Upgrade Options for BPT Pure Power Center


I am planning to get a BPT Pure Power Center. There are many upgrade options available for the PPC and I am unsure which one would yield considerable effects compared to the standard unit.

For the outlets, I do not plan to upgrade them to FIM 880 or Oyaides but would appreciate if anyone could let me know if they brought improvements compared to the standard premium Hubbell 5362.

As for the other upgrade options, I am confused on which one to choose :-

1) OFHC 4N oxygen free copper 12 AWG Litz stranded wiring
2) 4N 10AWG solid silver wiring
3) 6N UP-OCC single crystal copper 12 AWG straded wire

The standard wiring is custom 12 AWG finely stranded oxygen free copper wire. I would appreciate if anybody would let me know which is a worthwhile wiring upgrade to the standard.

Any opinions and advice would be appreciated.

After looking at your system, I would suggest you may want to reconsider and go for the CPC or one of the BP units. I recently purchased a CPC that has most of the offered upgrades including a 300VA LoNo balanced isolation transformer for 2.5 amps of balanced power, which is perfect for running my cd player and isolating that from the rest of the system, while running my preamp and monoblocks off the other outlets. Options that I have in addition to the transformer include Bybees, 2 Oyaide outlets, a 30 amp high current filter, and ERS cloth. I believe the CPC offers more flexibility and may be a better value compared to the PPC. I believe Chris at BPT is currently offering a special buy on the CPC here on Audiogon you might want to check out. I cannot speak directly to the differences between the Oyaide outlets and Hubbels since I did not upgrade but received the unit already with the upgraded outlets. I can say they certainly grip well. For wire characteristics, you should probably talk with Chris at BPT.
Thanks for the response. I have emailed Chris and he is pretty responsive to my queries. I don't know what is the difference between the CPC and PPC but will find out soon. The upgrade options seem irresistible but the price of the unit may shoot up to 2X the stock unit or more, depending on the upgrades.
