里面关于奇美的电源线试验是这段
Before we packed in the session (reluctantly as you can imagine), we wanted to try one more test. Linn's Canadian distributor had sent us a message urging us not to use the player with any power cord other than the one supplied. It wasn't obvious why, since the cord appeared to be the usual $3 molded cable. The next day we got an e-mail message from a reader who owns an Ikemi. He had bought some Wireworld Stratus power cords from us, and discovered that they transformed the sound of his system...with the exception of the Ikemi. With the Stratus, he told us, the Linn player sounded shrill and unpleasant. What in the world was going on?
We had done our listening tests with Linn's own power cable, but we went through the last song again, this time with a Stratus power cord in place. What would happen?
Less than we thought in fact.
The player certainly didn't become shrill. Indeed, it didn't really become anything. The Margie Gibson song sounded virtually identical to the way it had been, and even after listening twice we couldn't agree on whether there really was a difference, let alone whether it was an improvement or a deterioration. That much surprised us, however, because we usually advise audiophiles to upgrade the power cord of the CD player (or the DAC in the case of a two-box player) before any other.
This is not an ordinary player, however. Remember the presence of the switching power supply, which works totally differently from the conventional transformer-rectifier-filter setup found in nearly all audio gear. We know that power cords often act as radiating antennas for digital data, which then gets where it shouldn't...and sometimes as a receiving antenna too. The Stratus, like other high end power cords, is shielded to prevent that. Linn claims that its switching supply is simply not vulnerable to the antenna effect.
Of course the Stratus has another advantage too: superior connectors (including a Hubbell hospital grade AC plug) at each end. A better contact with the power line is always a Good Thing.
