Thanks I've learned a lot, I appreciate the help.
A few questions remain:
1) I will have a new breaker box installed as part of this project. It happens to be about 10' from the audio equipment. Many have recommened a sub panel dedicated to the audio equipment. Is this just convenience? What are the benefits of a dedicated subpanel for audiophiles? I understand that if I use the master panel, I should keep the audio circuits in phase which each other and out of phase with other large electrical equipment. Maybe that's why a subpanel is recommended...
2) I plan to install 10ga wire for my amplifier. Some recommend that front end equipment are all plugged in on the same circuit using 12 ga, not 10ga. Why is that? Is inductance an issue with smaller equipment that draw less current? I was thinking that I would have three dedicacted 10 ga circuits in the end: one for amp, one for digit front end, and one for analog front end. Or, one 10 ga for amp and one 12 ga for everything else. What's best for front end components?
3) Does silver contact enhancers really make a difference?
4) Why is Square D so popular among Audiogon'ers compared to other widely used whole house surge protectors, say from GE for example.
