1 pointI say, buy whichever brand you can get the best deal on. They are both quality products, so try to save a couple bucks to spend elsewhere in your build.
-1 pointsYou're forgetting something.... That Autotek 2000 watt, wasn't doing 2000 watts to start with. You may not be informed, but people that swap out SAZ-2000d's to SAZ-2500d's commonly gain around 1.5 dB. So, swapping to that Autotek to the SAZ-2500d I can see up to a 2 dB gain.
