Pangea power cords

The Pangea AC-9 is the real deal. It's inexpensive an will offer an incredible performance improvement against any low cost power cord you're using right now. I ordered one and placed it on my tube amp and the improvement was immediate. More dynamic with sweet highs and a nice round bass with clear lines to it. I'm buying a second one this week if that tells you something.

I am certainly interested in these Pangea power cables. They appear to be well-built and are very affordable. The funny thing is that the AC-9 cord (designed for amps) is much, much thicker than the AC-14 (designed for sources). Given that my Headamp Gilmore Lite + DPS is a rather small amp, I wonder if the AC-9 is overkill? As best I can tell, I am using a 14 gauge cheapo Volex (the lesser 'made in China' variety) and it appears to be about as thick as the placement of my DPS can handle. Would the 14 gauge AC-14 source cord be a big enough improvement in my case? I know that the GLite supplies a high current and that the AC-9 is geared towards high-current gear, but I am starting to think that they are referring exclusively to full-size, high-power-consumption amps and receivers for speaker setups.

Is Pangea PC neutral or does it add warmth and softness to the sound?

Which model is recommended for a plasma?

Wish I could take part in the Pangea feast, but the configuration of my amps require a 90 degree IEC (pointing downward), so I think I'm restricted to the sidelines. Frustrating.
