dedicated power line


HI,
I am in the process of having and electrician upgrade our home service to 200 amps. While he is at this it is quite easy for him to run a dedicated line for my hifi closet. What are the cost effective measures that i can have him put in place that have proven to upgrade sonic (and for that matter video) performance.

Thanks
Neil

Depending on where you live, you may want to CONSIDER a whole-house lightning / surge protector. They are not expensive and may save you some grief down the line....and, during an upgrade as you suggest, easy to do.
Neil,

While your electrician is at it, you may want to have him install a more robust ground. Since he has to disconnect the service to install a new 200 amp box anyway, a better ground can make a big improvement. You should have both circuits on the same leg and ideally opposite of your major appliances.
Receptacles are rated for either 15a or 20a, but as you said, some are not labeled. Should be on the original spec sheet.
