That Blade amp reminds me of the older PPI Art series, probably from the same era.
Pyle never really made anything worth talking about. Sony made some very nice amps back in the 90s/early 2000s, you'll have to either look for the "Sony ES" series or ones that are stable down to 1 ohm, those are the good ones.
Sony did make a 2000 watt amp, the Sony XM-2000R, it was the best amp that Sony has ever made but besides the photos on realmofexcursion/ampguts I've never seen anyone with it or have it running, it is ultra-rare and really expensive.
