Power Cables

That cross section view of pangea is ugly.

Edit:  just realized that it is made with a saw.  Those solder joints look uncrimped to me.  You want good copper-to-copper contact with the solder holiding all in place,   You don't want the electrons travelling through large masses of lead and tin.

Suggest giving Audio Art Cable power cables a try. I found even their entry level cables to provide SQ benefits that are clearly evident

Take a look at moon-audio.com and their black or blue dragon power cables. The under $500 black version uses quality Furutech plugs. I use them on my main system.  Big fan of Cardas and the Parsec is good for affordable PC.  

Just read some impressive stuff on Ice Age power cables, especially their upper range OFC line that’s still well within your budget, and I believe they offer a trial period so that’s definitely what I’d do.  Heck at this price you could get a PC for your DAC and streamer for not much more than $500.  Best of luck.
