Confession of a poor power cord pairing for a Pass Labs XA-25


I recently purchased a Pass XA-25 to replace my Nuforce STA-200. I had replaced the power cord on my Nuforce with an entry level Silnote power cord which made a tremendous difference in sound for the Nuforce. However, when I received my XA-25, I apparently was in an extreme hurry and did not install the cord that Pass Labs included.
This evening as I was sorting through a big box of interconnects and power cords, I discovered a power cord that still had its factory twisty tie intact. After a few minutes of deliberation, I realized that this was the power cord that was included with the XA-25. I hooked it up and wow!.. Detail and Bass that I didn't know this amp was capable of.
Moral of the story.... Just because it's factory power cord.. doesn't mean it can't be good.

Hmmmm. I am using a ZU Event Powercord with my FirstWatt J2. Sounds great. This has got me wondering about the original Power cord that came with my J2. It's still in its twisty tie.

First let me say, that I thought the Nu-force was a great little amp for $400-$500. Comparing it to the NAD integrated that I had before, it was eye opening, then when I connected the $99 Silnote power cord, it got even better. If your looking for an amp to push 4 ohm, or less than 90db efficient speakers, it ain’t it.
The Pass XA25 has dynamics, tone, timbre, definition, soundstage, transparency and bass authority in spades. The first Album I played was Vivaldi, The English Concert, the dynamics actually startled me. The timbre/tone of instruments was outstanding. Don’t let the 25@8 ohm/ 50@4 ohm rating bother you. I would encourage you to read the Herb Reichert review in Stereophile, for a more verbose account.
