I have two suggestions for most bang for the buck plus new purchase protection:
1) Go to Audio Advisor to take advantage of a PS Audio trade-in sale. You can buy the
PS Audio Perfect Wave AC-3 cables and then trade in some garden-variety IEC PC cords to get a 50% rebate. You might also consider getting this
IEC power strip to use one premium cord for up to three components.
I have been using a previous version of the PS Audio power cords and they are very good in a wide variety of situations. I used one with a switching integrated amp for two years, I use one with my HT pre/pro, and I use one now with my electric bass amp.
2) Go to eBay and watch for auctions run by ZuPromos for their
Birth power cords. These items are new-in-box just like standard purchases on Zu Cable's website and carry Zu's same warranty and 60-day trial and return period. Typically these items sell on auction for about 1/4 to 1/3 of the website list price. Most Birth power cords sell for under $40 on eBay.
I picked up nearly $2K worth Zu cables this way for about $450 and am *very* happy with them.
You just have to be patient; only one such power cable may show up for auction every day or two. But in a week you'd have all the cords you need for about 30 cents on the dollar.
