Post Subject: The PP2000 with capacitance shunted batteryPosted by Romy the Cat on: 1/26/2011

I certainly have my hands full with those dams PP2000. As I least last night UPS lost one of my units I send to PurePower to repair. The shipment was insured but the saddest part is that it was the best sounding PP2000 of mine. So, I will not be getting a fix PP2000 this week. I hope to get my 3 working unit s sometime before I die…
What I did today was to load one of my PP2000 battery tray with 8x15000 CDE caps and slide it to my the only Ok operating PP2000 unit
To my huge surprise it was large Sonic difference with butteries shunted with large caps. I can’t make judgment at this point if the caps helped the PP2000 to be more decupled from electricity. I will be able to do it with time. For now I left the caps to format a bit for a few days as they are too new. I think some changed that I noted with sound will be changed as caps get more burn in. So, what happened with sound for now?
Fist is the bass. Believe me or not but if the PP2000 was phenomenal then with large battery shunted caps it is absolutely out of this word The Sound all together become harder, not bright but harder. The harmonics got eaten a bit and Sound because a bit faster, in fact too fast to my taste. The whole Sound become like driving BMW after driving old Acuras. Again, it got harder but structure not by more HF. It might be that I used too much capacitance or it might let hardness to go with time as caps will settle down.
I do not have opinion at this point if the change I got positive or not. I like some aspect of it and I do not like others. Let see what will happen when with the caps in a few days. BTW, publishing this data I under no circumstances solicit other people to do it, particularly if they do not know what they do. Let see how my result goes with time…
