Electrical Recommendation

I just upgraded my Panamax 5510 to the BPT-3.5 Balanced Power Signature Plus AC Conditioner and need some recommendations on the following:

1. Should I have my electrician hook a direct line to my system location?

2. What size fuse (AMP) should the direct line run from to avoid shut-offs. 20AMP?

3. Should I plug the BPT-3.5 Signature Plus directly into the wall and then all other components directly into the BPT-3.5 Signature Plus?

Some info:

Both systems are located on the same rack system. The chances of running both systems below at the same time are extremely rare since it's an open loft configuration in my home with different sitting mezzanines. AC upgrade in my loft building is not possible.

System A:
2-McCormack DNA 225 (225 Watts x 2 for both units at full power)
1-Sonance Cinema Sub Amp (625VA & 100W x 2 at full output)
1-McCormack RLD-1

System B:
1-McCormack DNA-HT5 (100W x 5 at full power)
1-ELAC powered subwoofer (180W x 1 at full power)
1-McCormack MAP-1

System A & B:
1-BPT-3.5 Signature Plus (recently purchased)
1-McCormack UPD 1 Universal CD/DVD

Please keep in mind, I never use my system at FULL POWER, most likely 50% power and then my neighbors start knocking.

Thanks for any advice you can offer. Electrician will be here next week so please answer soon!

Thanks!!!!
