Which Power Cords: I Need Some Informed Guidance

From what I have researched these powercords seem to be
a very good bang-for-the-buck:

1. Audience Powerchord
2. Shunyata Taipan (If you can stand the putrid lavender ends)
3. Acoustic Zen Tsunami
4. Analysis Plus Power Oval 10

I ordered a Tsunami myself but it hasn't arrived yet.
I'd love to hear if anyone has done a shootout with these
above powercords..

Power cords are system dependent (like virtually everything in audio), and unless you happen to own the same equipment as someone who has done a shootout, their comparison may or may no apply to you.

The only way to determine what power cords work to your liking is to try as many of the possibilities as you can in your system.

Buy-and-Try.

You are 100% correct. Makes a lot of sense..

I have had a hard time "believing" in the power cable has sound qualities argument. With that I just installed a pair of "massive" power cables I won off ebay for $37.00 a piece/plus shipping.
These babies are massive and seem to be well constructed.
They are called "Miova" brand. I plugged them into my Acoustats and I must say I can hear a definite improvement. The already good soundstage has gotten deeper and the whole system seems to be quieter.Which leads me to the question;what am I getting,better current to the speakers(cleaner)or is it all about the shielding which is keeping my interconnects (Prosilways) from interference?

The system seems like it has more headroom which makes me feel like there is more current and or cleaner current.

I am sure that there are folks on here that can explain it so I will sit back and listen.:-)

I have heard this over and over in my system as elements have been added/replaced that lower noise floor. A lower noise floor often results in an apparently louder sound.

IMO, system noise is often misunderstood. Some people expect system noise to be an easily recognizable hiss, buzz, etc., and sometimes it is, but there is system noise that's extremely subtle and difficult to "hear". However, when this noise is reduced, the effect is a clearer musical signal, and often a perception of playing louder, because one doesn't have to turn the volume as high to discern micro details in the music.

After market power cords can lower system noise by reducing noise in the AC delivery.
