Absolutely EVERYTHING you need to know about POWERUS amplifiers

This ended up being WAAYY longer than I intended. I plan on making a shorter roundup of all the current Brazilian brands on offer soon that should be quicker, but I have added contents to the progress bar so you can check out the most important bits to you. Spoiler, these are SICK AMPS!! Powerus did not sponsor or send in any amplifiers for this review. I simply reached out to the UK supplier and got one sent over to look at, and send back. 0:00 Intro 0:42 About Brazilian amplifiers 1:49 About fullbridge amplifiers 3:27 External overview 8:32 Cooling 9:41 Power supply architecture 13:41 Output architecture 18:09 Preamp circuit 22:34 Build / assembly quality 28:38 Serviceability & design features 39:41 Switching frequencies 47:09 Testing preamp filter behaviour 55:23 Limiter functionality 1:00:15 Other nice design features 1:03:38 Current draw balancing 1:06:00 Smaller 1600w model 1:07:01 Final thoughts
