power cords and krell amps any suggestions?

I've been using Granite Audio 560 cords for my KAV-250 & 250 a/3.

Can't quite forget that first time--swapped out a cord, put on a CD, and my jaw dropped. :)

Haven't compared to many other similarly priced cords though. . .

Thank you for all of the imput. So far all I have done is get the FIM 880 recepticals one for each of my dedicated circuts. The first thing I noticed was how tight they were when I went to plug everything back in after the install. Then after turning everything back on I put in a couple of cd's and was very impressed by what I heard. There was a lot more detail and it seemed as if the background was much quieter (blacker). Before I buy any powercords I want to listen the system like this for awhile.
Thanks again for your help.

Hi
I have a KSA-250, and use Shunyata throughout my system.
Have been using the Taipan, and if you are still using the stock PC - you won't believe the difference. You can't go wrong at that price -everything gets improved: soundstage, tighter base, more revealing ETC..
If you have the budget, wait a little and get the new Anaconda version designed for amps - out in the next few weeks. (not to be confused with reg. Anaconda.)
Good luck.

Krell power cords supplied by Krell according to Krell are not necessary to upgrade. I have not replaced the power cord but added the Ultimate Outlet by PS Audio there is a difference. Base is deeper and the monoblocks became more musical. This Ultimate 20 amp outlet is plugged into both of my Krell monoblocks (350mcx's) by the way on a 20 amp circuit. The sound difference can be heard. I spent my money on the AC Ultimate Outlet versus the power cord!!!

I build PCs ($69) and assemble DIY Kits ($32) around the outstanding Belden 83802 12AWG in Teflon cable. Many of us have used this stuff for a year or two and are very gratified by the results as a surprisingly low price. Now that really great HD screw-clamp Shurter IECs are available, you can put together one of these outstanding PCs in a 1/2 hour with just screwdrivers, a toothpick and a knife. RSVP is you want to try one. Happy Thanksgiving!
