Should I upgrade power cord for my preamp?

For pre-amp and source devices, especially digital,its all about noise control/reduction.

For power amps, its more about current delivery.

I use Pangea ac14se on both my ARC sp16 pre-amp and mhdt Constantine DAC at present. Each seemed to make things better, which I woudl attribute mainly to the shielded design of this model specifically for line level applications.

My Pass preamp is the only component I do not use an upgraded power cord on. Amp and preamp plugged directly into wall. Upgrade power cords on everything else.

Absolutely...power cords are the best way to upgrade your system.

I was a skeptic until I tried a PS Audio Premiere Power Plant. It made a huge improvement, so I decided to replace all my power cords with PS Audio cables. I used AC-10s for my amps and the PPP, AC-5s for everything else. It made more improvement than any interconnects, and I had dedicated 20 amp lines to start. They did take a while to break in, but both my wife and I heard a sudden step-up one evening. I wrote the company and asked if they ever got mail like that, and we were not the first to experience it. The Cable Company will let you borrow cords, and I expect you will hear clear differences, too.

Hi Elegal

What is the model/make of your preamp? Also what do you find wrong with the sound in your system that is prompting this desire to change? What is the current power cord that you have with your preamp?

For my preamps I like to use 14AWG power cords but that is just me. The power cords that I use on my current preamps are Shunyata Venom 3S power cords. The reason I went for these was the price and I didn't like the stock power cord that came with the preamp. Cruddy connectors and it was 18AWG power cord.
