other circuit of some other poorly performing aspect compared to their prior generation of products. After months of trying to resolve the issue, get some appreciation that the plus-unit caused issues that the PP2000s did not, I gave up....it's a shame really as the PP2000 did wonders for my system for many years. The upside is that I discovered a superior product in my travels/auditions and since getting the Bybee v3, I'm as done as I know how to be with the topic of conditioners...
