I just moved into a new house and want to give my system some good juice.  I only need one outlet so it should not be too bad.  I do have a few questions though.
1) When people say "dedicated line" do they mean to the street or just a dedicated breaker?
2) What are my optitions for filtering that line?  Isolation transformer?  What size is normally used for one system?  Do people mount these in the basement?

Thanks
Kris

Hi Kris,

If you're looking for useful advice, you really should tell us whereabouts in the world you are located because a) electrical codes and b) mains voltages are different in different places.

I think you are kidding yourself if you really do mean "I only need one outlet".   What about:
* sources ... tuner, CDP, maybe vinyl as well?
* preamp?
* power amp?

... at the very least! 

You need one outlet for each device.
Preferably, these should not be switched outlets.
Preferably, the spur feeding them should be 30amps (a "cooker circuit" size in Oz ... although, as someone has posted, you might be limited to the wires you already have.
Even better, you have one spur for each device (ie. a "dedicated line").
It's harder to filter the whole line ... easier to interpose an isolation tranny between the spur and each device.
If you want to get "heavy" about ideal mains power, go search Pink Fish Media for posts by Roy K. Riches.

Regards,

Andy

Who was looking for gospel? Although the internet is the FIRST place I come for advice.  Then to the pros or my father who is EE , uncle is an electrician.
Thanks for all the good ideas.

Trouble is, unless your uncle - the electrician - is also interested in hifi, he won't have the faintest idea of what things electrical make a hifi system sound better.    For instance, I bet you he would say "30 amp wiring is not required for a preamp or other low-draw source equipment"!

Only need one oout let because I have a power conditioner with ten.  I think I will put in two though.  I am in Boston.

hi Josh

I have a ground copper rod of 10 feet in my garden while "earth water"  is always there between 30cm and 1 mtr deep in the soil.( That ground is so "ground" i can I lit a 1 watt little light between that line  and the hot of the AC, dunno the English term)
That copper rod is connected to a thick copper wire  3feet long connected to my power bar. and a split wire to my heater pipers filled with water, which are 30 feet further connected to another earth rod of 3 mtrs deep  in the soil near the breaker box.  All my audio equipment is many tens of metres closer to my garden ground than any other appliance which ground is connected to that pipe near the breaker boxe .
So i dont have a real dedicated ground, but a semi dedicated?  No hum by the way

I understand now, never thought of it, that lightning strike will not only destroy anything along its path but has now 2 paths to do its ugly thing. Fortunelately only happened once in my life
 why the difference between the 2 ground will add a 3rd type of havoc i do not understand yet

Europe has a very different system then the US.  I don't think you guys use a 3rd wire for safety ground do you? 

I encourage you to do a bit of digging to verify whether your setup is safe or not.  Certainly it isn't kosher in the states.

And I would agree with the "uncle/electrician".
