I'm not sifting through all 7 pages of crap so I'll probably be repeating something. But, the bottom line is the AP3000.1 is going to do more power cleanly than the SAZ1500.
Hell, even AP 1500 vs. SAZ1500 the AP will put up a good fight. And here's a twist for the thread, I've actually owned and used both. //content.invisioncic.com/y282845/emoticons/crazy.gif.c13912c32de98515d3142759a824dae7.gif For the price, the AP is a very strong amp. For less than half the price of the SAZ the difference is very minimal and you'd have a hard time discerning which was which. Surprisingly the AP runs cooler than the sundown did. The sundown is a stout amp, if you can afford it. But 7 out of 10 people are going to be just as happy with the AP.
