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.

I concur with ZD542, especially on the power amp. The fact is that any better quality power amp will already have adequate filtering and such built-in and connecting straight to the wall will allow it to draw as much amperage as needed...

I agree with Tls49, dedicated lines with upgraded outlets should be the first step on your power upgrade list.

I use a product called: Furutech E-TP60/20. It's a 6 outlet case with 12 ga wiring and 20 amp receptacles, even comes with one of their nice power cords. (Google for more details). They make similar units less in price that may work for you also.

I plug my Pass XA.5 amps into the wall, my preamp and tuners (have several) into the Furutech.

For digital, you could use one of the Furutech outlets and hook up something with a "digital filter" but I'd try it without and see what happens.

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?
