Power Supply Options - Pre Amp and Power Amp

Hi, I'm looking to upgrade the power supply for my hi-fi setup and wonder where I should start - quality power outlets, power distributor or power conditioner?

I'm considering a 3 to 4 outlets power strip so that I can plug all the power cord into it (instead of using a low grade, household one). My idea is to ground the cords from CD player, pre-amp and power into the same outlets to avoid "hum" noise.

FYI, my front end is Audio Research CD7 tube CD player, my pre-amp is Ayre K-1xe (comes with separate power supply) and Pass Labs XA30.5.

What's the simplest and lowest-cost solution? Can you recommend some high-quality power outlets (4 to 6 outlets would be great).

Thanks.

Thanks for your feedbacks and suggestions. I can start by upgrading the outlets (receptacles?) but I'm not sure if I will able to allocate a dedicated line.

What's a dedicated line anyway? My house was newly built a few year ago so the power lines are relatively new. I think they're 15A lines. BTW, my hi-fi system is in the living room. There're two wall outlets that I use for both my hi-fi systems and TV, cable, telephone, etc. Not sure the two wall outlets share the same line. Or, they are on the same line with other outlets throughout the living room.

Any suggestions how I can re-wire or allocate a dedicated line from the fuse panel? I'm not that handy with wiring. Shall I need to hire an electrician to re-wire for a dedicated line?

I needed the help of electricians but I am no DIY type. A dedicated line is an electrical circuit that is used by your audio equipment only. The Idea is to ensure that no other outlets or appliances share that line.
If you want to upgrade it to 20 amps it would be wise to do it while installing your dedicated lines.

I checked the markings in the electric panel. My living room has a dedicated 15A line for outlets and a separate 15A line for lights.

I guess I can unplug all other electronics (except modem) from the living room outlets to make it a temporary dedicated line when I play my hi-fi.

Are there any benefits of upgrading an outlet with a high-quality receptacle in the living room? Can you recommend some high-quality receptacles? I know Furutech has some offerings but I don't know about their price or where to get them. Thanks.
