Building the Audio Note Kit 1 SET amp...

Rebbi,
Your amplifier is worthy of much more than an old PC cord. Even though you are quite please with the sound quality you are currently receiving, this generic power cord is limiting your potential significantly. You'll be surprise what a higher-quality power cord can do for your amplifier.I would recommend that you consider purchasing a high-quality used power cord, for example Coincident, VH audio or Triode Wire etc. these are great value buys especially used. This level of quality power cords will noticeably increase the overall sound of your amplifier, they do make a difference.

Charles,
I know that speaker cables can make a difference because I have heard the differences myself. I will admit to having been a little skeptical about the whole power cord thing but I will certainly give it a try.
By the way, do any of you guys know anything about Silnote? They have some power cords for sale here at very reasonable prices.

Rebbi, I agree with Charles you can do much better then the Pangea. Buy used, Triode Wire Labs cords are very good. Pete (TWL) might have some used ones. He is great to deal with or look on Audiogon.

Pangea has one model for power amps (focus on current delivery) and one for source or pre-amp (focus on noise shielding and control).

I use the latter (AC14SE) with both tube-output DAC and tube pre-amp and can state with certainty that these made a significant improvement in detail and clarity with my gear.

Neither is a perfect fit for an integrated amp though so I would recommend going with something that others have had success with used with a SET tube integrated amp specifically.

Rebbi,
Pangea is a decent cord, I believe Silnote and the other examples I mention are in a higher quality tier. Get a upper level cord like these and enjoy their better performance for years. In other words, match the quality of your amplifier.
